BMX Brake Rotors

BMX brake rotors are the braking surface used by disc-brake setups, and the right one needs to match the hub, caliper position and the frame or fork it’s being fitted to. Blue Groove’s current range covers 120, 140 and 160 mm options, plus complete rotor-kit hardware where supplied.

Check rotor diameter and hub mounting standard first, then confirm the caliper and adapter are set up for that size. Moving to a different rotor diameter can change caliper position and clearance requirements, so it’s worth matching the whole brake setup rather than treating the rotor as an isolated swap.
