Weight Loss and speed increase

Bozabyka

If a cyclist weighing twelve stone rode ten miles in half an hour,
How long would he take to ride ten miles if he weighed eleven stone?

This is without doubt the stupidest thread i've ever seen on this forum. so hats off sir.

Is this a quiz?

Bozabyka

So we spend all this money on lightweight components and loose weight to increase our power to weight ratio yet we cant measure the gain?

Graeme Jones

29:59?

the answer is 42.

depends on body composition and gradient. on a flat TT course no difference. Possibly a few seconds on a gradient.

Experiment: amputate one leg.

If you lose a stone then you may well lose some muscle mass as well as fat.
It will definitely help on the climbs though.
I have a mate who is 2 stone heavier than me. He rinses me over a 10mile TT but I have the upper hand on the hills.
It should also help acceleration as well.

I don't think anyone can give you accurate figures though

Yes, but you only joined recently

Courtesy of this site http://www.analyticcycling.com/ and assuming that all circumstances are identical, you would gain 1 minute 48 seconds over a completely flat 10 mile time trial.

Easy.

11/12 x 30 = 27.5 minutes

Depends on how you go about loosing the stone ...

I've lost a stone and gained muscle mass ..

Speed increase as a result? yup - but not something you'd measure as a result of weight loss - it's fitness that's improved the speed.

Losing muscle makes little odds to becoming a faster cyclist, as has been said on here time and time again. You don't need big muscles to be a fast cyclist...

Around 9 seconds quicker assuming no wind, no gradient, riding on the hoods with a 20 lb of bike + equipment and with the same power output and drag coefficient.

If it hasn't gone mouldy, I'd go ahead and eat the cake...

I have heard 1mph faster per 6kg loss quoted provided you don't lose power output with it.

There is a great app called bikecalc which could do the maths for you if you play about with it.

Depends where you live.
Cambridgeshire - F.A.
The Dales - quite a bit.

Yeah, Chris Hoy is just showing off with those quads.


Sometimes you do need more muscle. Clearly the same does not apply on a hilly race. I think u get what I'm trying to portray here.
