Does anyone happen to know the weight of the Wolber Aspin tubular rims that came on the '84 TdF's? I have some Mavic GL 330's with Campy hubs and one GL 280 for the front that I'm tempted to put on my frame but I don't know how the Aspin compares in weight to the 330's. I know the 280 was one of the lightest tubular rims in it's day.

Scott,

http://weightweenies.starbike.com/listings/components.php?type=rims
http://www.sheldonbrown.com/rinard/weights.htm#tubularrims

Mavic GEL 280 Advertised Weight 280g Real Weight ~303g

Mavic GL330 Advertised Weight 330g Real Weight ~340-350g

Wolber Aspin Advertised Weight 345g??? Real Weight ~360g to 365g

My favorites were always Super Champion Arc en Ciel rims, ~350g

Thanks for the comparisons, Chas.

I've never quite understood why advertised weights are never, in many cases, in the close region of actual weights, particularly as the manufacturing processes allow for very little tolerance. The degree of difference is often greater than expected, particularly for complete bikes.

Does anyone have any thoughts/experience on this one?

Tim

PS Nice rims, Scott.

I should have known Sheldon would have the answer. Smile

Might have been due to the spoke count (?).

I know that with bicycle frames, some manufacturers will publish the weight based on a 48cm frame. I have to imagine that the most "common" or "popular" size frame would have to be in the 54 to 58 range. There is no industry standard for this though.

Truth in advertising has never applied to bicycles. Many times rim weights are listed without the ferrules - DOH!

There was a time when tire manufacturers marked the cross sections of 700c tires 1-4mm larger in diameter so they could say their tires weighed less than the competition.

For example, 700x23c tires that were actually 19mm or 20mm, 700x25c that were 22mm and so on.

As long as "weight wienies" drive the marketing forces in the cycling industry manufacturers are going to pander to that segment of the customer base.

I figured it was something like that. So take the rim, don't put in the ferrules (sp?), then weigh the one which takes 36 spokes...and boy is it light! Better yet, if there is a 650c version with 120 spokes (the infamous "drillium" rim?), weigh that one!
