The SunRace MX80 is an 11 speed cassette that is designed to be the perfect solution for riders that don’t want to resort to an expensive expander sprocket – and want a smooth, clean shift between gears.
With the massive 50 tooth sprocket on the back of your ride, you can mash up really steep climbs with fairly little effort and leave your friends in the dust.
11-50T wide-range MTB cassette upgrade for HG splined (Shimano/SRAM 8-10sp) freehubs. Not compatible with SRAM XD Driver.
7075 aluminum 42T and 50T cogs, all other cogs are steel.
7 cogs on 2 aluminum spiders, plus aluminum lockring and spacers.
Derailleur Compatibility: SRAM / Shimano mid or long cage derailleur (may require a longer B-tension screw or derailleur adapter for additional length)
