I just checked that we have almost achieved 40.000 hits on the Clustrmap counter. We are again picking up speed as you can see from the data below:
0 – 5.000 hits from 14.11.07, the start of the site to 26.09.2008, 316 days,
– 10.000 hits to 21.05.2009, 228 days
– 15.000 hits to 18.11.2009, 181 days
– 20.000 hits to 21.03.2010, 123 days
– 25.000 hits to 14.06.2010, 85 days.
– 30.000 hits to 24.09.2010, 102 days

What is the most cost-effective way to lower the total weight of your bike? This is a question I asked myself and perhaps some other members would like to contribute as well.
So let’s start with two examples. Two of the components where most of the weight of a racing bike is concentrated is the frame and the wheels.
A typical Cervelo S1 frameset retails in Germany for 126.000 Yen and weights 1.460g (size 56) without fork, head set and other components. Bare frame. The Cervelo S3 frame retails for the equivalent of 470.000 Yen and weights only 1.080g in the same frame size. Thus one get 380g of weight saving for 344.000 Yen of additional cost. Or one pays 905 Yen for every g lost.
Now let’s take a look at wheels. A good standard wheel set are the Campagnolo Zondas which I have been using for years. In Germany they are sold for 45.000 Yen and they weight about 1.550g without quick release, rim tape and rear cassette. If you have the courage (and the body weight) to use them, Mavic R Sys SL provide a lighter alternative at 1.295g for 172.000 Yen. So 255g for 127.000 Yen. Or 498 Yen for every g less.
I am aware that all calculation depend on the starting point (which frame, wheel etc. is your benchmark) and how far you will go. The first g less will cost much less than the last one as well.
But I wonder, is there any component that would stick out? Quick release? Tires? Tubes?
Michelin Airstop Air 1 tube with 40mm Presta valve. 93g for 569 Yen. Continental Race Supersonic Tube with Presta 36 mm valve. 45g for 1034 Yen. Less than 10 Yen per g reduced. Well, but it is hard to shave off more than 100g from the total weight by using different tubes. Or no tubes?
