As for tarmac, I tend to agree you shouldn't pump it up to max.....but......what % of your route will you really benefit form the lower pressure?
My last TT bike ride outdoors was 30ish mi. I pumped up to a pretty solid 80/75 psi on 23/25 combo. I think there was a total of a minute to two minutes total accrued "rough road" that entire ride. The rest was smooth other than minute changes in texture.
It takes a pretty solid screwup in pressure choice to suffer 50w of damage for an entire ride.
Yeah, agreed on the 50 watt scenario. I base my pressures more off comfort and no loss of speed, i.e. balance. Being that I am on the lighter end of the spectrum for total system weight and I don't run 22s anymore that ends up being 55/55psi front and rear, respectively, on my road bike. I'm running 23/25 schwalbe pro ones (old version) that measure out to 25 and 28 on my 19mm internal Easton wheels. They are setup tubeless. I likely ride some of the nicest pavement in the nation outside of the random broken stuff. But when I do hit that broken stuff it's not a question of am I losing 5 watts or not but how that impact impacts my ride.
Time Trial bike is a whole other animal and I will keep those trade secrets to myself. š
