Park Tool - CT-3.3 - Chain Tool

Park CT-3.3 Chain Tool 

From Park: 

• Comfortable T-handle
• Replaceable driving pin 
• Investment cast steel body
• Adjustable locating shelf

A professional quality shop chain tool that works on 5-speed to 12-speed road and mountain bike derailleur chains*, including SRAM® AXS® 12-speed and Shimano® XTR® 12-speed, as well as 1/8", 3/16", and half link chains. The CT-3.3 features an adjustable locating shelf so it works on any width chain to remove and install chain rivets. Built to last and easy to use, the CT-3.3 features a comfortable handle, investment cast steel body and replaceable driving pin.

Notes:

• The CT-3.3 will install, but not peen, Campagnolo® 11 and 12-speed chain rivets 
• The shelf fastener sizing is preset to allow easy adjustment from one width chain to another. Any attempt to lock the shelf in place will result in damage to the tool.

From Porkchop: This is my favorite chain breaker. It is unbelievably heavy duty and the pin is replaceable. It is actually designed primarily for derailleur chains (3/32") but will work with 1/8" chains (which is what I use it for) although Park recommends the CT-7 for 1/8" and super wide 3/16" chains. So why do I choose the CT-3 over the CT-7? Because I only deal with 3/32" and 1/8" chains (and you probably do too) and would prefer to have a single tool that works on both. While quite a bit more expensive than the Rivoli Cyclo chain tool that we also sell, the choice comes down to investing a little more in a tool that will last a lifetime.
