Hey now, Grant is alright and produces some great bikes...I've owned three of them over the years and still have two. What he doesn't make is a modern singletrack shredder because I think what Riv thinks is dirt riding is more about fire trail/wide rolling dirt path than singletrack.
But, from what I've seen, XC courses do seem to be on the smooth side....ideal for a hardtail.
Yo, RJM, I'm happy for you and Imma let you finish, but Petersen's retrogrouch opinion doesn't carry any weight on this discussion
