Found a small adjustable crescent wrench this morning.

It's short. It's light weight. And it's perfect as I just put pedal extenders on my ride that prevent me from being able to remove the pedals with an Allen wrench. This is perfect since the pedals and the extenders need a different sized open end wrench. Now I can easily repair a pedal problem with a single wrench....without having to go to Home Depot and spending $8.
