I'm a noob slowly accumulating tools. I've replace my chain using a multitool, but now I think I'm ready for a proper chain tool. This seems like a simple matter, however... I have a bike with an internal hub gear and uses a 1/8" single speed chain, and I recently got a bike with a 10 speed chain. I'd like a tool that can handle both, but looking online, many chain tools specify that they're compatible with "derailleur chains," but not SS.

The Park Tool CT-3.2 does both, but it's pricey, and I don't know that I need a heavy duty shop grade tool that I'll use a couple of times a year. Are there other options?

Also, a tool that includes a shelf for loosening tight links might be useful (which the Park tool doesn't have). I've done this by hand after reinserting the pin, but it's a bear. Is this feature really useful?

This seems like a simple matter, but I've gotten myself confused. Does anyone have any suggestions? Thanks in advance.

The demands of a 1/8" SS chain are very low, so just about any chain tool is fine. This is especially true if you're using a connector so the tool is only used for cutting, not splicing.

The only issue for some chain tools is the length of the pin. Some that are made for narrow chains are a bit short for wider chains and will not push a pin clear through. There are two ways to mange the issue.

1- push as far as possible, then flex the chain sideways to spring the inner link clear of the remaining pin stub.
2- push both pins on the same outer plate in clear of the plate, so it's free to come off. Now slip the link with both pins attached free on the opposite side as you would a master link.

my Park Tool CT-5 (about 15-18 dollars) works well. i can remove links on 1/8" chains and replace them. remove and replace links on 3/32", 6,7, and 8 speed chains made for derailleur bikes and remove links on 9 speed chains with a bit more effort. i don't replace pins on 9 speed chains. i've been using it now for about 20 years.

I also have a Park Tool CT-5 "mini chain brute". I've used it to break and rejoin single-speed and 5/6/7 speed chains. I've used it to shorten modern 10-speed chains, although those get rejoined with a quick link. It's a good little tool.

I have the CT-5 and found it difficult to work in 10 speed chains. I ordered this based on good reviews.

How was it difficult to work on 10 speed chains? Was the Topeak better?

I discovered this, which is supposed to work on single speed and multi-speed:

Topeak® - Universal Chain Tool

Does anyone have experience with this tool?
