Aspire to perform.

The TRP Spyre is a mechanical disc brake that offers superior performance with incredibly easy setup. This is a dual piston actuated mechanical disc brake caliper which provides precise clamping force. This translates into even pad and rotor wear because the rotor does not need to flex to one side during braking. TRP added a simple cable barrel adjuster to make fine tuning easy. All of this in an incredibly thin 40mm, 146g package, that works with any drop bar levers on the market.

Compatible with flat mount frames and forks. Compressionless (linear strand) housing is recommended for best performance. Rotors sold separately.


  • Dual sided actuation.
  • Works with all cable actuated road levers.
  • Comes with TRP ultra-grippy semi-metallic pads.
  • Calipers are compatible with Shimano M525/M515 pads.
  • Weight: 154g per caliper.

I bought a pair. Flat mount for the rear. Very simple to setup. Lever force required is still pretty high, but the feel is exceptionally firm, even with full length housing that was required in my case. Note that the 1800mm housing supplied with a Shimano cable set is barely long enough if you ride a larger bike with long chainstays.
