    I used my Magura HS11 brakset and measured:
    ~30mm between the mounting bolt and the brake pad at max extension + 27mm Rhyno Lite rim width + ~30mm (other pad to bolt) = 87mm (maybe 90mm) max width between your Magura mounting bolts for this rim to work on your frame.

    It would be easy enough to test for yourself - just mount up your maggie brakes, adjust them to max inward position/reach, and measure the gap between them.

    I sold my drak frame so I couldn't measure the mount width on it, but the unis I do have (nimbus 24, 26, and older KH 24) all had almost 100mm between the mounting bolts. I know the Drak had a narrower profile than these unis, but I'm starting to wonder if maybe I didn't actually run the Rhyno with the maggies.

      Maggies With Rhyno Lite

      It was bothering me to the point of distraction, so I mounted my Magura HS11 onto my nimbus steel 26 frame and they do fit the Rhyno Lite (plenty for grab). Whew! - I'm not crazy.

      I did have to mount them as far in as they would go though.

        Distance between Magura mounting bolts on the Nimbus steel 26 - 97mm.

          Thanks for taking the time to do this!
          That's good news, what I would save on the brake extenders (reducers?), I would spend on the rim. Why not hey!
          This rim is at a decent price, even new. Now I need to figure a way to bring it back in Europe as I don't know if it would fit my regular suitcase...

            I discovered another wide 700c / 29 rim-brake compatible rim in a 36 hole option:

            The Velocity Cliff Hanger - 35mm outer width (slightly wider than the Rhyno Lite) $65 -85

                Yes but it's a non-disc brake rim, and it's even wider. So whilst it's good news for our munis, it won't help my specific setup.

                  Dear Pierre, this post is related to 29 rims, not only your concern ;-)

                    To be fair, Pierrox is the OP of this thread and it's clearly about finding a narrower rim than KH rims for his G29 project, rather than talking about 29 rims in général.
                    Maybe the title of the thread is not specific enough.

                    29" Rim
                    I'm looking for a rim to move my Schlumpf hub into my 29" uni. I'd rather build a new wheel and go narrower than the KH rim as it'll be for road/town use.
                    It would have to be compatible with Magura brakes and have 36 holes to match the hub.
                    New KH rims will be even wider than what we have now, clearly not matching his project.
                    - Geared kh36 + Nightrider Lite + Kh Tbar + HS33
                    - Qu-ax 36" + nightrider +Q-handle+ cable rim brake
                    - kh 29" + knard 29x3+ kh Tbar + HS33
                    - Qu-ax trial 19"
                    -24"&26" wheels and forks and spare stuffs.

                      What about the rims spec'ed on QX unis?
                      Or even the Alexrims DX32 that is found on the regular Qu-ax muni?

                      It is a rim strong enough and in the 32mm ballpark. And they have several different drilling including 36H.
                      => CrMo 29: KH XC rim, Nimbus CrMo hub, Spirit 110/137 & Schwalbe Big One
                      => Flansberrium 26: Nextie rim, JumboJim 4.0, Spirit 127/150mm, M4O ISIS

                        They're 40mm. (The Plus size ones are wider)

                          Just for future reference... here is what I did with the brakes as the pads couldn't reach the rim I settled for (a Rigida Sputnik)!

                            Is that really too big for this rim? I read a lot about rims lately and with the wave of fatter tires on MTB, it seems acceptable to go that wide on such a rim. But real life - and unicycling - has different rules.

                            Do you think this rim would work? What would be another choice?
                            I ran a Schwalbe Big One 2.35" on a H Plus Son Archetype rim at Unicon 19. It was good enough to come third so I guess it works just fine.

                            The rim is pretty strong, didn't notice any flex, and has a braking surface. It is slightly narrower than your Mavic at 23mm. The deeper profile silver finish looks really good though.

                              Thanks for the feedback!
                              I kept my Big One until recently. I loved the look of it, the light weight, how I could fall into a turn with it. But I hated that it got 4 punctures in just a few months - the only uni I ever got a flat on. And I didn't like how it reacted to road camber, and even to tarmac patches (when they fix a part of the road and you ride across, almost parallel, to the joint between the old and new tarmac).
                              I'm clearly nowhere near you as a rider, but those were too much to cope with for me and I wen't to a narrower Marathon.
