SRAM's top-of-the-line X.0 is a serious rider's and racer's dream. Expertly crafted with a full carbon cage, and a titanium main spring, the X.0 is light enough to grace the winningest bikes out there. It's renowned for its precise, consistent function, efficient 1:1 actuation ratio and SRAM's Direct Route cable technology, all of which ensure that every single shift is crisp and lightning-fast. Plus, with sealed bearings, this sweet changer is built to last, too.

An important part of a rear derailleur's job is keeping the chain taut as you change gears. Chain-wrap capacity is a number that tells whether or not a derailleur will be able to do this on the drivetrain you plan to use it on. Calculate chain-wrap capacity with this formula: Chain-wrap capacity = (large chainring - small chainring) + (large rear cog - small rear cog). Example: 46/34/24 chainrings and a 12-34 cassette: (46 - 24 = 22) + (34 - 12 = 22) = 44-tooth chain-wrap capacity.
