The Park Tool CT-5 Mini Chain Brute Chain Tool, while smaller, punches above its weight by being as reliable as a shop tool. The compact size, special V handle, and replaceable pin, make chain removal and installation easy, even when you are on the go.

Note: Video incorrectly says that chain breaker only goes up to 11 speeds. The video is from before 12 speed existed.


  • Works on 5 to 12-speed bicycle chains including SRAM and Shimano 12 speed
  • Shelf for loosening tight links
  • Perfect take-along chain tool
  • Will install, but not peen, Campagnolo 11 and 12 speed rivets
  • Not compatible with all single speed chains (works with 3/32" and 1/8". Will not work with 3/16")

Dimensions: 60 x 55 x 15mm (2.4 x 2.2 0.6")
Weight: 77g

Great tool! Strong enough to handle the shadow conspiracy interlock half link. I'm sure it works even better on a normal chain.
