Shimano Dura-Ace Di2 Components

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.

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.

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.

The CeramicSpeed SLT headset bearings and coated T47 bottom bracket nearly eliminate friction with a self-lubricating, corrosion-resistant, maintenance-free design. Hand-built in Denmark, garunteed for life.
