Ko-Bikes Bottom Bracket
Features a super thick and stealth axel with M12 bolts
Fits both 73MM and 68MM BB shells, simply by using the supplied spacer.
Features an aluminium body shell and BB cups, to save the unnecessary weight.
Ideal for "Front freewheel" systems, with the 127.5MM axel length.
Runs on 3 highest quality cartridge bearings from Japan
(2 on the drive side of the BB, and 1 on the non drive side of the BB).With these bearings, this BB will out last most of the existing BB's on the market, and still be super smooth after a lot of use.
Weight: 12.5oz / 354g
