perhaps a dumb question ... but ;-) i am looking to build up some new
wheels. i have a hardtail with disc brake mounts but still use the
v-brakes. can i use hubs that are for disc brakes - but still use
v-brakes (with the right rims of course)? i dont want to pop for disc
brakes just yet, but would like to be able to upgrade to disc without replacing the wheels/hubs later on...

Disc brake wheels need a much higher spoke tension.. I guess it shouldn't be a problem with a high quality rim. But still, that could be a issue.
I'd say go disc brake all out and get proper rims made for discs.

Of course.

I did it.
I run my hope xc hub and 717 rim with v-brake before.
You have two more options that you can upgrade to disc later on or sale your hubs.
The disadvantage is the slight weight penalty.

BULL-SHE-IT! Disc brake wheels need proper tension, just like rim brake wheels. The tension is not any higher.

Radial spoke lacing should not be used on disc wheels. Other than that, wheels are wheels.

I've never had a bike with such tightly tightened spokes as this disc brake bike..
But actually, this very site suggests high spoke tension =)

Yes, it does say to use high tension in the "Common Sense" section.
It does not say "...Disc brake wheels need a much higher spoke tension..." than other wheels. Well built wheels always have high spoke tensions.

On a side note, the fewer spokes in a wheel, the higher the tension on each spoke.

Well, me too ...

I just got my new set of wheels. I ride with Vs but wanted to keep the disc option open.
Built the DT 4.1 on the new LX hubs. the hubs are CenterLock so the weight penalty is minimal.

Alrighty then, oh mighty god of spokes =)
Guess I've never met a bike with good rims and v-brakes before =p
