A bike, a part, a question. Find the references and sources to take the next step.
Nobody walks into a bike shop asking for an 11-speed HG-splined 11–34T cassette. They point at the bit making a noise. This shop works the same way: pick a bike, pick the region, read what fits — with the two spec sheets we read to say so.
Every bike page lists its regions; every region page lists the parts that belong there with a verdict — fits, fits with an adapter, does not fit, or unknown. A bike we have not finished verifying says so at the top of its page, and only universal parts are sold for it.
