My rear hub failed The freehub mechanism on the Sunrace hub (Capreo-style for 9t cassettes) suddenly isn't freewheeling anymore, but is so draggy that the derailer arm bends, and the chain goes slack and derails. And this is after only 300 km. Looks like a warranty matter. I really hope the replacement is longer lasting. If not I'll be switching either to an SRAM style hub for their 10-42t cassettes, or to an Alfine 11 (not cheap).
