Shimano SQUARE TYPE BOTTOM BRACKET (BB-UN101-K) Compatibility Guide
Quick Verdict
Shimano SQUARE TYPE BOTTOM BRACKET (BB-UN101-K) is a Shimano bottom bracket. Everything listed below was matched on a specification we hold for both parts: the interface each pairing actually depends on, such as freehub body, speed count, actuation or mounting standard. Where we could not verify that interface, the part is left out rather than assumed to fit.
How this list is built: a part is listed only when we hold the specification that decides the pairing for bothparts and those specifications match: the freehub body for a cassette and a wheel, the mounting interface for a chainring and a crankset, and so on. Each card shows exactly what was compared. Where we do not hold that specification the part is left out rather than assumed to fit, so this list is deliberately incomplete rather than speculative. Always confirm against the manufacturer’s own compatibility documentation before buying.
