I plan to get a set of wheels biuld for my mountain bike.
I've checked the clearance and I can fit 700c wheels.
I use disc brakes so the placement of v-brakes is not an issue.
I'd like to biuld a light wheelset that is able to take the additional stress that disc brakes place on the wheel.
I'm 80kg and ride a 15 mile road commute 5 days a week. I dont run a car so I'm saving £300 UK a month. This and the 600 + miles a month, mean I can justify £300 to £500 UK on a wheelset. I'm also really keen on getting the weight down.
Thanks in advance for your help and advice.

I have a hardtail MTB and I´m using a wheelset with DT-Swiss Onyx Hubs (Disk), 32 spokes and a Mavic CXP33 rim. I have Conti 23 mm Clinchers on it.
No problems at all. Best of all: When you travel and take MTB wheels and roadwheels with you - you have 2 bikes in one
The frame will fit 700c wheels comfortably.
The fork has bags of spare room.
I know plently about MTB hubs.
My knowledge falls down in the area of:
What spokes will take the additional stress of disc brakes?
What 700c rims are both lightweight and suitable for disc brakes?
I had some wheels built like that exactly. I built up a Cannondale Cyclocross Disc bike last fall for riding in the winter and the rain in the City(I live in Toronto Ontario Canada). It has 135 mm (MTB) rear spacing. I ended up using Mavic Open Pro Ceramics(Look Great and because your running Discs you don't have to worry about ruining the finish, about 430g each), with DT Super Comp Spokes, reasonably light at 318 grams for 64 and I'll quote DT "With the DT super comp, you can build perfect wheels for bikes with disc brakes. The triple cold-forged DT super comp withstands the most extreme loads. Butting of the middle section saves additional weight.
DT super comp is ideal for disc brake bikes, freeride and touring. Black and 100% Swiss made".
I used brass nipples 65 grams, and used Chris King MTB hubs(166g front and 306 grams rear ISO). I used 32 spokes in each wheel crossed 3x.
Total weight is about 1,706 grams, not ultra light, but not bad. I've put about 1,000 km on them bashing around the city and they've been perfect. I weigh about 220 so I can easily feel if there is any flex(I had some Kysrium SSC and they rubbed the brake blocks when I was standing on my road bike), but these have been great.
If you want to make a lighter set use fewer spokes in the front and use alloy nipples, and you should be able to get down to the low 1,600's.
