Frame
Our new B'Twin Ultra frame is derived from Evo Vario technology. 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
This frame is UCI-approved.
Total weight: 1400 g in size M.
Fork / suspension
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 damping effect on very uneven and bumpy terrain such as cobblestones. Aerodynamic design with brake located as close to the fork as possible.
Total weight: 550 g in size L.
