Dirt, climbing on a full susp. bike takes a little different technique than HT. It's usually best to climb seated and have a smooth pedal stroke. Coming from a HT at first it will feel like you are bouncing your way up but once you get used to the FS and develop a smooth pedaling stroke this will go away. After all we are talking about bikes that only have 2 to 3 inches of travel in the back. If you prefer, you may even be able to find a bike with a lockout.
