Can I mix Shimano and SRAM at 12-speed?
No. At 12-speed the systems diverge: SRAM road uses a Flattop chain and cassette + XDR, while Shimano uses Hyperglide+ on an HG/Micro Spline body. Chains and cassettes are not interchangeable, and shifters/derailleurs have different cable pull. Stay within the same 12-speed ecosystem.
Standards involved
What you need — before you buy
- These parts aren't compatible as they are: you need a component built for the correct standard — see “Standards involved” above.
- Identify your exact hub/frame first (brand, model and year), then match the replacement to it.
- If your part doesn't support the other standard, use a component compatible with the standard you already have.
- Match the part to your exact hub/frame: check brand, model and year. Don't choose a freehub body or component by standard name alone.
