Specially designed to work with the tight tolerances and narrow profile of 10/11 speed chains and most high quality derailleur chains. The CT-4.2 is a powerful, precise tool designed to quickly and accurately remove and install chain pins. Without a doubt the most accurate chain tool Park has ever built!
Note: The CT-4.2 is NOT compatible with Wipperman chains.

Comments about Park Tool CT-4.2 Master Mech Chain Tool:
This is a must have tool for anyone that does their own repairs and maintenance on their bikes. I have owned several chain tools and this one is by far the best. It's not cheap but it will literally last a lifetime. It's makes removing and installing chains a breeze.
