One-piece CNC machining process
When making the brakes, we use a whole piece of aluminum alloy for CNC machining to ensure the overall aesthetics of the parts while also maximizing the feel and braking rigidity, giving the brake handle a lighter feel and the caliper a large braking force, resulting in an ultra-competitive braking experience.

Oil bladder refill method:
The latest oil refill technology has been upgraded to oil bladder structure, the advantages are lighter and smoother feel, faster oil refill, stable brake stroke, and easier oil change operation.

Caliper part:
① CNC one piece caliper ② Heat dissipating brake pad ③ Brake pad bolt ④ Piston cover ⑤ Oil pipe screw ⑥ Oil injection screw ⑦ Original heat dissipating brake pad compatible with 7020, 8020

Compatibility:
XR brakes are not only compatible with flat handlebar road bikes, but also with flush mount mountain bikes introduced in the current market. Separate calipers are used by the majority of cycling enthusiasts as one of the spare options for road caliper modifications
