/ Is losing a Kg around the waist the same as off the bike?
Aside from the fiscal benefit, are there any benefits for the average middle-age punter, to loose weight from the bike rather than around the waist?
Rotational Mass (i.e. the Wheels and drive train) make quite a difference to your ability to accelerate, and more so than loosing a Kg off your seatpost or your belly. Having said that to save 1Kg off a pair of wheels is going to seriously cost you.
Always better from a performance point of view to loose the weight off your belly first. (But a nicer bike may encourage you to ride more and loose that belly fat too)
"Having said that to save 1Kg off a pair of wheels is going to seriously cost you."
On my MTB I realised that the stock tyres were crazy heavy steel bead monsters so managed to scrape a kg off the wheels just by changing the tyres.
Same could be said about low range road bikes, the differences aren't quite so large but you could save quite a reasonable amount off by changing the tyres.
You'll also be limited in how much lower you can go with the bike weight - at £1500 you can probably get a sub 9kg bike and the UCI minimum weight limit is 6.8kg, so unless you intend to take a drill to it as some domestic climbers do, you won't lose a huge amount.
Loosing weight around the waist can make a big difference to your day out. It will make your body more efficient (fat people burn more calories than thin people for the same activity as a simple example), nevermind the health benefits you'll get.
Chris Boardman's coach computed that a loss of 1.5kg body fat would give a 46 second advantage over a typical 1 hour climb (8%). Over the tour that would equal 7 minutes.
46 seconds? hmm, not sure thats worth me giving the pies up for!
Thanks for responses though guys. I've a bit of a pact with her indoors that if each of us achieve our target weight, we can have a bit of a treat. I just wanted to make sure that if mines comes on two wheels, it's worth the agony!
I've dropped nearly 6 kg in the last few years after getting back into mountain biking.
Fight the middle age spread and you'll feel (and probably look) so much better for it. And biking will be more fun and easier, the fitter and lighter (within reason) you are.
Buying a lighter bike is just cheating ;-0
similar really - dropped to 72 kg but the last few Kgs are holding their own!
I don't eat pies. Maybe I should :)
Looks like we've had a similar middle aged journey then! 82 to 76kg
I don't want to get any lighter now, just want things to move upwards to where they used to be ;-)
If you're a few kilos overweight and you're training hard the weight will fall off, you'll get faster and your improvement will be exponential. It's an amazing feeling. Combine this with chopping a few hndred grams off your bike and you'll never look back.
PS - Come on guys, lose and loose - please look it up ;-)
If you are cycling for fitness, go for a flabby bike.
If you want to win the Tour D' France, buy something lighter.
