So, just before the standards changed I finished building a very fancy TD bike with 9mm dropouts that I now want a new rear wheel for. I can't seem to find many nice 9mm hubs anymore, but I'm finding wheels that come with a 10x135mm QR.
I'm optimistically hoping that "10x135 QR Included" means I can adapt this hub to fit in my 135mm frame?
What exactly is meant by 10x135mm QR?
Technically, disc brake mountain bike quick release rear dropouts hold 10mm in diameter axles and are 135mm wide. Most front quick rease front forks take a 9mm axle. So please double check if you do really need 9mm axle on the rear, I doubt it does, but I don't know which bike you have.
10x135QR:
Most non-boost (12x142mm) thru axle hubs can be converted to 10mm 135mm QR.
If the hub says it includes the 10x135QR, then it will fit the starndard 10mm 135 rear dropouts.
Most hubs that have interchanbles end caps are simple to change, see this short video as an example.
Here is an image with different end caps for Koozer XM490 Hubs (front and rear) which change the spacing of a hub to suit different frames and forks:
The AI most likely refers to Cannondale's asymmetric integration. It is very beneficial: the rear of the frame is made asymmetric to make spoke tension on the left and right sides almost equal. However, if your bicycle does not have asymmetry in the rear of the frame, don't buy such a wheel. It will be off-center on your bicycle.
If you don't find a suitable wheel, fear not. Separate hubs are still sold and used. Buy a 36-hole Shimano rear freehub, a good 36-hole rim with sockets ("double eyelets"), and have a professional wheelbuilder build a traditional 36-spoke wheel with high quality butted spokes and brass nipples. It will outlast any machine built wheel you can find on the market.
