It SHOULD be ok. Are you sure its the crank and not the BB bearings? Its much more rare to ruin ISIS tapers than square tapers.
Cool. Don't forget the "wave washer" that goes between the non drive side crankarm & bottom bracket. Without it you will have lateral play. I rode mine for a month like that before realizing it was missing.rroadie said:Thanks, I just got a very sweet deal on a st of K-force light cranks with ceramic external BB from a guy who went power tap.
