Great tool that does it all...

Versatile, Rugged
Best Uses:
Long Unsupported Rides, Bring it With You
This is a must have for long unsupported races and rides. It has everything you need to do almost every repair short of pulling crank arms. It's a bit bulky but given the versatility it's worth the weight and the space in your bag.
