This review is for the redesigned PRO version of this tire.
This is an amazing all-round tire with very even transition of knobs throughout the tire. It actually can hook up quite decent up front as the knobs go pretty far to the outside of the tire. Mounted on 28mm internal rim these 45mm blew up to 46.5mm WAM.
Ran this at unbound XL with zero flats and have continued to punish them on all kinds of terrain with no issues so far. Very satisfied with road feel and capabilities on chunky stuff. I really don't see why you would run the RS version now that these are so dang fast and likely better tread protection.
I purchased these to be my backup racing and everyday training wheels. My racing wheels are narrow tubular rims which don't allow for a quick change should I have a blowout either training or racing. Having a set of quality clinchers gives me a back up and, in the event they experience a flat, the possibility for changing the tube/tire quickly. These are a nice set of true, smooth rolling wheels of high quality that should last a long time.
I've been riding the 35mm AS TR for the last two years, with approximately 10,000 miles on two pairs, 90% on road and 10% on gravel. Not one flat that I had to repair. These tires are fast, comfortable, grippy, and durable. The tradeoffs for those qualities are some weight (mostly due to the 35mm size) and cost, neither of which is significant in relation to the benefits. I used to think that flatting once a month was part of the experience of riding a bike, or I could stretch that two months if I rode tires that felt like bricks (28mm Conti 4-Season or Schwalbe Marathon). Riding these tubeless tires is the most significant improvement in cycling equipment I've experienced in the last three decades. I'll go back to downtube friction shifters before I give up these tires. I used some other fast gravel/all-road tires before these, and while they were ok (Schalbe G-one variations and others) they were not as fast and wore out faster. I will switch to some knobbier and fatter tires if I'm going to be mostly off-road, but otherwise this is peak cycling tire for my needs.
A good fast training and (B/C) racing tire. Rolling resistance and grip feels comparable to GP 5000's, (running 28mm with TPU tubes at around 4.5 bar). I ride 8-10k a year and they are decent on imperfect midwest roads (urban to rural). Puncture resistance is decent with glass, but less so with wire and metal objects. They come with wear indicators, so easy to determine when a replacement is due. Very easy to mount and dismount on carbon, hooked rims.
