Shimano Ultegra Di2 Components ATTEN CHB-01 Aero Handlebar Physics dictate that aero gains matter most at the front of the bike, so we relentlessly honed every surface of the ATTEN CHB-01 Aero Handlebar, down to its integrated computer mount. Rider-focused ergonomics, ultra-lightweight construction and unsurpassed handling for real-world gains. ATTEN X Scope Artech 6.A+ The ATTEN x Scope Artech 6.A+ wheelset was co-developed with Scope, building on their flagship, WorldTour-proven design. We re-optimized the rim shape for even greater speed on the Nitrogen Pro with 30c tires, minimizing drag and turbulence where it counts most: the wheel-fork interface. Vittoria Corsa Pro TLR 30c The 30c Vittoria Corsa PRO is the tire the ATTEN x Scope Artech 6.A+ was designed with. This Tubeless-Ready clincher carries the pedigree of the world’s most successful racing tire, proven from high mountain passes to the finales of the classics.
