Had issues with spare Roval wheel put it in to two shops told bearings were not in right so they sorted cost £50 . It seèmed ok till I put it back on bike then binded up . Not much info on this forum so sent it to Berkshire. Seems there is a 18mm spacer chamfered on one side and that was the problem. Not available as a spare part seemingly but they bodged one up for me free of charge.
