The brake wire pulling method is changed to the inside, which not only solves the problem of wire cornering, but also improves the feel and braking power

Through many improvements and tests, our BR-05 has fully realized the bilateral braking effect

Why choose a dual piston brake?
General brake single piston work leads to easy rotor deformation, uneven left and right friction, and limited brake braking power
BR-05 Dual piston work
Rotor always keeps central position, not easy to deform, smooth friction between left and right side, high braking force
