Rated 4 out of 5 by from Effective basic tool First off, tool is well constructed, it really feels like it'll last a lifetime, and it's so small that I think it belongs in every cyclist's road bag along with a spare chain. But the downsides are: can be difficult to operate, due to small size, especially in dark/rainy conditions. I got pretty desperate at one point and applied enough pressure to break off the drive arm component of the device, leaving me totally screwed with a [$]dollar key chain. I reccomend this with reservation that this tool is good, but not idiot proof. signed, idiot. PS: got off the mountain 8 hours later.

Rated 1 out of 5 by from Very Disappointing I bought this tool and the corkscrew pin snapped during first use. I know a thing or two about working on bikes and this tool just simply isn't made for the real task at hand. Not okay for a tool that costs $17.

Rated 4 out of 5 by from every toolbox needs this Simply put, if you enjoy biking and don't like taking your bike to the shop for everything, get this tool.

Rated 4 out of 5 by from essential You have to have one of these. The Park is well made and easy to use. Learn how to split, join and spread the chain on your doorstep, to reduce anxiety in the outdoors.

Rated 5 out of 5 by from As advertised Small, easy to use. Great for the shop but would work great if you find the need to carry one on the bike.

Rated 2 out of 5 by from Very difficult to use. I broke my bike chain not far from my house and decided to use this tool to put on a spare chain I had. After two hours of trying to line the pin up I still could not get it to go into the chain link. I don't know if I was just doing something wrong but even after reading the directions supplied with the tool I could not fix the chain. I ended up taking it to a bike shop and getting it fixed for less than the cost of the tool.

Rated 5 out of 5 by from A must have for all bicyclists Had an incident where some fellow riders broke a chain on their tandem bike. None of us in the group had a chain splitter. I decided this would be a necessary addition to my bike gear. I havent had to use it yet, but you never know when the need will arise.

Rated 4 out of 5 by from A decent chain tool for the price If you want to change the chain on your bike when it wears out you need a chain tool. If you don't want to pay to much this is the one to get. I only give it four stars instead of five because the handle is some what small and hard to grip while turning.

Does "any chain" include 11 speed?

Asked by: Kate Montana
Yes, the Compact Chain Tool. The pins on an 11-speed chain are the same size as an 8, 9 or 10 speed chain.

I have a 2010 fugi road bike .What tool do i need to remove it ? I still want to reuse this same chain .

Asked by: Julio62
This tool will allow you to remove your chain. For chain of that age, we recommend a replacement. If you have any questions about which chain would work, please contact your local REI.
