Abbey Bike Tools SL Dual Sided Crombie Tool

Abbey makes bike tools for serious mechanics and folks who really care about quality, and the SL Dual-Sided Crombie Tool puts your standard wrench-and-lockring combo to shame. The stainless-steel handle is thinner than the standard Crombie, saving 124g for the traveling mechanics without sacrificing leverage or durability, and the dual-sided design works with Shimano, SRAM, and Campagnolo cassettes, so one is all you'll need.
