I tried riding on the road with my tires at 160 psi once. My commute was no faster then it had been with tires at 110 psi, and as an added benefit, my water bottle cage bolts had rattled loose by the time I got home.

Yeah, the tire pressure calculator I use has me inflating 700x23c front and 700x25c rear to just 88psi, based on a 135lb rider weight. Even if I weighed 200lbs, it would still be less than 110psi front and rear. Needless to say, the inflation pressures for larger section tires are much lower. The only time I run pressures over 100psi is on the track with tubular tires.

Honestly, 140psi on just about any street in America sounds like absolute hell.
Bro..... Come on bro.... Where did I say to run 140 psi on the streets of America? I said the tire has a higher max psi and even at equal PSI has a lower rolling resistance than Gatorskins. So on the hardwood, or on your crumby dilapidated streets the Rubino is faster. Obviously you adjust psi for weather and street conditions. I've never run 140 psi but I'd like the option if I were at the track because yes it's faster. You shouldn't even ride a tire with less than 120 psi at the track.

This is all wrong. You were actually going so fast that the space/time continuum shifted slightly, making it feel like you were going the same speed. Extreme G-forces caused your bolts to loosen. You also didn't age during that particular ride. It's science.

That depends on your frame and fork. How much clearance do you have between the tire and the frame or fork? If it's already pretty tight, you're not going to be able to fit a wider profile tire.

Why in the **** would anyone want to run gatorskins on a track anyway? If you were responding for track conditions than your first post was pointless.

Also, GP4000s or GTFO!

Late to the party, but fill in the blanks anyone.



Had a fun time a while back watching a cyclist and a motorcyclist argue this one.

Go back and read what I said. On the track or on the street a higher psi which results in lower rolling resistance is at least as fast if not faster than a lower psi higher rolling resistance tire. Don't be an old fogey riding a heavy ass bike and tires like Scrod.

I know what you said...you told the guy to not get gatorskins and to get Rubino Pro's instead because you pump them up to 140psi and really fly. This insinuates that he should pump them up to 140psi for street riding, and I called you on it. Then you said that's for the track and I called you on it again.

And don't you worry, I'm rocking GP4000s which are only 205g, which puts me in at almost a full ounce of medical grade goodness lighter than yours, per tire, bro!

Running 700x23 Gatorskins here and I have had no issues whatsoever with them. I run them at about 108 or so, between 105 and 110. They ride smooth enough for the streets here and so far the protection against the f word has been pretty good. Anyone that thinks that these tires are bad should try the Specialized Armadillos. Holy hell those suck.

I run a 28mm Clement Strada LGG on my FG these days. I also got rid of most of my Gatorskins - just hate their feel and grip in the wet.

The idea of high PSI <25mm tires being faster in street (aka imperfect) conditions has been debunked a lot. Even on 23s I don't go higher than 100 PSI.

don't you pay extra tax on that then, import?

Usually no. I usually buy my tires and tubes from Pro Bike Kit. Takes about a week or two for everything to come, but the shipping is usually free and no tax.

I also just bought a smart trainer from Ribble and that came in less than a week...no tax, no import, no shipping. (And it was $250 cheaper than anywhere I could find it in the states.)
