Loving this multi-tool from Lezyne, it has everything you will need out on the road all weighing in at around 100g. It contains a Phillips screwdriver, T25 wrench, 2/3/4/5/6/8/mm Allen wrenches, a chain breaker, a Mavic splined spoke wrench, and two square-size spoke wrenches. The tool is beautifully finished and just feels like something you are going to have for life. Made by the same people that are behind the Truvativ brand, pretty much all the products I saw on their stand at Interbike bring the same style and quality. You can pick one up at Performance Bikes for $29.99.
