The chain tool is fundamental to bicycle mechanics. As drivetrains push the envelope, however, chain tools must evolve to keep pace. The Pedro's Tutto Chain Tool II has done just that. The Tutto II blends ergonomic, organic design and noticeable industrial stature with patented innovations like the Fit Dial and RPG and novel additions like the Peening Bit for Campagnolo 11, 12, and 13-speed chain assembly, ergonomic set-back handle design, and Guide Pin Shear Slot. These unique features and a new replaceable bridge make the Tutto II the most versatile chain tool available, compatible with almost any chain from single speed to 13-speed and beyond including SRAM Flattop chains. Lastly, the Tutto II was designed with season after season of professional service in mind featuring heat-treated tool steel construction for superior strength and lasting performance, and simple disassembly to make servicing and part replacement easy. Backed by Pedro's lifetime warranty.
