I'm a super clyde (6'5, 255) and have been using the Chinook Pass EL on my road bike--and pumping them up to 110 psi, to boot. No problem so far, after a few hundred miles, and they are the most comfortable tire I have ever ridden--much, much more comfortable than a set of 700 x 38 Vittoria Randonneur Hypers I had on another bike. I have just ordered the Barlow Pass tires (700 x 38) in the EL version for a new build.
