Our new B'TWIN ULTRA frame is derived from the Evo Vario concept. Aluminium is an ideal choice for obtaining an excellent propulsion-to-comfort ratio. The variable thickness tubes considerably reduce the weight and ensure excellent performance on all surfaces, even very rough terrain. The design is aerodynamic, the cabling is integrated into the frame and the rear brake is positioned under the chainstays. This frame is UCI-approved. Total weight: 1400 g in M.
Our new B'TWIN ULTRA Evo Vario fork is mounted exclusively on the B'TWIN ULTRA Evo Vario frame. The combination of carbon and aluminium offers perfect synergy between the B'TWIN ULTRA Evo Vario frame and fork. We have achieved a filtering effect on very uneven terrain such as cobblestones. Aerodynamic design with brake located as close as possible to the fork. Total weight: 550 g in L .
Shimano 105 Direct Mount brakes (fork and chainstay): their double pivot technology provides precision and power, the centring is still perfect with the DPB technology, and they are made from cast aluminium and covered with powder paint that withstands frequent washing.
