I run 27 front, 28 rear on Enve 4.5AR wheels. mounting was a breeze and they inflated super easy. I follow Enve's recommended PSI in general but go a couple PSI above recommended (59 front/60 rear). The 27's inflated and settled in at 29.5mm which is just at the 105% rule on the Enve 4.5Ar's. Riding in CO on mountainous chip N seal and these tires are supremely supple, smooth and handle wonderfully. They are very fast too. I run a Power meter and can verify they are faster on real roads and climbs than what a steel drum indicates. :). Even at higher PSI's for my 167lbs on 25mm internals, they run more supple and smooth than Schwalble Pro One TLE Addix's by far! I do wonder by some of the reviews if an earlier production tires had issues ? The rubber is a little softer which adds to the road feel and cornering stability but Im not concerned about getting the longest lasting tire, I am happy with the best rolling and handling tires. I ride about 2K miles a season and these are my favorite tires I've ever run.
I bought the tan walls in 29s and instantly loved em. About the same as any tubeless tire to install. I mounted the on my mavic cosmic rims, filled em with Muc-off sealant and rode em since September till last week (2.1.21)when I finally got a deep cut on the rear tire. Overall they had about 2K miles on em and did awesome. They feel smooth, handle well in wet, cold, hot, and stick in hard fast corners. Only drawback is that after about 2 months the tan wall started to brown. And by the time I switched em they looked as brown and ugly as old boot leather. Granted yes I know they will change in color but it seemed as if they browned a lot faster and more than other tan walls. Other than that they're great and worth the money. A good switch from the GP5000s I had been running
I can't compare these to others but they do squeal loudly under hard braking when new. They provide enough braking, so I learned to rear-bias braking force and minimize the noise. The rear didn't seem to squeal as much anyway. As they wore to the limits, they braked better with less noise. They're on Dura-Ace 9000 brakes which have no adjustment for toe-in. You might get some conical bushings and try toe-in, but then they might wear faster to the limit line at the inward point. I recommend letting them bed in using the brake alignment as-is (near parallel).
