pulling back wheel off the ground...(4 posts)

pulling back wheel off the ground...wulf
Jun 7, 2002 9:06 PM
This may be a stupid question, but I'm new, so please humor me.

On Monday this week, coming around a gently bending, very slightly uphill corner, I stand up and start sprinting away (my version anyway). It took me about 15 seconds to realize what had happened, but in my enormous strength (ha, hardly), I had lifted my back wheel off the ground. It happened again tonight.

Now, is this due to a really crappy stroke, meaning that my pulling on the up with foot (a) was far greater than my simultaneous pushing on the down with foot (b)? That is my first thought, but I don't know. I didn't wipe out or anything, but it freaked me out a bit.

What did I do wrong?

Sounds like you have a weight distribution issue to me. Try and keep your weight back over the bottom bracket more when you stand up. In other words, don't lean so far forward.

You'd really notice this climbing on wet hills because the rear wheel would be breaking loose a lot- a real waste of energy.

as the other person said - try keeping your wt over the BB. Leaning right over the handle bars also causes the front wheel to grind into the pavement . So not only are you not getting sufficient traction on the rear, you also have too much rolling friction on the front. The difference in efficiency is even more prominent if you tend to inflate the front tire is little less than the rear.

if the road is uneven and you are sprinting full speed already, your back wheel will suddenly move to the side because you are going over them bumps so fast your wheel has no time to connect on the ground. It moves to the side because you apply force on one side then the other, understand? If freaked me out a little bit until i figured out why that happened.

If it just lifted off the ground it must be too big of a gear for an initial acceleration. A better way to start a sprint is not push monstrous gears but put it into an easier gear and spin up smoothly and as fast as you can. Experience told me that you are better off spinning in a sprint than mashing. You'd probably save a little bit of legs. Once you are about to run out of gear shift up a cog or two, depending on the incline and mash away!

I don't follow that though :--0

Woof the dog.
