Thanks, I also like that pic..
I do not race those if very muddy.. they don't hook up as well as knobby's in the mud. but on stones, logs and roots they are the bomb I always take a look at the track before a race, and decide then, if I'm running knobby's or trials..
You can also make the trials work well in mud, but I still think knobby's are the best choice if it's really muddy..
hmm well considering im in Ireland 99.999% of what i ride is muddy haha thinks i'll stick with the knobby's! although i might get one just to try cant do now harm hehe
