I’m a big fan of Compass tires.
I was first introduced to them 2 years ago when I was considering a bespoke all-road bike from Mariposa Bicycles. They recommended the Compass 700 x 35 tires for the bike. I have been riding with them for 2 years, and have been pleased with their performance and comfort compared to the 25mm and 28mm tires I had been used to.
After 2 years, and a lot of hard riding, I needed new tires. Mariposa suggested I try the 700×38 version of the tire, saying they are more comfortable, particularly on the torn up city streets. A few days ago I took delivery, and immediately put them on the bike.
I didn’t expect much of a difference. A little more comfort, and possibly slower because of the the lower pressure and greater weight.
Well, was I surprised.
They are certainly no slower. On the first ride I recorded several Strava PRs. They are substantially more comfortable. I inflated them to 50 psi in the back and 35 psi in the front. They weren’t cushy feeling but rolled over the bumps smoothly as if I had shock absorbers on the bike. The most notable difference, however, was on the descents. I felt more confident, tucked lower, and cornered at speed.
Now, I’m a bigger fan than ever, and enthusiastically advocate the use of wider tires on raid bikes.
