Method & sources

Every compatibility entry is built from public, authoritative sources:

• Manufacturer technical documentation (Shimano, SRAM, Campagnolo).
• Industry reference guides (Park Tool Repair Help, BikeGremlin, Sheldon Brown).
• Official product specs by model and generation.

Freshness

Standards change (new freehub bodies, new speeds, new chain types). Entries are reviewed when a new standard ships, so the tables stay current — it's the main reason we exist: blogs go stale, here they don't.

Limits

We don't replace a mechanic's advice or the manufacturer's specs. When in doubt about a specific model, check the official spec sheet or ask a workshop.
