Weigth on a bicycle
Were does get the biggest advatage on weigth saving on a bike.
1. Wheels 2. Frame 3. Fork 4. Components 5. Losing some body weigth 6. Clothes 7 Accessiories (pump, tools, ligths,etc) I say wheels due to having to accerate and reaccerate them over many miles Charles |

Rotational weight. Tires, tubes, rims, crank. Anything you're spinning matters. The rest . . . not so much. Although none of it is going to help you much if you're out of shape!

Rephrase the question:
Q: Where would a 1lb weight loss do the most good? A: On the wheels. Wheels have static inertia AND rotational inertia. So do the cranks and pedals, but their moment of inertia is much smaller than the wheels. The chain that is contacting the chainrings and cogs do too, but you cannot lose weight off your chain. So, a POUND lost off your wheels will have a bigger effect on performance than a POUND lost off your body, frame, fork, gruppo or elsewhere. The effect will be greater the more the lost mass is concentrated towards the rims, tubes and tires as the farther the lost mass is located from the center of rotation, the lower the moment of inertia will be. |

Also keep in mind that a bike only has 3 - 4 pounds total of rotating inertia, so there's only an opportunity to at most a pound or so of rotating mass. As others have pointed out, there's usually far more mass that can be lost on the rider - and this is a typically a much more cost effective mass saving effort, since instead of having to spending more money (on new equipment), you can usually do by spending less money (on food). |

Wheels.
Shoes. Pedals. All else. In that order. dave |

But spending $ on equipment is easier than becoming fit and thin(artifically thin, according to Lemond). Too much of 'buy speed', not enough riding... |

weight is more an issue of "feel" rather than performance, unless you measure performance by bike lengths and seconds....

weight?
1)my aging body
2) my lack of flexibility, ie being more non-aero 3) wheels, I know I have noticed the difference! |

Riding downhill I'd expect you'd want to add weight. For what it's worth, I've always thought that for a given amount of total mass, greater inertia can be a good thing when doing long climbs. |
