Sram Xg-1295 Eagle Cassette 10-50T 12-speed

Take a quick look at the SRAM Eagle XG-1295 cassette. The last dangling shred of an argument in favor of a mountain bike front derailleur is now officially dead. Designed for use with SRAM's proven, reliable XD driver body, this 12-speed, 10- to 50-tooth cassette offers an optimal 500-percent gear range at a considerably lighter weight than 2x systems. It carries with it the X-DOME architecture, which yields the strongest cassettes on the market. New shifting characteristics improve both, inboard and outboard shifting, as well as chain retention.
