The Switch Tool has evolved. This new, compact and super-functional tool kit includes all the essentials you'll find on the Switch including T25 and T30 Torx bits, 2.5, 3, 4, 5, and 6mm Allen bits and a flathead screwdriver. The Big Switch also features an 8mm hex tool and a chain breaker. The chain breaker handle includes size 0, 1 and 2 spoke wrenches, a disc pad spreader and a Presta valve core tool. Individual T or L handle tools let you access tight places and give you more leverage on bolts and screws. Go ahead, fix everything.
