I am using a set of Super Champion clincher rims on my P-15. They presently are laced to Phil Wood hubs, but I will eventually rebuild them with Campy hubs. On my chrome P-13, I am running later Weinmann clincher rims that have hook beads. I have the original Weinmann wheels for both, clinchers for the P-15 and tubulars for the P-13, but I prefer using more modern clinchers.
