Buying Guide

Mechanical vs hydraulic

Hydraulic systems typically offer stronger, more consistent stopping power while mechanical sets are easier to install and adjust without bleeding

Rotor size and compatibility

Confirm rotors (commonly 160mm) match your frame/fork mount and caliper clearance for safe installation

Piston count matters

4-piston calipers deliver higher braking force and modulation for heavier riders or e-bikes, while 2-piston calipers are lighter and simpler

Hose length and fittings

Check supplied hose lengths and fittings (front/rear) to avoid extra parts or trimming for your bike's routing

Included hardware and rotors

Kits that include front/rear calipers, rotors, mounting bolts, and adapters minimize additional purchases and installation time

Material and lever feel

Aluminum levers and solid rotor construction improve durability and lever feedback compared with cheaper stamped components
