Thanks to its full X-SYNC design, the harder you pedal, the better it shifts. Designed for a 55mm chainline for less extreme chain angles throughout the full range and delivers more precision. It’s 520% range has been optimized with larger 38 and 44-teeth cogs prior to the 52-tooth cog for improved gear steps in the low end (compared to the Eagle drivetrain 10-52-tooth cassette). Featuring a clearly marked Setup Cog, install is both simple and foolproof. Plus, it utilizes a Pindome design for gears 1-8 and a single piece mini-cluster for gears 9-12.
