[Closed] Disc specific road rims

What's out there? I'm building up a commuter so not too expensive and needs to be a fairly robust, and narrow enough to take 25mm tyres. I've looked at various 29er mtb options but they are all too wide.
The only thing I can find so far is Stan's ZTR Alpha, which are doable although a bit picey (and still quite wide!)So, what are the options?

Open pro on hope pro 2 (Hope hoops) are not too expensive or look at the shimano CX series if you want cheap.

Kinesis cx disc wheels

I already have an Alfine hub gear and a dynamo hub up front so very much looking for rims only, I'm afraid...

Looks like those rims are 20mm internal diameter. My understanding was- and things may well have changed!!- that it was best to keep your tyre width to within 1.45x to 2x the internal rim diameter. Is this still the case?

Halo Aerotrack rims are good and reasonably priced. Aero rage are also available which have a braking track but are otherwise the same and can sometimes be found cheaper

Archetype, Pacenti SL25 or Velocoty Aileron are the current favourites for wider alu disc rims. Perfect for 25mm+ tyres.

Do they have to be disc specific?

I'm running Open pros (rim/disc) with XT and Alfine for the last 5 years. Only had a buckle where the pump launched itself from the frame into the back wheel, about 5k of bumpy irish roads and curbs with a clydesdale on top.

It's what I was hoping for! Only because they look nice and I'm basically a bit of a tart haha

Nemesis those Aerotracks look good. Are deep section rims like that hard to put nipples into?

My understanding is that a 25mm tyre is best paired with a rim with a maximum of 17mm width. These rims are all 20mm plus, which would seem to be too wide. I may be wrong, I was going by the Sheldon Brown article linked above..

You get the odd nipple fall into the rim but it's easy enough to just shake them out. Just use a spoke poked through the rim to guide them in.

Fair enough - on a cheap commuter I wouldn't be to bothered - get the rattle can out and spray 'em black.

maximum of 17mm width

are you confusing inter/ external widths?

A general guideline is that the tire width should be between 1.45/2.0 x the inner rim width.

I've been running 25's on archetypes on my road bike for the past year with no problems whatsoever.

This is good to know. It'd be nice to be able to broaden my options a little...

The two colleagues of mine who have built disc road wheels have gone for different solutions. One has gone with the DT Swiss 331 29er rim which are fine for 25c and wider. The other went for Mavic road rims and painted the braking surface.

Pacenti CL 25's on my bikes. Absolutely fine with 25mm Michelin tyres.

Old fashioned advice, wide rims have been popular on road bikes for a fair few years now, archetype, A23 are the cheaper alloy clinchers, but carbon rims with 25mm rims aren't uncommon. Stans Alpha are probably the narrowest modern rim, but they get round it by having really short bead hooks so a lot more tyre pokes out which gives the same effect.
