I have a 26 inch MTB.

I am thinking of converting the rear to disk brakes.

What kind of rim would I need?

Thanks.

Practically any 26" MTB rim will do. The difference between rim brake
and disc brake specific rims is usually that the disc brake version
doesn't have a surface for rim brakes to work on - but it doesn't matter
if you use a rim designed for rim brakes on a wheel with a disc brake.
In fact you could use such a wheel in either rim or disc brake bikes!

Braking forces act from the hub through the spokes to the rim and tyre
with disc brakes. Make sure you have at least a 3x spoke lacing pattern.


How will you mount a disc brake calliper to what I presume is a rim
brake equipped bicycle frame?

Not correct. I would needa rim with a spot to mount the disc for starters.

WTF?? That's nonsensical.

A disc brake grabs the _rotor_, not the rim. That's the
whole idea!

One may use thin laminated carbon fabric for a disc brake
rim which could not bear the heat of a rim brake.

But a chunk style XMart metal rim, made for rim brakes,
would function just as well if built into a disc brake wheel.
