This award - winning, all - in - one bike tool is a must - have for cyclists. With 31 functions, it neatly folds into a lightweight two - piece body. It comes with a self - tightening tool and a nylon bag. The chain tool works with single - and multi - speed chains, including 10 - speed hollow pin (not for 11 - speed). Just press a button to separate the 31 - tool system. Made of an engineering grade plastic frame and hardened steel tools, it measures 3.4 x 1.7 x 1.6' and weighs 290g.
Using this Alien II folding bike multi - tool is easy. When you need to use a specific tool, just press the button to separate the 31 - tool system and pick the one you need. The chain tool can be used on single - and multi - speed chains, but remember it's not compatible with 11 - speed chains. After use, fold it back into the two - piece body and put it in the nylon carrying case for easy storage and transport. To maintain it, keep it dry to prevent the steel tools from rusting. If it gets dirty, you can wipe it with a clean cloth.
