the wheel set up is upgraded a bit, the rims are double wrapped in velox heat resistant rim tape, the tubes are thick walled - or thorn resistant - tubes, and the tires hold up to 110/120 psi. i air up my tires to around 15 psi less than their max to allow for air expansion due to heat from rim braking at those speeds. that bike has caged ball bearings in the hubs, my race bike used Crupi sealed machine bearings. i also do some mods to the front fork and - use dropout savers on front and rear. it may take a while longer to get my own bike back together, but ill post it when i get it done. fast eddie outty
