The XX DH Transmission cassette is designed to deliver small steps for big power. With a full X-Sync tooth profile, the 7-Speed DH specific cassette is the best shifting, most robust DH cassette SRAM has ever made. And just like Eagle Transmission, shifting under load isn't just possible, it's better. This allows you to never let up when dropping gears, letting you get to the next split quicker than your competition. And when milliseconds matter, XX DH Transmission might just be the difference between qualifying and going home. Available in two variants, XD and XD SLIM to optimize for different hub dimensions.Utilizes well accepted and broadly available XD driver bodyIncludes Setup Cog for fool-proof set upFull X-Sync tooth profile for best-ever inboard and outboard shifting performance under loadOptimized 7-speed, 10-24t gear steps optimized specifically for DHT-Type chain compatibility only (Sold separately)Item SpecificationsCassette Body TypeSRAM XDCogs10-12-14-16-18-21-24ColorSilverDefined ColorSilverDrivetrain Speeds7Range10-24Weight150 SRAM XX Downhill T-Type XS-797 7-Speed Cassette Cassettes UPC: 710845928017
