SRAM XX1 Eagle XG-1299 Cassette - 12 Speed
The only way to describe SRAM's XX1 Eagle groupset is as a wholesale revolution in mountain bike drivetrain components. The world's first production 12-speed groupset does more than just add an extra gear to the cog, but is effectively the final nail in the coffin of the MTB front derailleur. The centerpiece of the Eagle groupset is the utterly massive 10-50T cassette. By giving you a rear cog as large as a road bike chainring, Eagle gives you a massive 500% gear range that's considerably lighter than a traditional 2x system. The X-Dome architecture of the cassette makes it the strongest and stiffest cassette on the market, with improved chain retention and shifting characteristics. The XX1 Eagle cassette is only compatible with XD driver hubs and SRAM Eagle 12-speed derailleurs.
