The Big Switch Ratchet Multi Tool from Blackburnisscaled down from a full-size ratchet, but that doesnt mean it skimps on performance. Ittakes the same simple necessities from the popular Switch and Big Switch and adds a convenient, ratcheting handle for even quicker, hassle-free adjustments. Extra-long 2.5 through 8mm allen bits take care of business, along with T25 and T30 Torx, the renowned Wayside chainbreaker, 0, 1, and 2 spoke wrenches, a disc-pad spreader, flathead, and a presta valve core tool. Youre covered. Fully covered.
