I have been running these on my CX bike for the past year. They have proven to be great in almost all conditions! I run them tubeless on WTB STi wheels with Stan's sealant, which was easy to setup with an air compressor to seat. I usually run 40-45 psi and they grip great. They do wear fast if you put any miles on hard surface roads, but at the price point BTD has they are pretty cost effective. I just changed my rear after 750 miles but I have to travel a fair amount of hard surface roads to get to where I ride off-road. This review is of the 700x33 size tires. Give them a try, you won't be sorry!
