Free yourself from the chains of not being able to work on your own chain. If you think that's a mouthful, how about this: I need to work on my chain but don't have a chain tool so have to go to the bike shop where they'll keep my bike for 2 days and charge me 40 bucks to replace my chain. So now you know the power of the Park Tool Master Chain Tool. This chain tool is designed with precision so it's ready to master even the smallest pins on 11-speed road chains, plus, its new Integrated Link Pocket design keeps the chain perfectly straight for ease of use.
Integrated Link Pocket ensures precise alignment
Replaceable rotating pin so you don't have to replace entire tool
Perfectly contoured cushioned handles for ergonomic use
Precisely machined investment cast body and components for durability
Includes removable anvil to peen Campagnolo 11-speed chains
Note: The CT-4.3 is NOT compatible with Wipperman chains.
