Back wheel off ground while climbing or sprinting...(9 posts)

Back wheel off ground while climbing or sprinting...jtkirk15
Apr 25, 2003 9:34 AM
Sorry if this has been covered many times before. Recently when I have really hammered either in a sprint or up a hill, I've noticed that the back tire is lifted off the ground. I can't imagine that this is as efficient as possible. Do I need to shift some weight back? Ideas?

Oh yeah, this is on a road bike. Thanks.

It's natural to rise up and move up over the cranks, but you have to resist that impulse. If you skip the back wheel often, you have to stay back as far as you can while standing. I tend to have the opposite problem while powering up a hill. The front end unweights and stearing gets funkey.

you bounce too much on upstroke when stand. Shifting weight back doesn't help since it is you going airborne and lifting bike alone. Try to control amount of effort you put in upstroke good luck

Thanks, I thought it was a combination of the two. When I hop out of the saddle I always focus on the upstroke for power because the downstroke is the easy part. I will try to smooth the stroke out and maybe push my weight back just a little. Thanks for the ideas.

on small, very steep hills focusing on hammering with mostly the upstroke is a good way to rest your legs AND use muscles that have been otherwise been well rested. it gives your climbing muscles a break. as long as you know you have that problem (rear wheel lift), you should be able to concentrate on it and control it before it happens. nothing wrong with concentrating on the upstroke for brief respites though.

Your weight it too far forward. Try to center yourself more over the sweet spot of the bike. This is especially important coming out of corners, too much weight on the front of the bike and your stearing will get wabbly. You will not be able to recover from a slide either.

Also, calm down a little when you sprint or climb. Focus more power on a circular powerfull stroke and less on flapping your bike back and forth.

Try some sprints in the grass and or gravel. You will learn quick or be eating grass/gravel.
cast iron frame should do ya. nm.stinkfoot247

Nix to the cast iron frame idea. Too expensive to change your whole bike just for a simple upstroke problem. Try this: take out the seat post and fill the seat tube with lead shot. Works great!
sounds like you need a trunk rack and carradice bag. nmJS Haiku Shop
