I picked up one of these tires from one last week and after putting about 40 miles on it this weekend I thought I would give my impressions.
Casing measurement- 56mm
Knob to Knob measurement- 61mm
Rim mounted on- Edge AM 30mm wide
Weight- 1000+ grams
Pressure ridden at- 25psi
I mounted the tire up tubeless which was very easy to do. I actually mounted it once without sealant to see if it would leak and it held air all night. I remounted it the next day with a scoop of Stan's sealant in it.
This tire is very heavy! I put it on the scale and saw over 1000 grams and din't even bother recording the weight at that point. To me if a tire over 1k grams it isn't going to matter if it is 1050 or 1250, it is still really heavy. The Conti MK 2.4 with a tube that I took off weighs less then this tire tubeless.
The good- On the trail this tire rolls very, very, very fast! The solid center rib makes it roll like slick tire. It corners very good, you can lean it way over and rail around corners or just easy turns with no leaning. Fast flowing singletrack was great with this tire because you can corner so fast. It handled the small amount of mud we have right now better then the Mk2.4 that it replaced. It is suppose to rain all week so i will get to test it better in mud later this week.
The bad- The weight of this tire really becomes apparent when you get onto a trail that requires a lot of speed changes. If you have to do a lot of accelerations you will feel it with the weight of this tire.
I started out at 27psi and it felt good, at 24 it started to feel squirmy under braking and at 20 it was very unstable. I finally settled on 25psi as being the best handling without the squirmy feeling under braking.
The bike I did the test on is 4in travel Lenz Leviathan if that matters. I weigh 190lbs and 200 to 210lbs once all geared up depending on how much stuff I take with me. I am in the southeast and ride in Tennessee and North Georgia which is clay based hard packed dirt, rocks and roots.
