Question:  Coach Fred, regarding your July 2015 review of the Compass Barlow Pass tires: You mentioned the tires felt a bit squirmy at 50 psi. What rim width were you using? I have the narrower Stampede Pass on 19C rims and they feel fine at 65 psi. I'm considering the Barlow Pass on a new bike with 21C rims and I've been assured by Compass that combination will work well. – Stuart Fogg

Coach Fred Matheny Replies:  I was using a set of Mavic Open Pros. I'm not sure of their width, but they're traditional rims that are 10+ years old so are probably pretty narrow.

I'm guessing that Compass is correct and that the 21C/Barlow Pass tires combo will work fine. They have a lot of experience with different rims and their tires!

On a side note, I was on the 6-mile descent from Black Canyon NP this morning with a strong side wind riding my Compass Stampede Pass (32s) on Velocity A23 rims at about 60 psi. Again I felt the slight squirm on two fast corners.

I like pressures a bit higher than Compass now recommends although I'm not sure exactly why. I weigh only 150 so there isn't a lot of side pressure on the tires.

I suspect that each rider needs to fine-tune tire pressures to his or her comfort level. A bit of experimentation is good!
