POC 2015

POC race day mips octal aero clothing koroyd (8)

When POC first stepped into the road bike space, their focus was all about rider safety while on the road. Their AVIP line touted special attention to details that would increase Attention, Visibility, Interaction, and Protection of the rider. In 2015 the AVIP line has not gone away, but it is joined by a new collection – Raceday.

Raceday is exactly as it sounds, a full kit designed specifically around going as fast as possible. Racing is usually done on closed courses so POC can instead focus on cheating the wind and creating designs that will make the rider faster rather than more visible to drivers. That isn’t to say that the Raceday line isn’t just as safe though – you’ll find much of the same rider protection as the rest of the POC line. Much of the new technologies come from their partnership with Garmin-Sharp, Volvo, and the wind tunnel gurus in their own WATTS lab in order to create the smartest pieces possible.

Find out why the Raceday collection is more valuable to racers than an aero bike after the jump…

Side by side, the difference between the AVIP and Raceday line is clear. Put the two on a dark road out in the countryside and you will see the Avip collection long before you spot the muted colors of Raceday.

But Raceday is more than just new colors. Through their work with the WATTS lab the line has seen extensive aerodynamic tweaking to offer a complete aero package. Each piece is designed to work together with special fabrics in place where the POC Tempor helmet would rest over the jersey, or different fabric orientation from the front to the back, on the sleeves, etc. The various Raceday pieces fit into the POC aerodynamic design levels with level 1 offering maximum advantage from wind tunnel testing and CFD analysis like the Tempor and the Octal Aero, to level 3 which was designed with aerodynamics in mind, but not the primary focus like socks and bottles.

Why does all of this matter? To show just how important aero clothing can be, POC used their findings at the WATTS lab and their work with Garmin-Sharp to put together a chart of the different methods to decrease drag on a bike. Listed from most effective to least, the chart also analyses the cost per second saved. As you can see above, a skin suit is not only more effective in decreasing drag than an aero frame and aero wheels combined, but it is one of the cheapest ways to get faster. Basically if you’re riding an aero bike and wheels but wearing ill-fitting jerseys, you’re doing it wrong.

Raceday also integrates smart technologies like silicone wrapped yarn that is woven into the fabric to create leg grippers that grip without decreasing circulation. We’re happy to say we’ve seen similar grippers on other company’s shorts, since they feel fantastic. In the jerseys you’ll find fabric that is designed to capture sweat and turn it into a cooling vapor against the skin for improved thermoregulation.

The Raceday color story continues across the line in typical POC style. New colors for the Octal include Hydrogen White, Granate Red, Nickel Blue, Flourescent Pink, and Garminum Blue.

In addition to the Raceday collection, POC has introduced a new line of shorts and tights that will include VPDS chamois that uses technology based on their Visco-Elastic Polymer Dough found in their body armor. When placed in the chamois, the VPDS inserts both support the rider and absorb impacts and won’t break down over time.

Depending on the chamois, the inserts use different shapes with the high end pre formed Contour chamois using an insert that keep the rider in an aerodynamic position by leaning forward slightly. The various chamois will be found throughout the short and tight line signified by the name, e.g. Contour Bib Shorts.

As one of the newest additions to the AVIP line, the Backprotection Jersey takes road apparel to the next level in protection. Exploring the benefits of Koroyd (the same material found in Smith’s helmets), the jersey uses a removable spine protector that is still breathable. Chances are good that the design will change slightly before production, but the concept will remain the same.

Of course, the Octal is now available with MIPS protection as we reported earlier.

POC was also showing off their Eyepark system which uses two magnets to quickly stash your glasses when you need to see the road in a tunnel, or other low light conditions. We learned that while 2015 will involve external magnets attached to the helmet and glasses, 2016 helmets will have the magnet built in.

Finally, there are a few new sunglass models as well.

Optimizing Tire Tread

Nach meiner etwas harschen Kritik an Jan Heines Beitrag zum Thema „Je suis Charlie“ als Ausgleich einer der wirklichen guten Beiträge aus seinem Blog „off the beatne path“ zum Thema Radreifen.

via off the beaten path

Compass_tread_pattern

Most tire manufacturers agree that supple sidewalls and a thin tread make a tire fast, but the role of the tread pattern remains poorly understood. Most modern tires have either a completely smooth tread (slicks) or a coarse tread pattern similar to car tires. Many high-performance tires are smooth with just a few large sipes. None of these tread patterns are optimized.

Car tires have tread mostly to prevent hydroplaning. With their wide, square profile, a layer of water can form between tire and road surface. The tread pattern forms channels so the water can be pushed out of the tire/road interface.

Bicycle tires do not hydroplane. Their contact patch is too small and too round for that. This means that car-inspired tread patterns are not necessary on bicycle tires. Does this mean that no tread pattern at all – a slick tire – is best? Any tread pattern reduces the amount of rubber on the road surface… In the lab, it does work that way: Slick tires grip best on smooth steel drums.

Real roads are not as smooth as steel drums. An optimized tire tread interlocks with the irregularities of the road surface to provide more grip than the pure friction between asphalt and rubber. This is especially noticeable in wet conditions, when the coefficient of friction is reduced by half, yet you can corner with about 70-80% of the speed you use on dry roads. (Unless the road surface is greasy…)

The ideal tire tread has as many interlocking points with the road surface as possible. The “file tread” found on many classic racing tires does this. The ribs are angled so they don’t deflect under the loads of cornering or braking.

Why do race cars use slick tires, and not a file tread? The reason is simple: It would be abraded the first time the car accelerates. However, bicycle tires don’t wear significantly on their shoulders – the part that touches the ground when you corner hard – so we can use a tread pattern that is optimized for grip without worrying about wear.

Each Compass tires has three distinct tread patterns, each designed for a specific purpose.

  • Center: Fine ribs serve as wear indicators. When the lines disappear, the tire is about half-worn. (The tread of our narrower tires is not wide enough for ribs, so small dots are used instead.)
  • Shoulders: When the bike leans over as you corner, the tire rolls on it shoulders. A chevron or “fine file” tread pattern optimized grip.
  • Edges: This part never touches the road (unless you crash). They serve only to protect the casing from punctures, so they don’t need any tread.

TireProfile-hi

Supple casings make tires faster, but a supple casing is of little use when it’s covered by thick tread rubber. The fastest tire would have just a minimal layer of tread rubber, and many “event” tires are made that way. Unfortunately, that means that they don’t have much rubber to wear down until they are too thin to use. At Compass Bicycles, we call these tires “pre-worn”.

Compass tires have a slightly thicker tread in the center. A little more material there doubles or even triples the life of your tire, while adding minimal weight and resistance. (On our widest 650B x 42 mm tire, the added tread weighs less than 50 grams.) Once you have ridden the tires for a few thousand miles, they’ll be as light as the “event tires”.

On the shoulders and edges, the tread does not wear. So we made it much thinner to keep the tire supple and reduce its weight. The tread extends far enough down the sidewall that the casing is protect when seen from above. Extending the tread further adds little protection, but makes the tire less supple and thus less comfortable and slower.

tires_comp_650_42

Another important factor is the tread rubber. This is an area where incredible progress has been made in recent decades. In the past, you could either have good grip or good durability. I used to ride Michelin’s Hi-Lite tires, which gripped well, but rarely lasted even 1000 miles (1600 km).

Compass tires use Panaracer’s best tread rubber, which is amazing. Our tires are among the grippiest you can find, yet I just got an e-mail from a 230-pound rider who got 3786 miles (6093 km) out of a set of our 26 mm-wide Cayuse Pass tires. The wider tires spread the wear over more rubber, so they last significantly longer. (Don’t try to set wear records, but replace your tires once they get thin. The risk of flats, or worse, blowouts, is not worth getting an extra few hundred miles out of a worn tire.)

Tread color is another important consideration. Modern colored treads no longer are the “death traps” they used to be, but especially in wet conditions, the grip of tires with colored treads – including the Grand Bois Hetres we sell – is not quite as good as that of black treads. That is why we offer only black tread.

Die Geschichte der SB.

via Cycling Tips

Sunglasses have evolved from a humble yet essential piece of protection in the cyclist’s kit bag to an expensive fashion statement. Dave Everett and Wade Wallace look back through the archives to find some of the more memorable and outlandish examples of cycling-specific eyewear that we’ve seen in recent decades.

The first use of sunglasses in sport dates back roughly to the turn of the 20th century. Long after God invented bicycles was the creation of dirt, grit and flies. Man found it necessary to shield the eyes from the ocular problems that could occur from such things.

The flying goggles and eyewear that were donned in the early days of ‘fast-paced transport’ were adopted by cyclists who were tackling the then-unpaved roads. Large ex-military flying goggles made of glass and leather were the choice of such early tour champions — riders like Octave Lapize, Phillippe Thys and Ottavio Bottecchia all could be seen racing to victory in such eyewear.

The goggles style eyewear from the classic 1920's (Vervaeke and Geldhol smoked the cigarette.)

It wasn’t until the 1950s that eyewear that we’d now recognise as sunglasses was first used in the peloton. Until then the flying googles were still used but modified — rubber replaced leather and frames became lighter.

Persol and Ray-Ban were at the forefront of lens and frame design at this time and sunglasses had become fashionable as film stars made them popular.

With new materials being used — such as nylon and silica — you’d think that glasses would have been on every face in the peloton. The champion of champions Fausto Coppi used the lightweight and popular Aviator; being Italian he pulled off the film star look without a problem. But he was one of only a few in the peloton at this point.

Fausto Coppi was one of the first to don the aviator sunglasses

The flying goggles look was slowly disappearing from the peloton and, partly due to roads becoming better paved, cyclists were seen using sunglasses.

There were several riders that still went against the grain though. Dutch Tour de France winner of 1968 Jan Janssen was one. His reason for wearing glasses was not to look cool or to keep the grit out of his eyes, but because he was short-sighted.

1974 Tour de France winner Jan Jannsen, pictured left with Eddy Merckx.

Even through the 1970s and into the 1980s, it was largely only the guys who needed proper spectacles that were seen racing in them. Laurent Fignon, or “The Professor” as he was nicknamed due to his spectacles, was one of the few. Right through his entire career, from 1982 until 1993, he could be seen sporting his rounded spectacles.

Archieffoto's Cor Vos

It wasn’t until companies like Carrera started developing skiing goggles that things got exciting. Since 1956 Carrera had been making glasses but the inclusion of thermo-plastics and interchangeable lenses helped with the boom of cycling-specific glasses. It was one guy and his dog that really changed the face of sports optics though. The man was Jim Jannard and his dog was called Oakley.

Jim started out in 1975 by making and selling motocross and BMX grips. After success with grips he turned his attention to goggles for MX and BMX. Then in 1984 the start of what we can now call performance eyewear hit the market. That was the time of the Oakley Eyeshades.

While some riders were using aviation-type glasses, Greg Lemond debuted the Eyeshades. He’d purchased them himself then later, before the Tour de France, he contacted Jannard to get a few extra lenses. From that point on Oakley became a firm part of road cycling culture.

In 1985 Lemond and Phil Anderson were the first official Oakley athletes in the peloton. The huge lens and bright colours stood out and with prototypes such as the rip-off lenses that Anderson used in Roubaix it wasn’t long before they grabbed people’s attention.

Untitled-3

Come 1987 and half the peloton was wearing Eyeshades. The Tour that year saw riders harassing Jim for a pair — they were a must-have item.

glf-eyeshades-85

Oakley weren’t the only ones at this point attempting to break into the cycling and sports scene. New brands were popping up to take on this market. Briko and Rudy Project and even French manufacture Look all had a background in snow sports, and they all entered the sports glasses market. Some succeeded while others fell by the wayside.

People didn’t just want to look the part and to have quality optics; they wanted to be part of a brand. Along with either being a Campag or Shimano rider you were now either Euro chic or American cool dependent on your eyewear choice.

Development rolled along pretty quickly from this point thanks to the introduction of new lens tints, interchangeable lenses and new frame materials. Briko entered the market with insect-eye-inspired designs while Oakley developed the integrated prescription lens on a curved surface. This meant the likes of Alex Zülle, with his bad eye sight (and poor descending skills), no longer needed to look quite like the librarian of the bunch.

Untitled-2

Back in the early 1990s, if you thought yourself a sprint ace or Classics contender you’d probably be going for the Briko Shots — a multi-coloured and swivelled-armed affair. Franco Ballerini and Mario Cipollini made them look cool, even with the latter’s lion’s mane.

If you weren’t the build of a sprinter you could always look towards Marco Pantani and his stylish Briko Stingers.

Not a fan of the Italians? Prefer a bit of old-school German? Best to choose the Rudy Projects Noosa. Behind the lens you could hide the pain of pushing a huge gear just like Jan Ullrich.

Untitled-7

But Oakley has always been the brand in the front seat with regards to style, development and advertising. Sometimes they got it seriously wrong though — just look at the Over The Tops from 2000. Were they simply a marketing stunt or was Oakley genuinely trying to change what sports sunglasses could look like? Who knows. Either way they suited their name but never stood the test of time.

David Millar (left) and Frank Schleck (right) sport the aptly named Over the Top glasses.

Lance and his army were the pin-up boys for Oakley in the mid 1990s and right through until they all retired (or got bust). M-Frames were the item all self-respecting cyclists wanted to own. Or if you were a hard-man, the Racing Jackets that George Hincapie seemed to have 1,000 pairs of in fancy paint jobs were also a good option.

Untitled-8

Huge brands like Specialized and Giro attempted to enter the dog fight of selling glasses, but found it far to hard to get a large enough market share to warrant continuing.

Specialized made a brief foray into the sunglasses market, releasing the Specialized Miura as worn by Philippe Gilbert and Tom Boonen here.

Of course, we’ve seen some interesting (and sometimes questionable) developments in sunglasses in recent seasons as well. Ryder Hesjedal made waves with his Poc glasses in 2013 and whether you love or hate them, you have to admit they got people talking.

Ryder Hesjedal introduced POC's disco-inspired eyewear to the cycling market. He is pictured here in the 2013 Tour de France wearing Poc's DID shades.

Earlier this year Oakley released its Heritage Collection to celebrate 30 years of making sports eyewear, with Eyeshades, RazorBlades and Frogskins among the models to make a return.

Yoann Offredo was spotted at the 2014 Milan-San Remo wearing some Vintage Collection Eyeshades.

Other notable brands in the modern pro peloton include the Zero H+ shades worn by recent Vuelta a Espana winner Alberto Contador:

Untitled-10

And the new Bolle 6th Sense (not yet released to the public), as sported by Simon Gerrans in Canada recently:

Gerrans_Quebec14

Another yet-to-be-released model is Oakley’s Jawbreaker, a successor to the ever-popular Jawbone. The Jawbreaker has seen a few public outings this year, including in Mark Cavendish’s short-lived appearance at the Tour de France:

And for something a little different, look no further than Giro’s Air Attack aero helmet which has a magnetically attached “optical shield”:

Garmin-Sharp used Giro helmets until they changed to Poc in 2013.

Lens shapes, optical clarity and frame materials have all been refined and developed in recent years. But what can we expect next? It would seem sunglasses are going high-tech.

You can already buy glass with built-in cameras, perfect for filming crazy car divers in action, chopping you up. Could we see this technology develop to the point that we’re able to watch races from the point of view of the riders? It’s hard to see why not.

We’ve already seen the release of the Recon Jet glasses, which feature a heads-up display and can show you speed, distance and cadence all right in front of your face. Google, too, has its Glass project, which will make it possible to have all the whizz-bang tech of an iPad within sight at all times. Maps, how to swear at the Italian driver cutting you off, the number of kilometres until the nearest coffee shop — a whole range of data will be available to us, all via our eyewear.

Image: Recon Instruments

But is this what we want? Or do we just want a good looking set of shades so we can look the part when sipping our lattes or suffering in the bunch? I guess that’s down to personal preference, but either way, the long and colourful relationship between cycling and sunglasses certainly isn’t going to end any time soon.

What have we missed? And what are your favourite cycling sunglasses of all time?

Festive 500: In Schweden

Manchmal, wenn ich mich zwischen Weihnachten und Neujahr auf das Rad gequält habe und in dem sehr bescheidenen Wetter um Bremen gefahren bin, habe ich die Unfairness bejammert, die es Teilnehmern in, sagen wir mal Australien oder Südafrika, so einfach gemacht hat, die 500 Kilometer abzuspulen. Bis ich diesen Bericht über die festive 500 in Schweden las.
