Which tyre exactly do you mean? As far as I know the only 29x3.0 ist the Surly Knard and Surly Dirt Wizard, which I guess has as well 3.0 wideness.
I don’t think it will fit. But zack28 seems to know it…
I was thinking of the knard when speaking of 3.0 and of the dirt wizard when speaking of 2.7.
I’m planing to take this frame for my next build and want to use the Maxxis Minion DHF 29x2.5. (think this one will fit … (or not?) ). Hoping that the 2.5 Minion on the 47mm KH rim will have nearly as much volume as my 3.0 Duro on my 38mm Qu-Ax rim. But it would be nice to have the option to go bigger …
The Dirt Wizard should be around 72mm wide on the KH rim
I was talking about the Knard 29x3.0 as well, but are you sure there is a Dirt Wizard 29 x2.7?
Anyway, according to ‘wendino’ the problem with the QX frames is not the width, but the length, so you shouldn’t have any trouble fitting the Minion.
I use this frame now with a 27.5" wheel and Schlumpf hub. My rim is 40mm wide. With the 3" tire (Specialized Purgatory Control) I had a little bit of rubbing when cranking hard. The wheel had to be centered in the frame pretty perfect to not rub too much. Now I have a 2.8" tire (Schwalbe nobby nic APX) and it’s perfect.
My 27.5+ came with a WTB Bridger 3.0 tire, and it fits fine. The QU-AX website says it comes with a WTB Ranger 2.8 now, but I’d be surprised if the frame had changed. Do they even sell a 29" muni anymore?
