A friend of mine who I meet up weekly with at the track has a new Jamis Sonik. His wheelset supposedly weighs 1600 gms. His American Classic rims are listed at the same weight as my Mavic Open Pros and although he has less spokes I couldn't see how his rim set could weigh 400 grams less than the ones I built up. I have the standard high flange Formulas which I consider to be functional and maybe slightly heavy but when I checked the specs a pair of Formulas weigh 250 grams more than a pair of high flange American Classics. Now I know that weight in the hub is less important for a spin up than weight in the rim but how is it even possible to manufacture a hub which is so much lighter for a given function? Aluminum is aluminum and steel axles are steel axles ... could the American Classics be defying the basic rules of physics? These things actually weigh less than some vintage premium low flange hubs I have on my road bikes.
(note - I did reduce the weight of my wheelset almost 30 grams by cutting off the excess axle width that stuck out on either side of the rear track nuts but that still leaves his hubset weighing 220 grams less than a pair of Formulas),
