What causes this? It doesnt seem to happen when Im slowly grunting up the hill, but only when I am really haulling ass. Is it really as simple as being too far forward on the bike? If it is, that really sucks, because the hills I climb like this are really really steep.
Awesome power, Dude!Fredrico

The body tries to stay perpendicular to gravity, so it has to be forward over the front wheel, how far depending on how steep the climb is. The steeper the hill, the less weight over the rear wheel, the more wheel hop--as you say. You can't just scoot back over the rear wheel.

So you have to work with the bike. The first thing that comes to mind is, by rocking the bike with the hands on the brake hoods, it will meet the downward force of your pedaling, side to side, pushing the wheel onto the road at a little bit of an angle, counter-acting the direction the wheel wants to hop, right?

I knew a lightweight kid who was just awesome at this. He could climb like the devil, rocking the bike back and forth--so violently, that he broke the seat tube right above the bb shell! (It was a cheap steel frame.) Anyway, gently rocking the bike would minimize, if not eliminate wheel hop. It's just a matter of getting everything synchronized, finding good form.

I'm sure others can weigh in on this issue: honking up hills.

Generally happens when your putting your power down at the same time as you're unweighting the bike at the rear. If you've ever experienced steep, slippery climbs like cobbles - you'll see what I mean. If you ever see the video clip of Bartoli breaking away on the Kapelmuur in the Tour of Flanders a few years ago, you'll see exactly how he's having to move his weight back to stop the rear wheel from slipping.

I would agree with the other posters. One thing I would like to add about climbing out of the saddle is how inefficient it is. I certainly don't mean that it shouldn't be done and I have noticed a huge increase in my climbing performance since I have begun to climb out of the saddle but you do want to be conscious of your technique. Excessive movement of the bike, especially hopping rear wheels, is just wasting energy. Concentrate on making everything move in the direction you are travelling and try to make your climbing smooth.

Just go ride a mountain bike up some steep, loose singletrack and that will cure you right away. I think it's mostly weight balance, but to some extent it could be jerky pedaling, too. Maybe some fixed gear riding will help.

Don't start doing that in a fast sprint finish; you could cause an accident.
