Pack-sized power.

Wee but effective, Park Tool's CT-5 Mini Chain Brute Chain Tool is perfect to throw in your pack for trailside repairs. The steel construction is burly enough to pop the pins out of any chain, and the large lever makes the Chain Brute easy to operate without taking your gloves off.

You need a trail chainbreaker

  • Familiarity: I've used it several times

What good is a spare link on the trail if you cant pull off the broken one? grab this mini chainbreaker. It's small enough to pack around but burley enough to get enough torque to pop out and chain pins. definitely the way to go.

handy gadget

  • Familiarity: I've used it once or twice and have initial impressions

great item to throw in your bag! Works great, ultra light, and small. Nice to have just in case!

  • Familiarity: I've put it through the wringer

This is a nice little tool to keep in your bag for those just in case scenarios . Chains break and sometimes you are a long ways from the car. This works great to get it back together and get you home.

Also works just as well at the work bench putting the new one on. This is the only one I've ever owned so I'm sure there is something out there that cost more that makes it easier but this gets the job done so there has been no need to look.

Not bad

  • Familiarity: I've put it through the wringer

Not a bad chain tool, but if you have a multi-tool with a chain tool, it'll do just fine. I prefer the Ct-3 which has replaceable pins for shop use , but this works fine and is half the cost. Don't expect life everlasting though.

Great, inexpensive option

  • Familiarity: I've put it through the wringer

This is a great alternative to the pro level chain tool, its light enough to fit in your pack if you don't have a multi-tool with a chain breaker, but also handles home shop duties with ease.

A most tool under the saddle.

  • Familiarity: I've used it once or twice and have initial impressions

You don't know when you're going to need one of these. Before this one I had a cheaper one and I beat the hell out of that. Now I decided to buy a new one and spend the money on a better quality tool. The quality is superb, it is a Park, what you expect. This is a most tool for any cyclist, believe me.

Throw one in your saddle bag

There are only a few specialized tools you need for bike repairs. This is one of them. Get one for each of your saddle bags and you'll have the reassurance of always being prepared.

must have

Get one. keep it in the pack or with all your other tools. quit borrowing your buddies....or needing to go to a shop.

Get it!

Tired of the junky chain tools that bend after using them twice, making it impossible to use? Buy this one and put those troubles behind you. Nice burly pin that wont bend and plenty compact to travel with you.

Solid chain tool

This is pretty much the only chain tool I've ever really used. I have a chain tool integrated on the multi-tool I carry for mountain biking, but aside from the incident that caused me to buy that multi-tool I have thankfully not had to break a chain in the field. I use this chain tool at home in the workshop and it works just fine for me. It breaks chains just fine, I ride 1x9 so I have to shorten every chain I use and after years of service on several chains a year this thing still works as if it were brand new.

Tiny Tool

Luckily I haven't had to use this yet. When I received it it felt a little heavy for it's size, but that's probably because it's made out of metal. It's small and sits out of the way in my pack. I'm sure I'll forget it is even there over time until my chain finally falls apart, which hopefully won't happen for a while. (Cross your fingers)

Small and Solid

While I haven't had to use this tool yet, it seems much more durable than your average mini chain repair tool. It seems many mini chain tools break the first time you use them, but this one seems bomber. While not ultra light and compact, it is still small and light enough that I plan to keep it in my pack all the time so I'm not stuck walking.
