Pressures for Sewups
There are many threads discussing tire pressure, mostly suggesting that lower pressure is better, but I think these are mainly referencing clincher or tubeless.
What about tubular tires? Conti Sprinters are rated to 170psi, but surely riders are not pumping them that high? I thought one of the sewup's biggest advantage was lower pressures and pinch flat avoidance.
I use my 25c clinchers at 85psi/90psi f/r. Haven't been on sewups for years but can't imagine using those high pressures on the sidewalls.
