Interesting. All my weekend riding companions are riding Continental Gatorskins with butyl tubes pumped up to like 110 psi front and rear.
I’m really delighted about these high thread count Challenge open tubulars on the A23 rims, for my next ride I’ll try bringing the front pressure down closer to the 72 front you mention.
