5-10 PSI makes a WORLD of difference

Jeez, Weisan, you're complaining about serious pains in your thighs and you don't mention that you're running lower tire pressures? Let's get all the relevant information out on the table, ok? Now we know why you're hurting. And that Costco Coke? You should know that Dr. Pepper is the only approved remedy for Texas summer riding.

I am crackin' up here...love you bro!

hmmm, checking tire pressure with my fingers is totally inaccurate.

on 23 mm tires, I really can't differentiate between 70 psi and 100 psi...they feel the same.

I also never experience the 'gee, wish my ride was more comfortable' thing...at 147 lbs, I kinda enjoy bombing along on 90f /100r.

Sera pal, it takes years and years of practice and hard work before one can get to that level...since we are such pal, I will let you in on my secret training...buy a couple of boxes of Tofu from HEB, go home and practice applying finger pressure on them just enough to create an imprint without actually breaking them up into pieces...do that for 10 years, come back and we can talk again.

>>at 147 lbs...

At that weight, tire pressures becomes moot. Add Fried chicken and Costco into your training program....PRONTO!

I'll pump up my tires about 1x/week (or two sometimes) and as long as they're not close to pinching when I roll it out of the garage, I'll ride it.

I know guys that are religious about pumping up tires to X psi EVERY ride. I never have gotten that, but different strokes for different folks.

I've got a pair of 30c tubulars on my Crosshairs. They get pumped up hard. ...and I mean HARD! at 60ish psi. They're normally only at 50-55psi

Started this morning with the thumb test and thought mmmm maybe alright but added air. 50 rear, 45 front set out and inside of 5 miles pulled over and said to myself, self trust the thumb it's worked for alot of years psssst things got right. That's what I get for trying to over think these things.

Much smoother comfortable ride. That, great weather, and some new (to me) rock n roll chain lube made today a great riding day!



Think I'm going to stick with it for a while.

You should reverse the psi in your tires or drop the front more. The rear tire takes most of the load and as such you need less air in the front to match the feel of the rear.

Ha! You caught a typo.. I rub 95 rear and 90 front.

I ride vintage steel bikes. Aside from a couple tubular-equipped wheels which happened to come with something narrow, everything I have is 25mm or wider. I generally don't get above 80psi in the rear, even less on the wider stuff. I keep my mouth shut (but mentally roll my eyes) when I hear people in the ride group talk about pumping their tires to 115-125psi.

The tricky part is that everybody has become accustomed to the harder feel of higher pressure, with its vibration and firm impacts, as being what it feels like to be 'fast' on your bike.

Turns out that the only thing 'fast' about those pressures (and that feel) is how long it takes for your carpal tunnel syndrome to act up.

yeah on a recent group ride we were going over a rougher section of road and a club mate said "man! with an aluminum frame and tires pumped up to 120, this is a killer!" and I'm like "dude, you weigh 140ish, you need to drop at least 20 psi!" and he acted like I was speaking Chinese. oh well...

That's a crappy way to ride through life. Ignorance is bliss, I guess.
