    29+ wheel height compared to 26x4.8 on 80mm rim

    Hi guys, with the current 29+ craze especially with news of the coming Jones 29+ frame..am thinking of combining a fat front wheel to a 29+ rear wheel.

    Question is, will the height be equal, higher or lower with these two wheels comparison?

    Am currently on a Marge lite rim with Surly Nate front wheel and a 29" rim with Ardent at the back. The fat Nate is lower in height compared to the 29 Ardent at the back.

    Can anybody do up some measurement of a 29+ Knard wheel height and a 26x4.8" Bud tire on 80m rim?

    Thanks.

    The 29x3 Knard is 779mm tall on a 50mm wide rim.

    The tallest fatbike tire is the Bud 4.8 at 762mm tall on an 82mm rim.

    Oh, ok thank you for the link...

    Looks like the diff in height is quite significant...looks like a no go then.

    It's only 17 mm taller. Divide in half and you get 8.5mm vertical distance between the hubs.

    Yep. If you have a choice of forks use one slightly longer. Otherwise don't wworry about it. It isn't much of a difference.

    Or can put spacers below the htube rather than top to bring the height up.
    Still the diff can be seen from the naked eye, that can't escape.

    This is what I do on my bike with a 50mm front rim and a 26X4 Husker Du on front and a 29 inch 2.4 tire on the rear. In my case, one spacer makes up enough difference. I've never measured the circumference difference between wheels, but it's totally noticeable to the naked eye, so I'd guess it's a fair difference. I'm on a Jones. I would gladly try and stuff a 29+ back there if I could. Depending upon the geo of this new Jones, I may just find out.

    Oh, and there's always the new 27.5 fat wheels and tires that are sure to come down the road. In fact, I'm wondering if Vee tires new 27.5x3.25 tire will fit in the back of this new Jones on a 50mm rim. Might pair up real well with a 26 fat front.

    Slow Danger, seems you have what i have too, my spaceframe has a marge lite with nate tire at the front, with an ardent 2.4 on a rabbit hole back at the rear...

    Guess we just have to wait and see what comes out with the Jones plus...
