Hello-
I'm just starting to mtn bike and have some questions on technique. I'm a roadie (serious road rider = never had to maneuver any climb/descent that wasn't flat and smooth). This is a whole new ballgame, and I'm figuring out that I know NOTHING about mtn biking. I'm riding beginner trails now for a change of pace (not too steep descents/climbs/obstacles), and have some questions about how to handle climbs/descents.
I've read that when descending, to put your weight back (the further back the steeper the descent), is that right? How about climbing up? Do you put all your weight forward (while standing to pedal)? Is there a right/wrong way to climb (in saddle vs. out of saddle)? Is there a technique for riding through deep sand (aside from my current technique of fishtailing and then walking my bike to a harder surface)?

Sorry for so many questions, but I think I really like the change of pace that mtn biking offers (and it works totally different sets of muscles in both my upper and lower body than road riding). I just need to figure out some tips to make it a little easier (and prevent me from walking so many ups and downs). The downs terrify me, and the ups intimidate me.

Oh, and I'm riding my Target special right now (hardtail, not clipless or cages). My tri lifestyle won't allow for another big bike investment, but I think I may add clipless shoes/pedals to my mtn. bike for better control. It's a hardtail, but has decent front suspension (aside from the fact that it's 200 lbs heavier than my road bike).

Thank you for any advice!!!
