I determine myself not to go to the trail during the rainy season as the trail is getting more and more dangerous otherwise I do a routine XC riding during the summer. Nevertheless I’ve ever ridden with these tyres just to tested their capability against the mire. These tyres could easily removed them after passed a sludgy part of the trail but they tend to be slipped off when you do a speed cornering. Meanwhile these tyres are only for dry conditions. On the other hand riding on road could easily been passed with them.
For most of you who consider yourself as a weekend warrior, do some occasional XC riding, and tend not to be serious in mountain biking thus these tyres are for you.
