Bike Multitool, 11 Function Bicycle Tool,Red,Blue

It works great. I mainly bought it because it was better to carry around in my bag for riding instead of bringing a couple more tools with me. I used the 8mm hex wrench (which is an adapter BTW) to remove my crank arms and to install them. The chain breaker on it works, but when putting the pin back in, the part of the chain breaker that pushes the pin is too long, so I had to hammer the pin back in a bit then use the chain breaker to push it back into place.
