CX wheels with disc brakes
I was thinking I'd like to get a CX bike (dreaming) with disc brakes to use as a commuter and also for some road riding. Because it would be a multi-purpose bike I'd like to get an extra set of wheels.
Looking at a number of forum sponsors I don't see anyone selling 700c wheels with hubs that accept disc brakes, at least not in the 130 mm spacing for the rear hub. I see 29'er wheels but as I understand it, those wheels will not work since they are 135 mm spacing.
So is the only alternative to get some custom wheels built? Obviously there must be some 130 mm rear hubs what accept a disc brake since bikes are being sold that way, but it's hard to find the wheels.

I've yet to see a 130mm disc brake hub. I am sure they're out there but they are extremely rare.

The other thing you can do is get a CX bike with 132.5 or 135 rear spacing, which are quite common, especially amount bikes that are good for commuting. The Soma Double Cross DC comes to mind. In fact, I'm not sure I know of a disc-ready CX frame that has 130mm rear spacing.
Yet another option is to put a disc fork on a non-disc CX frame, so you've got a disc brake up front and cantis in the rear. I just did this with my Kona Jake, and I'm really liking this setup for commuting. The bike is still fairly light (about 8 pounds lighter than my old disc-equipped commuter) and I don't have to worry about the rear wheel spacing thing.

Wouldn't flexing the rear triangle create alignment issues with the disk mount?

For a 132.5 spaced frame.

I've read a few posts here on BF where people stretched a frame to put 135 hubs on and the discs worked just fine for them.
I agree with Andy though, if you can find a 132.5 frame, that would be ideal. Probably more common than a 130 I would think. Mine is 132.5.

Besides that... it's the orientation of the hub and the caliper to one another that matters... not the distance between the dropouts. The only way that you'd have a disc alignment problem is if you spread the stays so far that the caliper mounting angle changes dramatically. And 1.25mm (half of the 2.5mm total spread) is not even close to making that happen. Your steel frame would be popping welds long before you reached the caliper misalignment stage.

$100 hubs disc 700c 130mm: https://cgi.ebay.com/Novatec-D351SB-D...#ht_1661wt_905
$270 disc wheelset: https://bikeisland.com/cgi-bin/BKTK_S...ls&ProdID=1554
I'm flirting with the idea of building up a pair with the hubs listed above and white velocity aeroheads to match my tape and saddle. hmmmm.

I have a non-disk Poprad that has the 132.5 spacing so I know that it's not an issue with the hubs (I actually love this option). I don't have anything with a disk so I'm really unfamiliar with them and the tolerances.
