I had been riding 65psi front and 85psi rear but am thinking of going lower.
I tried 65psi and 70psi rear and liked the better cushion.
Not sure how much lower I should go
thoughts?
I'm 210 and I ride Vittoria Corsa Control 2.0 at 68/70 in a 28c tire and love the plush, fast ride. So I'd say you're still way too high.
Silca has a terrific inflation calculator that takes into account road, weight, tire size when mounted, and riding style in the advanced version. It's from data accumulated over all their time working with World Tour teams on inflation. Check that out. For those weights, the calculator says a lot closer to 71/72 psi front/rear.
