Bike control when sprinting

chakattack

Practicing a few sprints over the weekend and my back wheel was jumping all over the place.

Any tips?

I doubt that the initial "jump" was too hard (or can be!) and I was using the drops.

Is it possible that your back wheel was spinning on a greasy surface?
For your back wheel to be bouncing...either means you are doing it wrong or something isnt right mechanically
Effectivley (presuming you are outta the saddle) you should be pulling on the bars as you pedal.

Work on your core stability and this should help. Practice I suppose too. Hard to judge the initial kick as you do want it to be as hard as possible but if it's jumping about will reduce speed.

That is normal in the wet but Sat + Sun were dry so don't lean too far forward over the bars in the acceleration phase. Small bumps on the road can cause the back wheel to bounce a little too.

when you sprint , its important to pace yourself

Ie you want to build it up like a crescendo

practice sprinting between two different markers (signs,lampost etc)

are you using tubs? are your tires worn?

I find the most sprinting(end of races) ive done, last year, were on a slight incline.

let me know

Like Victor said it was dry, maybe leaning forward too much at first.

Practice and trial and error I suppose.

Thanks all

Almost new tyres and clinchers. Pan flat road. I practice them on inclines too but don't have the same problem.

I try to jump as hard as I can, then accelerate by going from 80 to 120+ rpm and then hold it as long as I can.

Maybe I shouldn't worry so much about the jump part. I'm losing traction and speed because of the wheel jumping.

Keep your shoulders behind the hub on your front wheel.

If you're standing up, your cadence shouldn't be that high. 120rpm means that you'll waste a lot of energy just maintaining stability. If your cadence goes over 90rpm then either drop a gear or drop into the seat.

When standing, aim to minimise the side-to-side movement of the bike. This delivers maximum power while sprinting with maximum stability.

for clothing, esp for commuting, I recommend using merino wool. It's got good insulation properties and is pretty stink-free.

Urban Frog is an Irish company selling them online (also in some retailers, on sale at Joe Daly's in Dundrum if that helps).

Also recommend using panniers if you're commuting. I find it a lot better than having a backpack stuck to me. I have a slightly cheaper version than this, holds laptop, change of clothes, make-up bag - the essentials

Wrong thread? Which one would you like me to move it to?
