    650B Rune

    Doable? Worth it? This whole 650B thing has peaked my interest.

    Think it would be tight in the back. Certainly couldn't run a big tire.

    Based on the Prime, I would think that would be pretty cool if you can get it to work!

    One of the things I like about bigger wheels, is that you're less prone to pinch-flat or burp tubeless tires, due to the shallower angle of attack. So if you had to go from a 2.35 down to like 2.2,I don't think it would be so bad. I've not ridden a 650b so no idea how this applies compared to 29".

    BB height could be an issue. Maybe pick up a cheap 7.5x2.0" shock- that would drop your BB down nearly an inch, and give you 130mm of rear travel, by my calculations... would also slack the bike out a degree or so.

    OTOH.... price of the wheels, tires and shock could go towards a prime frame

    with the short shock, the rear triangle starts bottoming out on the seattube... so i dont think it will work (thought about offset bushes for my damper, but same problem there...)

    Ah, makes sense. I suppose on a coil shock, you could limit the stroke with some rubber washers around the shock shaft. Just to mcguyver it a little further....

    yeah... but why would you ruin a great trailbike just for being "hip" with a 650b full susser?
    take a prime, or stick with 26", thats my opinion...

    Wonder if it would work with my XL frame...would be fun to try. I just need someone local who has one I could try.

    I would like to try a 650B and see if that is the case.

    As far as converting my Rune to 650B I was thinking out loud. Though I do think 6" bikes with slack "AM" geo and bigger wheels does have some merit.

    I totally agree. The biggest problem with 650b is the availability of gear and options.
