I've broken my rear hub so I'm after a new one – anyone seen any good deals on a 6-bolt, 32 hole one? Hope would be ideal but will consider anything that has cartridge bearings (eg not Shimano)

are you keen to keep existing spokes? If so go for soemthing with the same flange size as your existing hub.

Ideally, yes, keep the spokes but that will be fine for the majority of roughly Hope/Shimano dimensioned hubs.

Superstar – tempting but not keen after Neil's antics on here. Plus IIRC quite a few people had problems with them didn't they?
