Buying Guide

Match rotor diameter to your caliper

Choose the rotor size (e.g., 200mm, 220mm) that aligns with your brake caliper and frame/fork clearance to preserve pad alignment and braking leverage

Confirm mounting standard

Select a 6-bolt or center-lock rotor to match your hub interface; using the wrong mount requires an adapter and can affect performance

Consider rotor construction

Two-piece and vented designs manage heat better on long descents, while single-piece rotors are lighter and simpler to service

Prioritize heat management for e-bikes or heavy riders

Rotors labeled e-bike-ready or with reinforced designs resist warping under sustained braking common with heavier loads or powered riding

Check compatibility with pads and calipers

Ensure your pads and calipers are compatible with rotor material and thickness to avoid glazing, noise, or uneven wear
