Shimano Deore CS-M6100 12-Speed Micro-Spline Cassette / 10-51t


With the Deore cassette CS-M6100, Shimano introduces the 12th sprocket for the inexpensive Deore beginner groupset. As with the top component series, the Hyperglide+ shifting aid construction ensures particularly smooth and quiet gear changes, even under load. The largest sprocket has 51 teeth, the smallest only 10, so this cassette is only compatible with Shimano Micro-Spline freehubs.
