FAQ

Which Park Tool chain tools does the CTP-C pin fit?

The Park Tool CTP-C fits the CT-1, CT-2, CT-3, CT-3.2, CT-3.3, CT-5, and CT-7 chain tools. The card itself names a shorter set, but Park Tool's own compatibility list is the broader one above.

How many pins come in a Park Tool CTP-C?

Two. The Park Tool CTP-C is sold as a card of two replacement chain tool pins, so you still have a spare after the first repair.

What tool do I need to replace a Park Tool chain tool pin?

A 7 mm or 9/32 inch box end wrench, or a 12 point socket in the same size. Park Tool publishes a step by step guide to chain tool pin replacement if you have not done one before.

Why do chain tool pins break?

The pin carries the entire load of pushing a rivet out of the chain, which is why it is the part that bends or snaps first. Most of the broken ones we see at the lab came from the tool not sitting square to the link, so keeping a spare pin is normal rather than a sign the tool is bad.

Best For

Best for anyone who owns a Park Tool chain tool and would rather spend a minute replacing a pin than buy a whole new tool. It is also the right thing to keep in a shop drawer or a race day toolbox, because a chain tool with a bent pin is worse than no chain tool at all. You find out at the worst possible moment.
