Olympic Scalpel



WIth only a few weeks before the olympic cross-country race, special bikes and parts are starting to appear. Roel Paulissen just had his olympic bike finished and it's quite a bike as seen in this Dutch article. The all black Scalpel frame looks a bit rough but it's for a good reason.



Carbon frames and parts are usually covered with a layer of 'decorative' carbon (most bikes with an perfect looking carbon weave finish). Also, they often put filler to have a smooth, even finish. While the off the shelf Scalpel doesn't have a cosmetic carbon layer but is rather painted, it has filler to look perfectly smooth. Roel's new bike doesn't. It definitly looks rough but it saves 200 grams on a frame already quite light. The decals will be replaced for the olympic race to match each olympian's country uniform.



What else? The special Lefty has a thinner bottom section, the air filter is gone and replaced by a little tube that sticks out of the boot (lighter but durability takes a hit, pros don't care, consumers do) and the whole thing is tuned to have the Lefty Speed weighing 1020 grams! That's 2.25lbs for you americans, very light!



More details about the Mavic carbon spoked tubular wheels the team has been using this year. The rims have four thin carbon strips to stiffen and reinforce the rim so they can use less alloy. The result is a very strong yet light rim. The clincher rims don't seem to have that feature and are probably more or less the same rims as the production 2009 SLR rims.



Also note the brake adaptor on Jakob Fuglsang's bike: 16 grams lighter each. This should bring tears to the eyes of weight weenies...

That's hot man! I am still a big fan of Cannondale bikes.

Hot bike to drool to indeed, I have always had a thing for all black bikes, I'd just peel off the stickers on the Lefty.

8.85kg/19.5lbs for the whole bike and according to the mechanic, it's quite a durable build, I noticed it doesn't have the FRM stem like the one Roel broke in his crash with Sauser at the Marathon Worlds...
