Stay on your bike and avoid feelings of embarrassment with the SRAM XG-1295 X01 Eagle 12-Speed Cassette. The cassette lets you tackle moderate slopes with the typical 10-42t configuration and then click over to the massive 50t cog when the pitches start to get the better of you. Although principally designed to help keep your legs turning during power-sapping switchbacks you also will be able to scorch flatter trails in the 10t cog making it ideal for lighting up smooth hardpack.
