Fast tire. Despite the low tread, very decent grip. Slightly lower durability, 7 punctures after two months, but no problems, the milk works. So you don't have to worry, I ride about 6 days a week. I definitely recommend it and will buy it again. Of course, I ride it in the back

Bought for a girlfriend for a bike. I was surprised how such a not very active cyclist knew the difference. She originally drove a maxxis icon and when she switched to these tyres, she appreciated the stability, controllability and overall feeling more confident while driving. Maximum satisfaction.

Perfect fast tire. Definitely more for dry conditions but I could trust it even on wet grass, albeit at lower pressure, but cornering and braking were fine.

Super fast XC tire, very good grip in the dry, not ridden in the wet, so I don't know. ?
