The Big Switch Multi-Tool has evolved. This new, compact and super-functional tool kit from Blackburn includes all the essentials including: T25 and T30 Torx bits, 2.5, 3, 4, 5, 6 and 8mm 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 keys, 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. Compact enough to pack so you?ll never be left in the lurch.
