Polytetrafluoroethylene coated, and stuffed for great Puch performance. Super high quality crank with roller bearings top and bottom.This crank takes all the normal E50 bearings and seals.
*We had this crank made for us, and is not to be confused with the DMP Teflon crank that had an unstuffing problem. So far we have no reports of this crank failing. It is super high quality Teflon stuffing that will stay in place.
