Ahh Ok.

My cycle computer is one of the best investments to my moutain bike. I do a lot of trail exploring and marking and distance helps a lot, the wireless system dosn't get caught in twigs. I use the constant speed as a very good guide when climbing hills. Including a clock and a timer its a handy thing to have, and they are cheap to get. Average speed is the only thing i dont use because its just a stupid principle when i'm constantly stopping / starting etc, climbing and decencding.
