TRP Spyre flat mount caliper


The Spyre, 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. We 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. Rotors  are sold separately.


Adapters for 160mm rotors are supplied along with bolts. 


  • Weight: 154g per caliper
  • Dual sided actuation
  • Works with ALL cable actuated road levers. Compressionless (linear strand) housing is highly recommended
  • Comes with TRP ultra-grippy semi-metallic pads
  • Calipers are compatible with Shimano M525/M515 pads
  • 160mm rotors recommended on front wheel
  • Rotors, adapters, and flat mount mounting bolts sold separately
  • All flat mount calipers being mounted to the fork require the FF-5 Front Flat Mount 140/160mm adapter
  • For help identifying mounting type see our guide here.

Caliper options

Please note: Flat mount calipers will require the below bracket to mount them to the frame or fork. The only exception is when running a 140mm rotor on the rear as the caliper will mount directly to the frame.

Front calipers have short bolts. Rear calipers have long bolts.

Adapters and rotors are available in separate listings. This listing is for a caliper only. 

Compressionless brake cable set is highly recommended.
