I would like to build some vintage pista rims for my brother's '67 masi special. He is a muscular guy - weighing in at 220lbs or so - and I'm wondering if the rims of that era are to 'soft' or should I go with more stiff 70's - 80's rims (ie. hard anodized and double eyelets)? These rims and bike would be for track use only. Suggestions welcomed !
