These lovely quality Shimano XT Italian thread bottom brackets are increasingly hard to find. Deore XT was Shimano’s top flight MTB group from 1987 and for many years was used with the classic M730 cranks. This version is the particularly tricky to find version for Italian threaded frames with a 70 mm BB shell. The loose bearing, sealed cone design means they are well guarded from muck ingress and offer easy maintenance.
