It is poorly worded. I run 95 psi. There is no adequate answer since it’s not 100 and also no less than 90…
even better, I run 110 front and 90 back due to different wheel types(old school and fat arse)

Subtract 10 from each if it’s wet

Isn’t the bigger unaccounted-for variable the rim width for the PSI you are running???
130lb
Tubular
120psi front and back.
My bike mechanic put that much, it feels fast so I keep it that way.

I ran 110 psi last weekend and will run 80 psi this coming weekend using the same tires. Very different road surfaces.
Josh’s biggest point in regards to getting people to change their mindset in regards to pressure though is that people interpret road vibrations as fast. They’re not. Smooth is fast. We have this idea of what fast should feel like but frankly its 100% wrong. I’m not sure exactly about the effect running tubular have but I promise you that pressure is not fast unless you only ride on a velodrome.
Agreed. I have different wheel sets with different internal widths and difference size tires. I run any thing from 85 to 125. And 5psi less if I’m near race weight.

Yes, that too. As well as tube or tubeless…

Whoo! I hope you’re runnin 20s!

^^^^^^This
Too many unaccounted for variables.
Josh’s biggest point in regards to getting people to change their mindset in regards to pressure though is that people interpret road vibrations as fast. They’re not. Smooth is fast. Reminded of when in the early 90s a friend and I started riding fire roads on our road bikes (like gravel riding today!!). The first day we went down this super hectic descent - it seemed we were slamming it fast, bouncing all over the place.
12mph.

Aren’t those different sets for different purposes though? I also have a bunch of different wheels of different widths with different tires and different pressures. My winter training wheels are running 28s at ~75psi. But the poll question was specific to tri/TT racing, which 95% of the time for me means 23s at ~100psi.

Yikes. Latex vs butyl discussion aside, do you realize how much speed you’re losing here? You could easily be running probably ~90 depending on your weight and have a more comfortable ride, and way less rolling resistance.
The roads aren’t THAT different

the poll is an exact repeat if a poll we ran here in january of 2017. had i gotten any feedback then i’d have changed the text. but if i want to show a comparative study i have to keep the text the same.
here’s a preview, which i don’t think will surprise you: 32 months ago 19 percent of you said you were running pressures of 120psi and higher. now it’s 9 percent of you (as of this post). today, 37 percent of you say you’re running pressures of 90psi or lower. back then it was 18 percent.
i think josh and tom a. and some of the other guys posting here have made an impact on you all.
