Just got my new Sugino CBBF-103 bottom bracket, and am trying to figure out the correct torque spec for it. Park Tool gives a range of 435-608 in-lbs for cartridge type bottom brackets, but doesn't have anything specific for a Sugino. There was no documentation included with the BB, and I can't find anything on their website either. Anyone know what torque I should tighten these down to?
