Light and resistant levers in a premium finish

The Delta RS levers are made from Carbontaz Premium, a material developed by Bontaz from composites and carbon fibre. This material has the advantage of being twice as light as aluminium for the same tensile and breaking strength. Bontaz brake levers are also removable and interchangeable.

Powerful and precision brake

The forged 4-piston calliper and the optimisation of the lever travel, make the Delta RS one of the most powerful and easy-to-modulate brakes on the market. The adjustment of the guard is facilitated by a dial that allows a quick manual manipulation.
