Heavy Stuff

Today I got a SMS from my local bike store. They finally deassembled the Maillard rear hub.


Good news indeed. As I wrote previously, I was so stupid to remove the hub from the wheel before removing the cassette from the hub. Which is a minor glitch if it happens with todays technology, is a major pain with the technology of yesteryears. It’s almost as bad as trying to eat a marmalade sandwich while playing soccer on playstation 2. Believe me, everything can happen in that situation.

On the weekend I went to a DIY shop bought a large plank and some steel screws and nuts to construct something to counter the cog but it didn’t worked out when we tried at the bike shop. Luckily the good people there were so moved by my engineering efforts that they agreed to give it another try later: When I am away and I couldn’t take a peek at their trade secrets.

The guy told me today that he built up the bike again to counter the removal tool which was connected to the wheel. Then finally he was able to unscrew the cassette. Which is actually not only a cassette, but a cassette with an integrated freewheel. Probably a Dura Ace FA-110, if you are interested in the details. Coming home I started to clean and polish the hub and de-assembled it completely. I was surprised how small the ball bearings were, I thought the balls would be small on the front and bigger on the rear wheel because of the forces that needs to be transmitted. No. These balls are very small. And luckily I know that there were 9 balls on each side, which limited my efforts to look for the ones which have rolled down from the table right on the Flokati carpet. This was similar to the search for Dr. Livingstone but me, Stanley, I made it finally. I had an even worse Flokati carpet when I was a teenager and I am sure that if it had been stored at my parents home, one would perhaps be able to retrieve today many of my belongings and drugs lost before I came between 18.

Also I thought that the hub would be heavy, but in fact it is the freewheel that accounts for most of the weight. Wow, almost as heavy as a Cervelo project California frame.

Project Galibier – Status Update

Snow, New Year Holiday Season and the family out for figure skating training in Düsseldorf. The perfect time to work on Project Galibier.

In the meantime some more parts have arrived. To built-up an old bike is a tricky thing and I paid the price. Some of the parts I have ordered will not fit on the frame, others fit but don’t work properly. Sometimes I am a loss what to do, but doing a lot research on the web, asking friends for opinion and sleeping it over helps a lot. One needs a lot of patience.

The upper part is my tribute to Euro-cyclism: New,old stock Shimano AX brake levers with white gums and white handle bar tape. I shall never touch this bike without gloves or dirty hands.

To adjust the brakes is a real nightmare and it brings me back to the time, 35 year ago, when I tried that with my first bike. Technology has come a long way and today it is so easy o adjust, say, a pair of Shimano Ultegra 6700 brakes. But Golden Arrow? One hand hold the calipers in place, another one pulls the wire and the third hand tightens the bolt. The third hand? Yes, that’s the problem.

But the result so far looks good. I don’t know why, but I always wanted to own a bike with a bullhorn handlebar. It seems so logical for my style of riding. I almost never use the lower part of a drop handle, all the weight, so needlessly attached. And of course, I like the design, it looks so much more sportif. Vintage fans will kill me most likely for that, but never mind.

Here we can see thee historically correct setup (except for the wheels). Shimano Golden Arrow front derailleur paired with a Golden Arrow crank set and chain rings. Beautiful – also with the label „12 vitesse“. The bottom bracket which you cannot see is from Shimano as well, but brand new. After I assembled everything I found out that the chainline is not correct. The smaller chain ring is too much on the inside so that the front derailleur position does not match. I will need to de-assemble everything again and buy a new bottom bracket with a longer axle. Paid.

Again beautiful and historically correct. Golden Arrows shifters (although on later Shimano 600 sockets) and Golden Arrow front brake. A nightmare to adjust. Brakes poorly, compared to today’s standards. Still not sure about the correct wire routing. But it looks perfect and nice with the chrome fork and the Peugeot pantograph on the crown.

The Gravity Zero wheels look nice but I am still working on the pair of Maillard 700 hubs. I gave up to remove the cassette and asked the bike shop to do that for me. Then I will order spokes and new rims for clincher tires. Old tubular tires are just to messy.

I couldn’t resist to buy this brand new Charge Spoon saddle. Design-wise it fits perfect and apart from the chain, tires, the spokes and the rims it will be the only new part on the bike. It is also cheap but then it is only artificial leather. Please also note how the seat stem is fixed in the frame: This is a quilted stem and the nut for adjustment is located just below the saddle.

All of this takes a lot of time. I was working in the garage yesterday night and when I looked at the watch it was already past midnight. But it’s fun and I hope that spring arrives soon and the bike will be ready.

Minus Fourteen

That was the temperature in Bremen when I checked the weather forecast before I left for work. 


Nevertheless I opted for Bad Boy to take me to the university where I arrived much later than usual because I had to ride slow and carefully over large patches of exposed ice on the road. That is still much better than being left stranded at Frankfurt or Heathrow airport. Winter salt is now much in demand but also useless at this temperatures to unfreeze the ice.


My Assos early winter gloves are also now useless: Being designed for down to six degrees plus, their protective value doesn’t last for the 15 minutes ride to work.


Surprisingly enough the German postal system is still working and another batches of parts for the Galibier project arrived on Sunday and today.


I cheaply bought a set of wheels, consisting of Maillard 700 high flange hubs and Mavic rims with glued-on old tubeless tires. I am not a big fan of tubeless tires, to cumbersome in event of a puncture on the road, so I completely de-assembled the front and rear wheel. Then I de-assembled the front wheel bearings. There were only eight balls instead of nine on one side of the bearing so I will need to look for an replacement. Nevertheless I greased the bearing and started to polish the chrome of the which now looks pretty good. Supported by a red rubber bear.



I will buy some spokes and a new rim and try to built my first wheel. Well at least I will give it a try and complete it as far as I can but most likely the truing needs  to be done by a pro from a bike shop.


The same for the rear hub. The spokes on the side of the cogs couldn’t be removed so I cut them with a cable cutter. Then I went to the local bike shop and asked them to remove the cassette, which is old-style, screwed on cassette with integrated freewheel. They gave me a big laugh and told me that it is impossible to remove the cassette without the complete wheel: Opposed to modern cassettes, where only the last and smallest cog is screwed on to hold all other cogs in place and where you need to counter the against the stripping tool with a chain whip on any other cog, here need to unscrew the complete cassette with the freewheel that is screwed as one piece on the hub. So you need to counter with the lever of the rims. So it could very well be that this hub will never be usable any more at is neither possible to put new spokes in nor to remove the cassette. I should have read the Sheldon Brown advise before starting where all of this is described in detail. So let’s see if I perhaps cannot find another way.



By the way, this thing is pretty heavy, perhaps more than a set of lightweight wheels.


I also have now a almost new Shimano 600 Arabesque front derailleur. Design-wise that was my first choice for the Galibier and I am happy that I could buy one rather cheaply. I still need to de-assemble, grease and polish this baby. These derailleurs are still working friction-based and not indexed so it depends on the rider to adjust it properly while riding. It can be used with index shifters nevertheless, so I will have a wide range of options. I will probably end-up with a strange mix of components, so the re-sale value of the bike will be rather low as real connoisseurs will not be interested. But I would like to use the components I think will look best, regardless of epoch-correct assembly.



During assembly I found out that I am really a poor mechanic. For me, perhaps because of my academic-theoretical background, if a problem is intellectually solved, I am not much interested in the implementation. I guess my marriage may serve as a prime example. I am getting really impatient when the bloody handle bar can be fiddled around the bloody handle. Or the rust cannot be polished away on the hub. So perhaps by doing this kind of mechanical work I can learn to become slightly more modest, patient and thereby by also nicer to my wife.

The question is, will she be nice to me, when in due time even more nice bike that bought will arrive on our door steps. Ah, the temptations are so big in Germany and the winter is so long. So I better start working patiently on this beautiful piece of Shimano 600EX Arabesque rear derailleur. Again, this one was produced between 1978 and 1984, as the FD. The cage is open, so it is possible to remove the chain from the derailleur without opening the chain. I am not sure what this is good for, but I like this small, useless engineering details.


The Galibier, however will need some more time. I will keep posting pictures 
of it’s progress.

35.000 HITS

I just checked that we have almost achieved 35.000 hits on the Clustrmap counter. Which is much, much less than the reported hits on site traffic, but as an engineer one has to stay on the safe side of the equation. I am really happy to note that the blog is doing so well and there is so much interest in the now very diversified posts.
0 – 5.000 hits from 14.11.07, the start of the site to 26.09.2008, 316 days,

With all the snow in Bremen I thought it nice to start the workday with reading the appropriate blog. Which in this case is „Up in Alaska„.
I haven’t accessed the site for quite a while, the thought to do so naturally occurs in winter only. So I was shocked to read that Jill, the blogger, has moved on to Montana.

Winter Goals

The morning after another day with heavy snowfall in the Bremen flatlands.

On Monday the sky was blue and the roads were dry so I took my Cervelo out of the garage for a 80 km standard spin. I made it just up to Worpswede, about one hour, when it started to snow again. There must have been some very well blue-camouflaged snow clouds somewhere up there. I had to ride about 25 km back to Bremen against the snow and the roads were slowly becoming white. The snow was rather dry and while there wasn’t sufficient quantity accumulated on the surface, it formed in small hurricane patterns. When I came home it was snowing heavily and when I left for work an hour later on the Gazelle, I was hardly able to steer through the snow.

I rode to work early in the morning the next day on the Gazelle through the snow. It is a little bit tricky to ride on a racing bike with 700 x 23C tires as every little bump below the snow forces a sudden and unexpected change of direction. I thought it as a good exercise to learn how to control a slippery bike. I was probably just thinking that and how great I was handling the steering already and how fast I could go, when I came to a crossing where I had to brake a little bit harder. I did it too hard, so that the rear wheel went to the right and me down hard on the road.

After that I thought what a bloody stupid prick I am. I am not 26 any more when I rode home in the rain on my Motebecane on a bicycle lane than was separated from the pedestrian walk by a line of randomly spaced bollards and I crashed directly with my right knee into one without seeing it. That hurted very much but I survived, nothing was broken and there were no consequences at all. Now I am 48 and every time I fall it takes weeks until all of the pain is gone and I really should consider this when making cycling decisions.

So after spending a day in the office, trying not to move at all and after another night at home, trying not to move as well, I went into the garage and refitted the Bad Boy with the winter Schwalbe tires (700 x 30C). I was reluctant to use Bad Boy in the winter, first it is very messy to clean the bike, second the paint is very sensible to scratches (strange spec for a MTB or urban hybrid) and third it has no mud guards. And forth, the last time I crashed really hard was riding down from Yabistu Toge to Hadano on Bad Boy with winter tires.

But winter in Bremen leaves me no other choices than to ride on fat tires:  The Bad Boy was placed just behind the Cervelo and the Gazelle and the electric shopping bike of my wife and the new green Giant of my son and the Peugeot Galibier frame I am working on. Which stands in front of the old Pinarello frame which I am polishing and the beautiful Peugeot I have bought recently for fun and just leaves enough space for this super cheap Pesacarola racing bike I incidentally bought and the beautiful Gianni Motta I could not resist to buy. If performance really depends on the number of newly acquired bikes, I should be ready for Paris – Roubaix.

In other words, I took me some time to get the bike out, mount a saddle, pedals, tires, saddle bag, speedmeterand lights, which took another half an hour. All of this for 15 minutes of riding to work.

After having done the commute now three times I have to say that it is actually much more fun than on a racing bike. It is also stimulating not to been overtaken by grandmothers on their sturdy Holland-bikes while trying to stay upright on the Gazelle.

On the weekend I will utilize my newly rediscovered cycling courage to ride through the white planes on the Bad Boy.

And after coming home an having enjoyed a cup of hot instant coffee, I will go to work on the Peugeot Galibier frame. I am still waiting for parts to arrive at my home and I am excited how some of the purchases, like the charge saddle, the Maillard 700 high flange hubs will look like. Although I have to admit that assembly of a bike is a tricky business, even if one has most of the tools. I wasn’t able to remove the crankset covers from the Pinarello frame and had to ask for assistance at a bike shop. I am also not able to mount the Shimano 600 rear tube shifters properly. And it was an absolute nightmare to fiddle white handle bar tape around a bullhorn handle bar. Well, this must be the fate of the Euro-cyclist, I guess.

I will post some pictures once the wheels have been mounted.
Meanwhile have fun in the snow, if you have snow.

Shimano Golden Arrow

There was a time not so long ago, when the rank order was not Dura Ace, Ultegra and 105, followed by names serious cyclists spell with the same intonation as „leg cramps“ or „Daily Yamazaki“. Yes, that was the time of Dura Ace, 600 and Golden Arrow. Golden Arrow was the lowest (serious) road racing group set produced by Shimano between 1983 and 1986. 


Still I believe it is one of the most beautiful designs done by Shimano ever. An arty touch, but not too much, so much nicer than the apparently pure functional parts of today. Although, while writing this I think of these ugly Hollowtec crank sets of Shimano from today.


Of course, if you really love to have pieces of art on your bike, the Shimano Arabesque series is even better. Unfortunately it is politically incorrect to use them these days. If you are more interested in such details, there is no better place to look than Velo Base , but be careful, if you like that stuff the site is highly addictive.


I was looking for some old parts to built up the Peugeot bike under the working title „The Galibier Project„. I have spend thousands of Yen for bike mechanical services, mainly with Nagai-San from Positivo and given the long winters in Bremen I thought I could learn to do this as well. I think this is a habit of people lively in harsh environments and  I am just happy that I don’t have to polish and paint wooden nutcrackers.


For very little money (less than 700 Yen, to be precise) I bought a pair of shifters, a front derailleur and a rear derailleur for the Galibier. The parts were anyway in good shape, but nevertheless I spend some time to de-assemble them, clean each of them thoroughly, greased and oiled them and assembled them back into shape. They still looked used, but for me they are fine enough.


The wonder word in vintage cycling is: „N.O.S“, meaning New, old stock: spare parts that were never used before but produced in the seventies or eighties and kept in stock somewhere when inventory level was not equal cash flow equal financial performanace equal quarterly report for the share holders. I just bought another set of Shimano 600 AX shifters in NOS conditions. Not sure what I will do with them but they were too cheap (550 Yen) and too beautiful to be ignored.


These are racing components from the first aerodynamic-crazed wave, long before Cervelo jumped on the train and compared aerodynamic adavantages against weight advantages. 35 seconds overall on one of the hardest stages of the Tour de France for an average rider. Thank you very, convincing. Already in the eighties components were constructed in such way as to produce minimum drag. My Golden Arrow shifters, for example are located on a clamp above the lower tube instead of left and right on the lover tube for precisely that reason. 



An even better example to eighties aerodynamic design are the Dura Ace AX brake calipers which sell today in the range of 20.000 to 60.000 Yen a pair.


So I will continue for a while to buy stuff here and there and hope that I will be able to learn to fit all pieces of the puzzle together in the garage later.

I also bought a nice piece of tableware from the Edo-period while visiting the Maeda mansion in Komabatodaimae with Juliane some time ago. On the left we see a cyclist engaged in stretching exercises for the forthcoming stage of the Transalp, while his wife to the right is urging him to stay home and play with the kids. Heartwarming.

Transalp 2011

Done. David and me succesfully registered as team Positivo Espresso 1 for the Transalp 2011 race. A confirmation e-mail from the organizers came in just seven minutes ago. We are still awaiting confirmation for our (second) team Positivo Espresso Europe, consisting of Juliane and David J.

Details about the race can be find here. In brief: 7 stages. 936 km. 20.000 meter elevation difference. More difficult than the Yamanote challenge. Jerome and Juliane in 200?. David and Jerome, Juliane and David in 2009. David and mob, Juliane and David in 2011.

De facto the European home race of the club.

Ups, I should start to train but it is already dark and minus eight degrees outside.

Peugeot Galibier

Steelframe, Reynolds 501 tubing. About 20 years old but still in mint conditions. This will be my winter project and I will try to built up a complete bike with used parts. As temperatures are down to minus nine today that sounds like more fun than riding. And perhaps a more meaningful activity than traveling to London to see Peter Pan.

Winter Ride

I was leaving the house at noon after spending the morning checking the complete flickr photo account of Tom for pictures of fur coats. To my excuse I have to say that there is very little else one can do in Bremen in November when temperatures had dropped down to zero degrees.


Nevertheless I prepared myself for a short winter ride. The words „preparation“ and „short ride“ and their relation to each other change completely over the seasons. In summer the duration of a preparation is about 15 minutes and consists of putting on socks, heartbeat monitor, bib shorts, jersey shoes, gloves and helmet (in that order. I try to avoid looking into a mirror when having only socks and heart beat monitor on) then running back to the house to collect the water bottle, running back again because one has left the camera, then cursing and climbing back up the stairs to look for the map, thus filling the required 15 minutes interval. This is then followed by rides of eight hours plus, as long as the sun is visible in the sky and in Germany during the summer than can be a damn long time. There is much more enjoyable riding time compared to less enjoyable preparation time.


In winter, on the other hand, the preparation time is endless. It starts with the pounding about the right choice of attire. Lately I have been reading something about how PE members laughed about overdressed, sweaty winter riders they encountered on their trips and that left me now as a nervous, neurotic wreck shortly before every ride. Am I overdressed? Will somebody laugh at me?  Shall I sell my yellow Assos Fugu Jacket? As if there were not enough issues already, I have always cold feet. So I started to use two layers of shoe covers. One neopren type just over the Shimano MTB shoes and another wind stopper like material on top. The neopren type shoe cover was cheap and I bought it at Rose, the favorite shop of Ludwig and myself. I shouldn’t really complain about them and it is certainly not in my interest to vituperate about Rose. But today I needed close to 40 minutes of preparation time and a large chunk out of that time was consumed by trying to close the zipper on the backside of the shoecovers. As this can only be done when the shoe covers are on, my neighbors saw me winding on the road in all kind of poses, commonly known from 12 year old Romanian girls engaging in rhythm sport gymnastics.
After I have finally managed to zip up both shoe covers I was seriously considering to keep them on until the next ride. Sleep with them, shower with them, walk around in holy academia …. everything is better than to put them on one more time.


And after endless 40 minutes of preparation, how long did I ride? 3 and a half hours. This relationship is sadly distorted. Coming home, I needed time to shower, redress, eat, drink some coffee, again valuable time spend. 5 hours bike related activities, not much riding thereof.

I choose a longer standard route today, along the river Wuemme (the Tamagawa equivalent) as usual but then further on to Lessum. There weren’t much bicycles on the road but quite a few people have opted to take a walk. I hit a cobblestone section of the road that was lying in the shadow of some trees and immediately the ride got wobbly and I almost fell down on the slippery surface. From then onwards I rode very carefully, checking the surface for spots of black ice and keeping speeds down. Now all the leaves are gone and it is more fun to ride on the bike paths as they are cleared of all obstacles. I rode on to Ritterhude, one of the few places that provides something like „hills“ and I climbed about 50 meter elevation difference as a preparation of the Transalp. The further on to Osterholz-Scharmbek where I took the obigatory SOS landscape photo, and further on the Worpswede on the standard loop. My average speed was down to 25 km/hr and I am not exactly sure why. Sure, there was some headwind but overall it was just difficult despite keeping the heartrate in the 145 – 155 bracket. 


The road from Worpswede to Quelkorn was just boring as usual, I really don’t know why I am riding there. Fischerhude to Borgfeld in contrast is quite nice but I was quickly running out of steam. I had no food with me and when I tried to drink from the water bottle I noticed that the nozzle was frozen solid.  My Ciclo device showned now minus degrees and my feets and my hands were iceblocks. Just four days ago I visited in a university excursion I huge German fish monger called „Deutsche See“ and we were shown arround the cold storage facilities, minus 24 degrees…. that was really cold. But today on the bike didn’t felt much better. My thoughts were running around…..a tune popped up in my head, first „Walk Hard“ by Dewey Cox and I could imagine this conversation from the trailer going on between my body and my mind:

„So maybe you don’t believe in me after all?“
„I do believe in you, I just know you’re gonna fail!“ 


Gazelle, leaning against a gate. Variation of an old theme.



Then I was again on the river Wuemme and after crossing the railroad line and after making a turn a Riensberg graveyard I was back at the house. 82 km only, time outside the house almost equal riding time. Too cold to make a break. By the way, to opt for the lighter Assos air jacket 851 with some uniqlo heatec trikot below was perfect. I need another pair of shoe covers, some overgloves and an hour more time for preparation though.

Proven ways to improve performance levels

Lately, mainly because I am focused now on academic achievements rather than physical ones and perhaps because it isn’t much much to ride a bike on wet roads, under grey clouds, threatening to pound merciless tons of icy water on barely prepared riders in minus temperature. And all of this in the flat lands of Bremen and its surrounding. I had to think of ways how to get back into better shape and survive the winter season.


Veteran riders know that there is one method commonly applied when performance levels are following the function curves of y (level) = 1/x(time). The nice thing about this method is, that you don’t need to overdo yourself on the bike, something that is rather unpleasant as described above. It is very simple: Buy a new bike. And what can be more pleasant to buy a new bike in the country of Germany where it seems that every cellar and every attic is filled to the very top with vintage frames from Italy, France and England. I am not a big fan of petroleum-based frames, even my dear aluminium Cervelo is out of favor in the harsh environment of North Germany. However the Reynolds 531 tubing of my Gazelle is performing well. So I thought that I need something similar. Now here it is:

First ride, properly dressed up in Japanese construction worker pants.



A beautiful Peugeot racing bike from the seventies in grey, pimped up with some orange accents in the form of Schwalbe Ultremo tyres and new orange handle bar tape. Everything else is right from the original bike: Mafac brake levers, Huret derailleur, Suntour shifters, Maillard high flanged hubs …… 



This is just perfect to cruise around in the old streets of Bremen, parking in front of the city hall dating back to the 16th century or paying a visit to a friend living in an rundown art deco villa from the early 20th century.

And it is also perfect for the challenges that area awaiting me in 2011, in particular for the Transalp. David and me are pretty much ready and excited to sign up in December 1st for the event. I need a good bike to bring me over the alps and I thought a triple crank set would just be what I need to speed up the 20% slopes in Austria and Italy.


Of course this bike is much to beautiful to be ridden. It will be stored in our garage under a black tarpaulin and I will dare to take a look from time to time. In the meantime the Gazelle has to bear the brunt of snow, ice and rain in Bremen.


Some more bike porn pictures from the seller, a vintage pro shop in Muenster. I exchanged the tires and the replaced flat bar with the original drop handle.
