I put a 100mm Phil Wood square taper bottom bracket into my Surly Pugsley 3yrs ago. Then I abused the bike a ton including saltwater, sand, winter slush and corrosive playa dust. Most BB’s would have just been thrown in the garbage after that sort of use.
The BB and spindle looks fabulous despite the condition the rest of the frame was in. The bearings were serviceable, but notchy enough I sprung for the $25 to put new bearings in the BB since I had everything out of the bike.
So if you need a durable BB and don’t want a throw away unit consider a Phil Wood.
BTW – I should give some love to these $35 Shimano Alivio cranks. They were cheap and work great.
