TRP HY/RD Post Mount Disc Brake Caliper

The TRP HY-RD brake caliper provides the power and modulation of hydraulic disc brakes and is compatible with any cable actuated Shimano and Sram road shift brake lever system, sold as singles - one required for each lever.


Please note: Post mount fitting and rotor sold separately (not included)





  • Hydraulic reservoir provides automatic pad wear adjustment
  • Self-contained caliper incorporates master cylinder
  • Cable actuation means compatibility with all mechanical road and CX brake levers
  • Includes TRP's own ultra-grippy semi-metallic pad
  • Compound works well in dry conditions
  • Composite pistons isolate heat better than steel
  • Manufacturer recommends use with 160mm rotor
Got these installed last night and did my first ride. Nice feel overall. Takes a little fiddling to get the lever throw just right on my 5800 shifters, but overall I'm happy. Much better feel than the Spyre it replaced (rear only).
