As in the year before Steffen Wesemann had a special bike prepared for Paris Roubaix. Due to the good dry wether conditions this year it was spared, and Steffen used a bike with standard caliper brakes but not integrated seat post. The frame is more beefy in the front at the head tube box and the chain stay-bottom bracket joint. Remarkably is the chainring combination of 53 - 49 teeth. Cobbles of the order in Paris-Roubaix have a rolling resistance similar to a 4.5 to 5.5% inclined sloop. Pro's would use in a race on a climb like this 53-18, 19 or lesser 21 , but on cobbles it's better to use a more aligned chain line of 49 -16,17 or 18 to avoid that the chain snaps over. A interruption of power leads immediately to an gap and the resistance increases again but if the chain needs to be put back by hand ends up in a chase.
This bike, based on a road bike frame, but with cantie's and a fork with more clearance, has been used a a training bike. He used this bike very likely to get the feeling for the cantie's and the lesser responsive steering. It has the insurance batch which is required in switzerland still attached to the frame.
