    American Classic has sold production 650b wheels for at least 3 years. They do have different looking labels this year.

    Yeah, that is odd. The article and Interbike show make it sound like it's their latest and greatest. I guess why reinvent the 650b wheel when you can slap on BNG.

    I think the 27.5 Race version is new though, isn't it?

    The Race wheels are new, the 650b wheels from last year were OE spec only (not light).

    I have many troubles with keeping the correct bearing preload on my 26" American Classic/Stan's 347's. One ride they work perfectly then the next ride they seem too tight and the pedals spin when I push the bike. These are 08 version and this may have been corrected but that's what I've experienced with them. Super light at 1380 grams.
    Too many bikes, and just enough time to ride them.

    ACs are supposed to be set up with a very small side-to-side play when they are not torqued down with the quick release. This is in their literature.

    Ah, thanks for that info. I try to get zero side to side play before install. This will make me a very happy camper, great hubs and rims I have to say.

    I'll try to find the little pamphlet they come with. It's small and one of those got lost in the box items.

    Just got back to the US. Thanks for the tech data, I'll readjust accordingly. I was beginning to call these crap or at least not worth the money spent but they are sexy as all get out....

    That is very good info. I was worried about the side to side play in my AC rear hub and torqued down the 19mm nuts. I will ease that up as noted.

    Do you know if the 15mm thru-axle front hub is different? I have a small amount of play in that hub as well (although I don't have the wrench to tighten that one).

    All I've seen on their website:

    I have been told that there should be a small amount of play in my bearings, is this true? We recommend a very small amount of play be present when the quick release is loose for our rear wheels. Once the quick release is tight in the frame there should be no play (a whisper of play is fine). The purpose of having this play is to extend the life of your bearings and reduce friction in the hubs
