I am buying a new full suspension bike for XC very soon. I am toying with the idea of a 29er. I have never ridden one, so I'd like to ride one a little around a trail before I make a decision. I have tried a few shops and the best that they will do is let me ride it around the parking lot or could potentially arrange something in a month. Are there any shops or people who would be willing to allow me to ride on groenkloof or some other track that has at least some technical bits? Ideally I would like to test a XL, but a L would do. If it helps, I am thinking of the Silverback Mercury 26 or 29. A small token of my gratitude:
