The rapid pace at which drivetrains evolve these days might give you a headache when it's time to work on your whip. However, Pedro's Tutto Multi Chain Tool offers you a hassel free solution, as it's designated to service almost any chain on the market, from single speed to Campy's new 11 speed. The Tutto features Fit Dial technology, a rotating anvil that has four indexed settings with a corresponding usage guide conveniently laser etched on the handle for quick reference which easily adapts to almost any modern chain. The Tutto also features the Retracting Pin Guide, a spring loaded support that encloses the guide pin to prevent loss, bending or breakage, and guarantees flawless installation. And Pedro includes an 11 speed Peening Bit in the base of the handle for Campagnolo 11 speed chain installation, and the Guide Pin Sheer Slot allows you to cleanly remove guide pins. Lastly, the Tutto is built to last with durable heat treated steel, and can be easily disassembled for cleaning or of you need to replace a part.
