James Huang, technical editor Slipstream riders used two versions of Zipp’s new Powertap-equipped disc wheels. James Huang, technical editor Zipp will offer its new PowerTap-equipped rear disc in both its new Sub9 shape… James Huang, technical editor …as well as a fully flat disc for riders that prefer a stiffer feel. James Huang, technical editor Naturally, both wheels get the full dimpled treatment for which Zipp has become well known. James Huang, technical editor The prologue was reasonably technical but riders were still using 21mm tires in search of more speed James Huang, technical editor Slipstream’s Felt DA machines include neatly routed cables that keep them out of clean air. James Huang, technical editor Corima carbon-specific brake pads are still a popular choice among the pro peloton. James Huang, technical editor Zabriskie’s spare bike was topped by this custom-covered fi’zi:k saddle. James Huang, technical editor Several Slipstream guys slapped fi’zi:k’s ‘extra grip strip’ appliqués on their saddles James Huang, technical editor Yikes, that’s a narrow setup! James Huang, technical editor Zabriskie warms up before his start. James Huang, technical editor Team CSC will ride Cervélo P3C bikes again this season. James Huang, technical editor 3T is a new sponsor for Team CSC and team bikes were fitted with the new Ventus LTD aero bar. James Huang, technical editor Not much frontal area to look at here! James Huang, technical editor Surprisingly, team Cervélo frames were also fitted with 3T forks instead of the stock Wolf models. James Huang, technical editor 3T claims its Funda fork blades offer an aerodynamic advantage thanks to careful shaping. James Huang, technical editor CSC is also using 3T stems… James Huang, technical editor …but not on all of its bikes yet. Some riders need special sizes which 3T hasn’t produced yet. James Huang, technical editor FSA still supplies the team with its cranksets which neatly round out the Dura-Ace drivetrain. James Huang, technical editor CSC’s cables aren’t quite as tucked away as Slipstream’s but are still held tightly against the stem James Huang, technical editor Trek claims that its Equinox TTX frames are some of the most aerodynamic around James Huang, technical editor The ‘grooved’ top tube supposedly imparts additional stiffness to the frame. James Huang, technical editor Astana is using a mix of rear discs, such as this Lightweight model covered by Bontrager decals James Huang, technical editor Bontrager’s Aeolus ‘triple radius’ discs were still in heavy use on the team. James Huang, technical editor The Trek Equinox TTX also incorporates very neatly tucked away cables. James Huang, technical editor Rock Racing was supposed to be riding DeRosa frames James Huang, technical editor
