Shimano’s 10-speed sprockets primarily feature the “HYPERGLIDE Technology”1 models, but there are also models utilizing “LINKGLIDE Technology”2 for e-bikes and the new “CUES” components.
While both HYPERGLIDE and LINKGLIDE are Shimano’s shifting technologies, they are not compatible with each other. Therefore, it is important to ensure that the shifting technology matches when selecting a Shimano 10-speed sprocket.
Below are the models, shifting technologies, and features of Shimano’s 10-speed sprockets:
Model | Shifting Technology | Features |
---|---|---|
CS-HG500-10 | HYPERGLIDE | Wide ratio sprocket for old and new 10-speed drivetrains |
CS-HG81-10 | HYPERGLIDE | MTB, SLX grade wide ratio sprocket |
CS-HG50-10 | HYPERGLIDE | Sprocket for both road and MTB; 11-36T only |
CS-M771-10 | HYPERGLIDE | MTB, SAINT grade wide ratio sprocket |
CS-M980 | HYPERGLIDE | XTR grade MTB sprocket with titanium in some low gears |
CS-7900 | HYPERGLIDE | DURA-ACE road grade cross-ratio sprocket |
CS-6700 | HYPERGLIDE | ULTEGRA sprocket, available in cross and wide ratios |
CS-5700 | HYPERGLIDE | 105 sprocket, available in cross and wide ratios |
CS-4600 | HYPERGLIDE | TIAGRA sprocket, available in cross and wide ratios |
CS-LG600-10 | LINKGLIDE | Deore 10s LINKGLIDE sprocket, 11-43T only |
CS-LG400-10 | LINKGLIDE | CUES 10s sprocket, wide ratio options |
CS-LG300-10 | LINKGLIDE | CUES 10s economy sprocket |
In the past, Shimano’s road HYPERGLIDE 10-speed sprockets were typically cross-ratio for road bikes and wide-ratio for MTB. However, current models are mostly wide-ratio configurations.
Model | Shifting Technology | 11-23T | 11-25T | 11-27T | 11-28T | 11-32T | 11-34T | 11-36T | 12-25T | 12-27T | 12-28T | 12-30T | 12-34T |

Since higher-end models like the DURA-ACE are discontinued, current options for purchase are the “CS-HG500-10” or “CS-HG50-10”. If you can find used models, you will have a broader range of gear combinations from cross to wide ratios, making it easy to customize gear ratios simply by swapping the sprocket, which is a major benefit for road 10-speed setups.
Additionally, while some of the older 10-speed rear derailleurs may not be compatible with current road 10-speed sprockets, the new 10-speed road and gravel models are compatible with both old and new sprockets.
