So I spent part of yesterday trying to learn to climb steep hills on my 29er. Couldn't do it, though.

In retrospect, I think I was getting bad advice: using the smallest gear in front combined with the largest gear in back made pedaling ridiculously easy, but it also caused the bike to wheelie uncontrollably, with an occasional loss of traction at the rear. The video below at the 1:22 mark shows a rider pedaling at a much slower cadence than I was, but both wheels remain firmly planted.
