Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

sprinting question

when i watch videos of professionals sprinting, i figured that when one leg hit 12 o'clock, the handle bar leans to that side.(E.X. left leg hit the 12 o'clock, the handle bar leans toward left.)

But When I sprint, it's opposite. When my left leg hit the 12 o'clock, my handle bar leans toward to the right.

How should i sprint?

If you don't involve the arms, all the torque that you can really apply to the pedals is your own body weight. If you pull the bike away from the side where you are pushing the pedal down you can use your arms to generate more torque and therefore more power. This would lean the bike to the right when your left foot is down, and your right foot would therefore be up (12 o'clock). I can't picture how you would do it the other way around.

Edit: I guess in your case the force of the downstroke is just pulling the bike to that side... that's not really what you want.

A way you can think about it while riding is to keep the centre of your body (midline) vertical, while the bike moves from side to side. Try watching the Tour and see how they ride when they're out of their saddles.

so i gotta push the handlebar not just moving side to side?

i don't have the road shoes yet. so i'm guessing my problem starts from there?

Well you don't push the bars, you pull them. Try to rip the bars off, that's the best way to sprint. But you will want something that securely fastens your foot to the pedal...

You pull on the bar on the side that you are pushing down on the pedal with your foot, like <umd> described. That rocks the bike to the opposite side.

It is what comes naturally. The other thing that you describe would be unnatural. If someone could even do it, it would have the rider all over the road.

No, the problem is that you are thinking too hard. Ride more, think less.

Some replies on this forum are from people who are legends in their own minds and really kind of stupid. You should get some good coaching from the team you joined. Good luck and stay safe.

Has nothing to do with the shoes. Watch some BMX racing on youtube. Those guys swing their bikes side to side in high cadence sprints without any foot retention.

Um, ok, whatever... Other than the crack about staying away from him (which would be a good idea given the likelyhood of his described actions making him a hazard to others around him), all of the replies on this thread have been reasonable.

Sho-Air/Sonance isn't really going to have coaching but Kris should be able to find some other team members who can show him the ropes, so to speak.

Those guys know what they are doing, and don't most BMX pedals have pins for grip? I think someone without experience would be best served with their feet attached if they are going to try throwing their bike all over the place.

Yeah BMX racing pedals have pins for grip, and now a lot use SPDs for racing, but BMXers have been violently swinging their bikes around long before that. In fact when I was younger and more into BMX jumping, I often used pedals without all the pins because those things tend to chew up your shins if you don't land correctly. At any rate, its not hard to sprint and swing your bike around with flat plastic pedals, if thats what you are used to.

Bolded for emphasis. My advice that Kris attach his foot to the pedal before he hurts himself stands.

No, the problem is that you are thinking too hard. Ride more, think less.
To elaborate, the rocking of the bike is more effect than cause. The purpose isn't to swing the bike, but rather to get the most force to the pedal by pulling up on the bar as you push down on the pedal.

So, OP, just pull on the bar on the side that you're pushing the pedal down, and all the side to side stuff will take care of itself.

Also to accelerate your cadence by shortening the distance while you move your foot from 12 oclock to 6 oclock by rotating the bike side to side.

??? Your feet remain in the same position relative to the bottom bracket no matter how you tilt the bike. Thus the arc your foot travels can't change by leaning the bike back and forth. Unless I'm missing something this makes no sense.

I experienced that a lot as a kid doing jumps all over Golden Gate Park in San Francisco. I think I grew accustomed to the pain from enough bad landings during middle school years.

I don't really even think that's possible to do without defying some law of physics (or just falling over). I would find someone from your new team, and pose the question, so they can ride side by side with you and help you. It seems you need something more visual to grasp it.
