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.

Chain compatibility comes down to one standard most boxes print as a speed count: the chain width. Here it is for the two KMC chains people ask about most, and what it means on an 11-speed and on a 12-speed bike from the fleet.
