Over 2 months, and been riding nearly every day. I think its a great tire, it's light at 850 grams which is loads lighter than any other "good" trials tire. The grip is very good, I would say Maxxis Slow Reezay compound is the only thing that can beat it for grip, but only just. The wear rate is the amazing! The tire uses a Black Chilli Compound that Conti do and they do bang on about it being super grippy but long lasting and to be fair they are right! The sidewalls are fairly thin so they are little more prone to punctures and at low pressures on off camber stuff it can be un stable and a bit un-predictable, but its a trade off. I saved well over 200grams on the rear of my bike and you will definitely feel that. I run the tire at slightly higher pressure than normal to keep it stable. Another plus side of the thin walls is that they make it very springy which is good
