Interesting. That hasn't been my experience with the Grifo XS at all. I've ridden the same trails on both Jack Brown greens and Grifo XS. For me, the small knobs offer quite a bit of grip in sections that leave the JBs slipping and spinning out.
I haven't had any cornering issues on asphalt with the side knobs on the Grifos, nor has the tread peeled away. And I've used them quite a bit on pavement, riding many miles to-and-from the trailheads. I've found them to be quite durable and fast tires for any setting, and definitely preferable to similar width slicks on dirt. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
