Magnesium clincher road wheels spotted...(12 posts)

Magnesium clincher road wheels spotted...MikeFL
Oct 6, 2003 11:40 AM
Hello all,

I was riding in Tampa, Florida over the weekend, and went on one of the organized rides closeby. Bill Shook from American Classic was there, as well as one of his sales guys. Bill told me AC are working on magnesium clincher rims at the moment, but are still in the testing phase. The other AC guy there had them on his bike... 1207 grams for the pair, 28 front, 32 rear, with DT revo spokes and AC alloy nipples! Crazy! Bill was telling me they believe they can get the wheels to sub 1200gm when they reach production... very cool.

Some photos I took are attached. The wheels look pretty trick and I like the new stickers they have for 2004. The guy's bike they were on tips the scales at 13.1lbs, and that's with the mag clinchers... another weight weenie.

I don't care about wheel weight, tell me about rim weightKerry Irons

There are many "dirty" tricks that can be played to get wheel weight down, but they typically compromise performance in some way. There are way too many stories of "super light" wheels where the hubs fail or spokes pull through, etc. The real question is whether they are able to build a reasonably durable clincher rim, where your brakes will work, at significantly lower weight than can be done with aluminum alloys. CF rims save weight but the braking is sketchy and so far you only save significant weight with tubulars. BTW, back in the day, 280 gm tubular 7075 aluminum alloy rims were readily available from Fiamme and others. These were typically reserved for front wheels or light riders or events only, but building a tubular rim that light doesn't impress me.

Kerry, I'm familiar with those older lightweight rims. I did forget to mention the rim weight in my first post. Between 294 and 298 grams, and that was the word from Bill Shook himself. Very impressive for a clincher rim. I am looking forward to AC releasing this product.
So maybe 10 gm lighter than Velocity Aerohead?Kerry Irons

Doesn't sound like much of a breakthrough.

several things i've worked out about kerry irons is... he's (a) a know-it-all who knows f-all, (b) bitter (c) cheap (d) bald (e) stupid. aeroheads weigh over 400 grams... these guys are claiming sub 300gms... maybe you should stick to posting with the other forgetful old farts on cyclingforum.com

lol, because you're so cheap, this sort of thing wouldn't appeal to you anyway... probably cost over $100... i know you like to milk at least 50000+ miles from a set of handlebars... cheap

even the bull's postings make for more interesting reading than the piffle you post

Aeroheads are 405 gram rims.... so they are 110 grams lighter.russw19

There is a set of wheels in one of the Italian mags, 474gm front, 606gm rear (1080gm/pr). So the AC wheels are too heavy.
clincher? nmDougSloan

The rims used on the 350 wheelsets weigh 350 grms. The rim weight of the 420 wheelset is 420 grams.

I bet the weight of the "300" is 300 grams.
