DER CPY FD19-SR12B S RECORD 12s BZ-ON

Constructed of forged aluminium and unidirectional carbon fibre with titanium stop screws

The external monolith body in carbon fiber has been shaped to enhance the efficiency of the chain movement when going uphill and the readiness and fluidity in descent

Micro-adjustments to the front derailleur position, which can be activated by the controls, help to prevent any contact with the chain, even in the case of maximum crossover

Designed to improve maximum chain crossover and prevent contact and friction with the drivetrain

Designed for compatibility with tires up to 32mm
