Just got my hands on a set of the CR350, actual weight is 530g front, 760g rear, so 1290g total. Pretty light stuff.

American Classic is how their spokes are non proprietary... I haven't ridden a set of those Topolino wheels, but I imagine those spokes (an entire half) would be pricey to replace. AC is using DT Revos and Comp spokes, which are easy to obtain. And, of course the 350s are way lighter both in weight and damage to the wallet... I do like my set :)

does the rear rim of the new cr350 have off center drilling?

No. Both rims are standard.

Tri-flange... what a marketing gimmick that is

Not really, the tri flange design gives more even spoke tension on the load bearing hub.

and torque transfer???

Well yeah, thats the point of the equal spoke tension and transfer of power.

---- posted from another forum in reference to the 3 flange wheel ---

Most hubs have too small a section diameter to transmit much torque to the non-drive side spokes. The wind-up of the hub prevents the NDS spokes from gaining enough tension to be effective. Hence the drive side spokes typically transfer almost all of the torque to the rim. Similarly, the flange in the center of the hub would have the same problem unless they made the hub diameter very large, which they didn't seem to do in this case. Granted, it would theoretically be able to deliver double the torque of the NDS flange, but double of close to nothing is still pretty close to nothing.

Edit... I just took another look at the hub pics and now realize that they are forcing the torque to the center flange by lacing the drive side (and NDS) radially. This negates any ability to transfer torque on the DS so all the torque is essentially driven by six spokes (only three pulling). Wow!

HOLY CRAP!!! Just talked to my inside source today after reading a post by someone that a 300g magnesium clincher is comming out. IT'S TRUE!!! A 300g clincher is comming out from american classic, but unfortunatly it's only going to be a race day only product due to the corrosion of the magnesium on the brake track.

ALSO!!!! To complement the new mag rims, and all other current am classic road wheels NEW HUBS ARE COMMING!!! Front hub will weigh in at 61g, rear 183g!!! HOLY MOLY!!! 50g weight savings!! And a superior design and made by a more reputable manufacturor. These are gonna be sweet. The may or may not be at Interbike this year, but if the are not the will most likely be available next Spring! I can't wait!! A 1140g clincher wheelset, for race day, 1240g for everyday!! :P
