S&M 22mm Euro Bottom Bracket
S&M 22mm European Bottom Bracket. Aluminum threaded cups, 2 sealed bearings per side, 15/16" to 22mm sprocket adaptor, tube spacer, bearing cone and washers. Everything you need. I had to run my Solid Bitch cranks on my Euro Killing Machine so I got this and ended up switching back to Profiles to use the Solid Cranks on another bike. Threads are nice, bearings are smooth, ready to roll.
