The other day I took off work and set up a solo-shuttle system using my cross-bike and the Element.
As I pulled in to Windrock, I locked my cross-bike at the bottom and drove to the top. Geared up and hopped on the downhill bike, and switched bikes at the bottom, then made the climb. Repeated this twice, then packed it up and met DJ at Haw Ridge.
I rode three different bikes that day. Cross-bike, Downhill bike and the singlespeed. Damn that's a good day.
