The ULTIMATE Evo Titanium is not only light, but tough. Made from 3Al/2.5V Titanium the EVO excels both on trails and on the road, absorbing all unwanted vibrations whilst still providing the stiffness you need for optimum power transfer to the pedals. Designed as a 'do everything' clamping system, the EVO uses 2 bolts for unbeatable flexibility and precision in setup.
