I think it's the shifty ground, BikerHen. I really hate that about being on the dirt. If the trail is really flat, then it's not quite so bad, but if there's any kind of incline, that shifty ground makes it absolutely impossible for me to ride! down hill -- I get off and walk. Makes DH crazy!

(and I don't think losing 50-75 pounds is going to help that!)

Yup, I'm very content on the paved roads, can slime my way up just about any hill I try now, and fly down the other side of the long straight ones -- what an exhiliarating thing to do!!! (though curvy big downhills are nearly as bad as dirt!)
