The Good: fast rolling tire, light weight, works in various conditions, good value
The Bad: None so far
I've had the opportunity to run these tires in a couple of various conditions and so far they have done great. These tires have a low rolling resistance and at the same time are fairly light weight making for a very fast rolling tire. I've used them a bit in the skatepark, and they have worked great but also tried in in several conditions on the dirt jumps and pump track.
The tires grip really well on dry hard-pack tracks and also held up well when the pump trackwas a bit greasy after rain, I had no issues leaning the tires into corner and berms, they felt comfortable and kept their line. In the dirt jumps they were flawless, I even cased a jump pretty hard and the tires had no issue, my rim on the otherhand wasn'ttoo happy.
Overall if you are looking for tries for your dirt jump,pump track or urban assault (do people still ride urban?) bike I would strongly recommend these.
