Skidding: difference between track and road frame

God is really dog, and snoops is really spoons. It's a mixed-up, muddled-up, shook-up world, except our forum.

Where's your forum Ollie?

...sorry.

jesus was a keen horse rider

He did like walking, by all accounts.

jesus was a keen horse rider

would agree with that

Jesus was a black man, according to the film Dogma. (awesome film)

I thought Rufus said Jesus was a white man and yes awesome film.

Where's your forum Ollie?

Got the quote completely wrong. Fixed now.

i think you misheard, he's a capricorn.

oh i do apologise

I got overtaken by a couple of swans down by the river the other day... was well pissed.

jesus was a keen horse rider

he rode an donkey

not an horse?

he rode a benz and could rip crab mcs in half.

wait. no. that was eric or parrish.

why can't I skid on my pista..... I'm not a pussy even!!

Are you sure about that?

It's down to skills.

I don't see how the shorter wheelbase answer works.

To make skidding easier less friction is required between road and tyre.

Friction is proportional to the force perpendicular to the surface.

On a really long wheel base bike, the reaction acting through the rear wheel is decreased and so it is easier to skid.

This can be seen by riding a tandem with on one on the back, you can skid really easy.

Using this we can say that it is actually easier to skid on a longer wheel base slack geometry road bike. So your inability to be able to skid your conversion was a skills thing.

long wheel base and road forks - try to skid brick... it is everything to do with short wheel base and forks angle + transfer of rider's weight towards front wheel when about to skid...
you talking about skid when using brakes and not cranks...

Tommy - I think it is more complex:
1) Shorter wheelbase would make it easier to unweight the rear wheel, as you do not need to move your weight as far for an equal reduction in normal (perpendicular) force.
2) if you use a front brake to initiate a skid, then the moment (around the front wheel contact patch) will lift the rear wheel more easily with a shorter wheelbase - because the centre of mass is closer (further forward) than for a longer wheelbase... roight?
The tandem thing occurs because the lack of stoker means the centre of mass is much further forward than otherwise..
Please excuse my a-level physics thought-experiment jibberish.

No you are wrong. Even if you are throwing you weight right forward a longer wheel base will still have less force traveling though the rear wheel hence easier to skid.

Maybe it's to do with the stiffness of the frame? Has this been covered?

If the frame is stiffer around the bb then less energy will be spent in bending the frame and more should go towards stopping the rear wheel. I believe track frames are built stiffer around the bb and with a shorter wheel base then there road conversion cousins, so there is less chance of flex in the frame meaning that a higher proportion of the force you put through the cranks should go to the wheel, this would only really apply when large forces are being transferred such as initiating a skid or doing a standing start. This could of course be toss but it seems to make sense to me. If you give your bb a push with your foot you can see how much it flex's and then compare it to a track frame/road conversion there should be more flex in a road frame I believe.

maybe, just maybe, it's to do with how well developed your leg muscles are.

Are you mad?! Don't be so foolish!

I thought Jesus rode a Triumph? Or was that Moses?
