Park Tool CT 3.2

Stuck it on the chain over a peg. Twisted a few times and the metal piece on the tool popped off. Initially I thought maybe it was some peg pusher adapter that wasn't secured.

This broken, correct? It didn't take much at all. It looks broken to me. The metal is cracked.

You just put this peg pusher end over a peg hole in the chain and twist to push out a peg in the chain, right?

Nothing wrong with it -- just a little blurry is all.

The metal peg? That snapped off. That's not broken?

This is what it's supposed to look like.

Nothing about the peg being replaceable....

. . . or operator error.

I have 40+ year old Cyclo Chain tools that are still fine, I, too, suspect the problem is the User of the tool.



You see that star shaped thing at the base of the pin, that you broke, that is where you Unscrew it and screw in the replacement Pin.

good luck try to be more careful next time..

That's what I'm thinking too. I barely even used it, but I was cranking the crankset shortly before that. Took it out of the package, swilled it a few times... snap!

I couldn't find anything that looked like the original pin segment. I also couldn't find the segment that I hammered back in place last fall.

Looks like the chain waits a week or two while parts come in....

We have a the older CT-3 chain tools here at the co-op. I've run across some replacement pins as being bad; snapping on first use. Not lately though. Newbies do bent the pins somewhat frequently, when they don't seat the chain fully in the tool.

Yep, me. I see I was more like half on the pin. And three hard cranks and it was done.

My first disappointment with Park Tools (not that others would do any better). I thought this tool was indestructable.
I've got spare pins ordered. The pins must be pretty delicate. I wouldn't mind if the tool was able to crush the chain links themselves, but that's not how it is apparently.


I'll have to see if there's anything else around me business-wise that might have a chain tool....

Wow, the pin is half the price of a chain tool.

I still have a Cyclo and, other than the pin falling out if I am not careful, it works great. I have a Park mini too.

I have never broken a pin. It could only happen if it was not centered on the chain pin.


I don't know what you mean here. Why would you want to crush the chain links?

Sounds like user error to me. Check with Park, they are pretty good about honoring their warranty.

Maybe you need to drop by a professional Bike Shop for Lessons on how to use your tool Properly?

I have the CT5 which seems to be working perfectly.

I had a Chinese tool that the pin disintegrated on first use.

Based on his other postings he needs to drop by a professional bike shop for a lot more than just this problem.

There's a reason that the better chain tools have the ability to replace their drive pins and the OP just found out why. One technique I use is when the tool is positioned on the chain and the initial twist of the handle (or the first bit of the tool's pin driving on the chain's pin) I will back off the tool pin a half turn or so then re tighten it. I have felt the two pins become better aligned this why. And it's usually the pins not lining up properly that caused the tool pin to bend/break. Andy.

Part of it was going from tightening the crankarm on and then shifting to the chain.

And part was thinking the Park Tool was invincible and would just crush the chain (or squeeze the pin out like toothpaste) if it was lined up. It crushes itself.

Cassette's on. Left and right arms/chain ring is on. Old chain is still on, but the bike still functions. I just have to wait. And I need to figure out how to adjust the front derailleur since it won't shift far enough to the right to get the biggest sprocket. (I'm assuming a greased taper pin with the correct toque on the crankarm screw would push the crankarm as far as it's going to go.)

What is a greased taper pin? What is a crankarm screw?

Inventing your own terms for bike parts doesn't help in clear communication with others.

The CT 3.2 costs like $36.

A pkg of replacement pins (2) is about $4.

Where did you get that the pins cost 1/2 as much as the chain tool?

Those pins break if you don't seat the chain perfectly. The other side of the chain pin will get caught on the opposite side of the tool, so you're pushing against the tool itself instead of pushing the pin out. It happens. We've all done it once.

Buy a new pin and be more careful next time. It's not the tool's fault.
