I did IMLP last week. rode on a disc and zipp 303 in the front. Since I can’t get air into my tires ( I know, go on) I ask tech to help me. I have Continental Competition Tubulars on the wheels. Air pump dude says only go to 135 PSI–I say, go to 165 PSI (why I can’t do it on my own…) Ended up at 135. Any thoughts? Oh yeah, they were 19mm.
You should have thanked him.
Why??
For volunteering to pump up your tires, and for pumping them to a pressure that will give you a safe, fast, smooth ride. Tons of recent threads on lower rolling resistance at very high pressures.
So, not to sound incredibly stupid–I know that you prob. think i am–but in AZ Im put them up to 165—
What exactly happens?
P,S. I’m smart in other things–this just alludes me.

No, not at all, sorry. I was just being a smart ass.
There was a thread on here not long ago. joshatzipp had some rolling resistance data that said at really high pressures you start to get some tread seperation that leads to greater resistance. I’m still not totally sure I buy it, but josh knows his stuff and I trust him.
thanx–I’ll search it.
didn’t think you were being a smart ass, just thought you were thinking…oh god, one of these(**&&^%%$$ again…)
Acording to discovery team mechanic, they run 10 bars in the rear and 9.5 up front for the TT bikes. That’s around 130 to 150, but I don’t know their tires. This info was from comments on Cycling.TV with the head mechanic. I run 100 as I’m too lazy to keep on going, never had a flat in competition either. Could go a little faster, so maybe I should not take my own advice.
165 is too high, assuming you are a woman and not 200 pounds
I run 140 psi in my Conti Comp GP’s, 22mm front/rear
135 is probably right for you
