Revolver Posted June 17, 2009 Report Share Posted June 17, 2009 i have square trialtech forgedUseful!Square taper seems to me to be easier to round, but look after it and its no different to an ISIS one.I think there is more choice of ISIS BBs and so there are better ones, but ISIS cranks are often more expensive (like the middleburns)For a mod, 160 or 165.
