Park chain tools only work on specific chain speeds ?

(I posted this question in a related thread, but got no responses, so thought I'd try again).


This concerns the little CT-5, I'm not sure about the larger unit. I'm seeing some ads saying they work with 5-10 speeds, others saying they work with up to 11 speeds, and others saying they work with up to 12 speeds. They all just have "CT-5" on them, no "CT-5A", or "CT-5 gen 2", or anything like that.
So what's the deal, are there different variations, or are they all the same, and all compatible with up to 12 speed chains, and maybe I'm just running across older ads with older specs, that maybe pre-date 11/12 speeds?
I ask because i just ordered one, (got a deal from a very reputable ebay vendor in the UK), that says it works up to 10-speeds (I only have 9 and 10 speed bikes), and that it's Made In the USA (I've read the latest ones are made in China. Is that accurate?)

The current Park web site description of the CT-5 claims it works on 5 to 12-speed chains. The only disclaimer is that it won't peen Campy chain pins but most other chain tools won't either. I believe you are seeing older, pre-11 and 12-speed descriptions. If Park had to modify the CT-5 for 11 and 12-speed chains they would have changed the model number and they haven't.

I have one I bought in the 9 speed era and recently used it on a couple of 11 speed chains. I didn't notice it working any differently.

Read the directions for the chain you are using. For 10, 11, and 12 speed chain some/all (?) manufacturers don't want users to push the pins out of the chain and then push them back in. This removes the micro-peen on the end of the pin and it could fail under load if a user does this.

You can get re-useable quick links that make it easy to reomve/re-install the chain. Buy the quick-link pliers for removing the link.

For example:

Almost all chain manufacturer's from 8-speed on up recommend against reusing a standard pin and provide either specific joining pins (8,9,10-speed Shimano) or a reusable master/quick link (SRAM, Campy, KMC, Wipermann and some 11-speed Shimano). The chain tool is used to remove a pin completely while sizing the chain and then to push in a special joining pin if your chain uses one.

+1 on the quick-link pliers. Most quick links are pretty hard to remove without one.

This was already instantly true when chains when to 7/8 speed and started peening rivets.

Not new information or technology.

Really only use a chain tool to size now. Almost never to reconnect.

I've used an older CT-5 that I picked up at a garage sale on chains up to 11s. It works great.

There are some peened 11s chains that are TOUGH!!! But, so far my CT-5 is up for the task. Perhaps I should buy some extra pins for the tool just in case.

It was news to me when I read this on BF.

I got back into bike mechanics a couple years ago when I built up a new/vintage bike from the frame up. I set it up 2 x 10 and used my trusty 1980's chain tool to size the chain AND push the pin in to get the 10 speed chain back together. I road this bike for quite awhile before I discovered that this was a no-no.

No problems fortunately.
