TRP Spyre mechanical disc brake with dual-piston cable actuation and 140mm rotor for touring bikes

Disc Brakes

Disc brakes deliver consistent stopping power in all conditions via hydraulic or mechanical systems, using calipers to clamp sintered/metallic or organic/resin pads onto 140-203mm rotors—with modulation and heat dissipation critical for performance on road, MTB, and gravel bikes.

Compatibility: "Check frame/fork max rotor size—exceeding it risks overheating and failure. 160mm rotors require 20mm adapter spacers on 140mm mounts."
