I've found slicks last much longer than knobblies on tarmac, to the tune of thousands of miles. I off road on slicks quite often and find my full length mudguards usually start packing up in conditions where slicks have problems. As long as the slicks are a reasonable width they can be quite capable in a variety of off road conditions.[/QUOTE]
With the the Maxxis Xenith you use,...is it the 26 x 1.50 inches size?
