*With a few setup tips and the proper chain.
The new Shimano™ 12 speed XTR™, XT™, and SLX™ groups are excellent kit, and you probably want to run one. We invested a lot of hours in setting up and riding these parts so we can recommend the best setup to maximize performance with our e*thirteen 12 speed cassettes. For everything we know on the subject, jump over to our comprehensive guides.
- Chain length is king. It is critical to follow Shimano's chain length instructions for proper performance. (These instructions are also contained in our comprehensive guides!)
- Chain selection is important. Shimano's new 12s chains (CN-9100, etc) were designed to work specifically with Shimano's new 12s cassettes.. and may cause problems with other cassettes. Choose a chain according to the attached design graphic for best performance with your e*thirteen cassette. (These instructions are also contained in our comprehensive guides!)
- Setup may be a little different than you're used to. Shimano™ 12s spacing is a little different than SRAM™. Our cassettes were largely designed around SRAM™ spacing, since that's all that existed when we started! This means you need to focus your attention on the largest steel sprocket on your e*thirteen cassette. Set up your shifting and limit screws as normal, then check for rubbing in the largest steel sprocket, and fine-tune to eliminate that noise.
- B-Limit tuning. The setup markings on the Shimano™ 12s derailleurs are designed for their 51T large sprockets, and thus don't translate directly to the large sprockets on our 9-46T and 9-50T cassettes. The short answer is you probably need to adjust the b-limit screw out a bit to get the best shifting performance. (Did we mention our comprehensive guides? they've got instructions to dial this in.)
