Assuming you are talking about a 135 rear spacing you cna get ready built 24/24 CX disc wheels from Reynolds in Clincher and tubie. It's built to the assault hoop. I've also used the 29er wheelset with a file thread cx tire and it is bomber.

dbikes (Deiter Bikes) in Germany do frames as well as complete bikes.

Well priced too.

Also managed to score a def of the fork (no, he won't sell separately, a mate tried). I'll try and post it later. Weighs about 500g, and fame in a 57cm was about 1,100g

Dropout to disc remains the same for either spacing which is why you can't just put a different axle end on a 135mm hub to use in a 130mm frame.

Anyone buying/ordering a new bike should absolutely insist it's built to 135mm spacing even if the rear stays have to be a little longer. A 130mm rear disc wheel simply won't be a strong and will have more lateral flex. If you try to get the rear stays too short you might not get great shifting due to the change in chainline. I'm not 100% sure of this as I had my 'cross bike built to 135mm long before this was a consideration. It still have rim brakes (bike is 5-6 years old now), but I'd much rather have stronger wheels for the type of riding I do with that bike. With the longer stays of a 'cross bike the shifting is as good as any 130mm bike. I just haven't tried it with a road bike that has 40.5cm stays.

Since this is Weight Weenies, here are some choices in 24 & 28 hole with 135mm rear spacing, in ascending order of price :

24h
Easton EC90 XC direct pull ISO (probably unobtanium)
SRAM Rise 60 direct pull ISO (probably unobtanium)
Industry9 Torch series direct pull ISO
Hope Tech Pro 3 straight pull ISO (probably unobtanium)

28/32h
DT Swiss 240s disc (centerlock or ISO)
DT Swiss 240s straight pull (centerlock)
DT Swiss 180 Carbon Ceramic (centerlock)
Tune King (front)/Kong (rear) (ISO)
Tune Princess front/Prince rear (ISO)
Extralite HyperFront/HyperRear (ISO)
Extralite HyperCamber rear (* 32h) (ISO)

Here are some pics of my wheels that I just finished.

CM hubs, 28/32 hole 3x with Farsports 29er carbon clinchers and CX Ray spokes.

Overall weight was 1,421g

The CM hubs were 115g front and 225g rear, and are USD$170 direct from CM, but can be had cheaper from eBay.

Oh, and the advertised 78g ones (front) are not 78g. Been there done that, and confirmed with CM

I'm really happy how they have turned out.

I would be happy with 28F/32R disc brake wheelset. I think what has been bilt above is perfect but I would se Hope Pro 3 hubs.

Why Hope hubs ?

They are a fair bit heavier

Bloody keys on every keyboard I have don't work. Hope Pro 3 are 380g/pair. It's not that heavier. Also they are well sealed and let face it when are disc brakes in there element when it wet. So Disc brakes for me are for a wet weather bike.

A disc brake wheelset cold still be built for for about 1500g which is not what I would call heavy.

But this is WW ins't it :P

The CM hubs I used were 341g for the pair and USD$150 deleivered, so bang for buck is good.

Whilst I get caught in the rain a bit, I try and avoid the rain when I can, i.e. if it's raining at the start of the ride, I don't go (yes, wussy) :beerchug:

Michael - how did the road tyres fit on the 29er rims?

I use 28mm road tyres on my commuter, on Crest 29er rims and they are super-tight, so this is putting me off speccing 29er rims on my next disc-build.
