Shimano cassette sprocket compatibility: 7- to 12-speed match tables and how to pick
About the Author
Sesera editorial account organizes laptop, mini PC, smartphone, and gadget buying guides so readers can check the important points before buying.
Shimano cassette sprockets split by speed count and the spec on the wheel, even inside the same maker.
When you change to 11-speed, 12-speed, or a larger tooth count, speed count alone cannot set the matching part.
A product is a buy candidate when the rear speed count and the wheel spec match, and the tooth count is within the derailleur’s maximum.
This article organizes Shimano cassette sprockets you can pick from the speed count you have now and the use.
7-speed through 10-speed match
| Current condition | Recommended product | Matching spec | Tooth-count condition |
|---|---|---|---|
| 7-speed | Shimano CS-HG200 7S 12-32T | 7-speed HG | 12-32T |
| 8-speed, 11-32T | Shimano CS-HG31 8S 11-32T | 8-speed HG | 11-32T |
| 8-speed, 12-32T | Shimano CS-HG200 8S 12-32T | 8-speed HG | 12-32T |
| 9-speed, 11-32T | Shimano CS-HG400 9S 11-32T | 9-speed HG | 11-32T |
| 10-speed, 11-32T | Shimano CS-HG500 10S 11-32T | 10-speed HG | 11-32T |
Shimano CS-HG500 10S 11-32T
The 8-speed 45T exception
- On a CUES line with U2000 support, Shimano CS-HG400 8S 11-45T is a candidate
- A typical 8-speed rear derailleur is outside the 11-45T range
- On a usual 8-speed bike, 11-32T or 11-34T lines are the pick
CS-HG400 8S 11-45T is for 8-speed bikes that use a U2000-compatible derailleur.
A typical 8-speed rear derailleur is outside that range. 11-32T or 11-34T lines are the pick.
11-speed road match
| Current condition | Recommended product | Matching spec | Tooth count |
|---|---|---|---|
| Typical 11-speed road | Shimano CS-R7000 11S 11-32T | 11-speed road HG | 11-32T |
| Higher grade first | Shimano CS-R8000 11S 11-32T | 11-speed road HG | 11-32T |
| Older HG wheel | Shimano CS-HG700 11S 11-34T | Fits 8- through 10-speed HG | 11-34T |
| Older HG, higher part | Shimano CS-HG800 11S 11-34T | Fits 8- through 10-speed HG | 11-34T |
On an 11-speed road wheel at 11-32T, CS-R7000 is the pick. CS-R8000 is the higher part.
CS-HG700 and CS-HG800 are 11-speed 11-34T that can mount on 8- through 10-speed HG freehub bodies.
If you convert an older wheel to 11-speed, the derailleur and chain also need to be 11-speed parts.
MTB match
| Current condition | Recommended product | Matching spec | Max tooth count |
|---|---|---|---|
| 10-speed, up to 42T | Shimano CS-M4100 10S 11-42T | HG | 42T |
| 11-speed, up to 42T | Shimano CS-M5100 11S 11-42T | HG | 42T |
| 11-speed, 51T support | Shimano CS-M5100 11S 11-51T | HG | 51T |
| 11-speed, higher part | Shimano CS-M8000 11S 11-42T | HG | 42T |
| 12-speed MTB | Shimano CS-M6100 line | MICRO SPLINE | 12-speed part |
For 10-speed MTB at 42T, CS-M4100 is a buy candidate. For 11-speed, CS-M5100 is.
12-speed MTB uses the MICRO SPLINE spec, so a conventional HG wheel is outside the range.
CS-M5100 11-51T is for 11-speed MTB that has a rear derailleur that can take 51T.
12-speed road match
| Current condition | Recommended product | Matching spec | Tooth count |
|---|---|---|---|
| 105 line | Shimano CS-R7101 12S 11-34T | 12-speed road HG | 11-34T |
| ULTEGRA line | Shimano CS-R8101 12S 11-34T | 12-speed road HG | 11-34T |
| DURA-ACE line | Shimano CS-R9200 12S 11-34T | 12-speed road HG | 11-34T |
| Bike that takes 11-36T | Shimano CS-HG710 12S 11-36T | 12-speed road HG | 11-36T |
At 11-34T you can pick from 105-line CS-R7101 through DURA-ACE-line CS-R9200.
If you match the grade you use now, these three products are the main candidates.
CS-HG710 11-36T is for a bike that has a rear derailleur that can take 11-36T.
Q&A
Can you use an 8- through 10-speed cassette on an 11-speed road wheel?
On HG spline L, an 8- through 10-speed cassette matches with a 1.85mm spacer.
Can you use a 12-speed road cassette on an 11-speed road wheel?
A 12-speed road cassette also matches HG spline L. The derailleur and chain also need to be 12-speed parts.
