Microspline packages

Microspline cassettes are designed for Shimano 12-speed mountain bike drivetrains and offer a wide gear range with a small 10-tooth starting cog. The Microspline freehub has more closely spaced splines, distributing the load more evenly and improving durability, especially with wide-range cassettes. Hyperglide+ technology ensures fast, smooth shifting, even under load. The range includes Microspline-compatible rear cassettes from the Shimano Deore, SLX, XT and XTR series, with several gearing options, such as 10–45T and 10–51T. These cassettes are particularly well suited to modern trail, enduro and XC riding, where precise shifting and a wide gear range are required across varied terrain. Microspline cassettes are compatible only with a Microspline hub.
