Bilateral drive is more stable, synchronous oil pressure force transmission, and integrated caliper improves rigidity; It provides a super-strong and uniform force, which can be braked at the touch of a button, and the even force is generated by the horizontal dialing force, so that the disc is not easy to defor The bearing turns to improve the handle of the brake handle, and the caliper has a good locking force, thus having a super competitive experience. Split design makes it easier to install the inner wiring, and increases the piston to provide more force. Both front and rear are compatible with 140/160mm discs. High-performance heat dissipation antenna, multi-metal copper-based ceramic formula, unique aluminum wing design, improving heat dissipation performance by 25% CNC integrated caliper processing, which is loved by the majority of cycling enthusiasts, is also an alternative for highway caliper modification.
