SHOP CHAIN TOOL SINGLE-SPEED AND 5-12 SPEED PARK TOOL CT-3.3

The Park Tool CT-3.3 is the shop-quality chain tool for removing and installing chain rivets, the operation behind every chain sizing and replacement. It is compatible with virtually all single-speed and multi-speed chains, from 5 up to 12 speeds.

The body is investment-cast steel, strong and precise, paired with a comfortable handle that lets you control the force on the pin. The floating locating shelf adapts to any chain width, so the driving pin always works centered on the rivet. The driving pin is replaceable: when it wears, fit the Park Tool CTP replacement and the tool is as good as new.

CT-3.3 chain tool compatibility

• 1/8", 3/16" and half-link single-speed chains
• 5- to 12-speed derailleur chains
• SRAM T-Type and SRAM Flattop
• Shimano XTR 12-speed
• Campagnolo 11-, 12- and 13-speed chains: installs and removes rivets, but cannot peen them

A chain tool is needed every time a chain has to be sized, replaced or opened: from the new bike to be prepared to the worn chain to be changed during a service. Having a tool with a floating shelf and a rigid body on the bench means working with the pin always in line and reducing the risk of crooked rivets, on modern drivetrains as well as on the single-speed chains of urban and fixed-gear bikes.

How to get the best from it

• Before use, check that the driving pin is tight in the handle
• Seat the chain on the floating shelf, not above or below it
• Keep the pin straight and centered on the rivet while driving it
• Periodically grease the handle threads
