Overview
What Makes the CT-3.3 the Right Chain Tool?
The Park Tool CT-3.3 is a professional chain tool designed to push pins cleanly through bicycle chain links for breaking and rejoining chains across a wide range of speeds and chain types. Its hardened steel pin aligns precisely with the chain's drive pin, driving it through the outer plate without bending or distorting the link plates. The CT-3.3 works with 5 through 12-speed chains, covering virtually every modern drivetrain standard in a single compact tool.
A quality chain tool is one of the most-used items in any bike mechanic's kit. The CT-3.3 gives you the precision and durability to handle chain work correctly every time, whether you're shortening a new chain, repairing a snapped one on the road, or swapping between drivetrains during a build.
