Sunrace Wide Range 12 Speed Cassette 11-51t
The SunRace CSMZ903 WA1R 11-51t 12 Speed Cassette provides a massive gear range for Shimano® 1 x 12 drivetrains and is optimized to follow the gearing steps of the new Shimano SLX/XT/XTR 12 speed groupsets.
The cogs are spaced and profiled to work with Shimano’s new 12 speed groupsets and chains but without needing a Microspline® cassette body – it fits right on the standard Shimano® type cassette body.
Built with light weight alloy cog carriers, hard wearing chromoly 11-39t cassette cogs and AL7075-T6 alloy 39t, 45t and 51t cogs to keep the weight down and drivetrain stiffness up.
Each jump through the gears is designed to keep your leg speed stable and efficient, maximizing every watt of energy.
Designed for the new 12 speed Shimano® groupsets SLX (M7100), XT (M8100) and XTR (M9100)
12 Speed 11-51t
7 cogs on 2 aluminium spiders
