This is a 12-speed MTB cassette for riders who want a broad spread of gears without losing useful steps through the middle of the range. The 10-51T combination delivers a 510% range, giving you a fast 10T top gear and a generous 51T climbing gear for steep, technical or loaded rides.
The carefully spaced progression moves through 10-12-14-16-18-21-24-28-33-39-45-51T. In real-world riding, the lower gears are particularly well spaced for steep terrain, making it easier to adjust your effort as a climb changes rather than jumping straight into a bailout gear.
HYPERGLIDE+ shift ramps support fast, smooth changes while you continue pedalling. The BEAM SPIDER construction is designed to reduce cassette inertia and improve chain security, and the 470 g average weight keeps this wide-range option suitably manageable. Fitment is via a MICRO SPLINE freehub body, with an HG 12-speed chain specified for compatibility.
A strong choice for trail, enduro, bikepacking and steep-terrain riders who want a wide 12-speed range with closely usable climbing gears.
Wide 10-51T range
The 510% spread gives you both a useful 10T high gear and a 51T low gear for steep climbs.
12-speed progression
The 10-12-14-16-18-21-24-28-33-39-45-51T sequence provides practical steps across varied mountain-bike terrain.
HYPERGLIDE+ shifting
Precisely shaped ramps help make gear changes fast and smooth, including while you continue pedalling.
BEAM SPIDER construction
The lighter, stiffer spider design helps reduce cassette inertia for quicker acceleration and supports chain security.
MICRO SPLINE fitment
The freehub standard enables the compact 10T smallest sprocket, but your wheel must have a compatible MICRO SPLINE body.
470 g average weight
A sensible weight for a wide-range 12-speed MTB cassette, helping keep the drivetrain responsive.
HG 12-speed chain compatible
Designed for use with an HG 12-speed chain as part of a compatible 12-speed drivetrain.

Generic is a catalogue designation for products presented without a distinct store-brand identity. The term describes the retail classification rather than a separate manufacturer history or geographic origin. Generic-labelled products can still have clearly defined specifications, standards and compatibility requirements. For this component, the catalogue designation is retained while the fitment details identify the relevant road bottom bracket application.
