Compatibility

Shimano ULTEGRA HYPERGLIDE+ CASSETTE 12s (CS-R8101-12) is a Shimano cassette. It is a 12-speed component. Everything listed below was matched on a specification we hold for both parts: the interface each pairing actually depends on, such as freehub body, speed count, actuation or mounting standard. Where we could not verify that interface, the part is left out rather than assumed to fit.

Frequently Asked Questions

What fits Shimano ULTEGRA HYPERGLIDE+ CASSETTE 12s (CS-R8101-12)?

On this page we list wheels with a compatible freehub, rear derailleurs for this cassette, chains for this cassette. Each listing was matched on a specification we hold for both parts; anything we could not verify is omitted rather than assumed to fit.

Can I use a higher or lower speed chain with Shimano ULTEGRA HYPERGLIDE+ CASSETTE 12s (CS-R8101-12)?

No. Shimano ULTEGRA HYPERGLIDE+ CASSETTE 12s (CS-R8101-12) is a 12-speed component and needs a 12-speed chain. Chains for different speed counts have different external widths and inner-plate profiles, which causes poor shifting or interference with the neighbouring sprockets.

Which wheels does Shimano ULTEGRA HYPERGLIDE+ CASSETTE 12s (CS-R8101-12) fit?

Shimano ULTEGRA HYPERGLIDE+ CASSETTE 12s (CS-R8101-12) needs a rear wheel or rear hub with a HG freehub body. It cannot be fitted to a front wheel, and it will not fit a rear hub built for a different freehub standard without changing the freehub body.
