The Box One Square Taper Titanium Bottom Bracket Gold is the gold standard among bottom brackets. Features a square taper, hollow titanium-nitride-coated titanium spindle. Yes, that sounds like a lot, and it is, but it certainly doesnt weigh a lot. Between 185 and 190 grams. The titanium spindle makes this component super stiff to keep in line with Boxs philosophy of stiffening the whole drivetrain (and handlebars) in a bid to get the very most out of each and every pedal rotation. Other features include carbon fiber center seals, abec-5 bearings, and alloy cups.
