This is the ultimate mixed road racing wheelset. It's so fast that we're free-wheeling in the pack, whilst the others are pedalling. Going deeper on the back provides additional aerodynamic advantages, but the shallower front end improves stability. As used in UCI Continental level racing by the Canyon dhb p/b Soreen pro team.Read MoreWe all want to go fast; that was the brief. The latest breed of tubeless tyres give up nothing in weight to their clincher counterparts and the Schwalbe Pro One, that you can have fitted by us prior to delivery, weighs only 250g for a 25mm tyre (290 grams including 40 ml of sealant, while the Continental GP4000SII tyre with tubes weighs 320 grams). The tyre rolling resistance of the new Schwalbe Pro One Tubeless is reduced by 9.5% over their clincher version according to Schwalbe's own tests! Hence tubeless was essential. Going deep is obvious for aero gains, wide rims with a U-profile provide great handling and reduce drag across multiple wind yaw-angles.
