    my 2009 mt vision 650 conversion

    I bought this frame last year and built it up with some new and old school parts. Just recently I fit up a set of 650b wheels and I'm lovin it. So for anyone wondering 650b fits the rear however it will rub on bottom out. I let all the air out of the shock and the tire rubs at about 47-48 mm out of 50 mm shock stroke so its very little. BB height is just under 13" and didn't noticeably alter standover height. So if you were wondering if it worked the answer is yes.

    CoM looks kind of high, but great clearance. Enjoy!

    I've got about 50 miles on the new setup and its great. Definitely need a dropper post for steep decents and leaning deep into corners but even without one its a screamer. Center of gravity is a lil higher but still very playful, I haven't really had it airborne yet though.the only downer is with a quasi moto tire os hit the seat tube at 104.6 mm of rear travel. So you do lose travel but since it ramps up torward the end I upeed the shock pressure by 13 psi and no bottom outs.

    I did my 2010 with P35 rims 4 years ago. Best $ spent, as I knew it would be some time before I could buy what I wanted. Today it's slim pickins for a 120mm model and they are pricey.
    When 26er riders try my bike, they say that it rips and gives confidence going up or down.

    650b benefits are easily detected on a familiar 26" bike, especially with the quicker geo numbers of the past. Nice and planted, yet still agile.

    I love almost everything about ghe bigger wheels..only two gripes are ots not as playful while in the air and missing that last 15mm of travel. Installing a fox volume reducer and shortening the travel spacer by 4 mm helped drasticly.

    The link is very progressive at the end of the travel. Typical is no one gets to bottoming out.
    I went with a 1/4" shorter shock to both get HA change and lower BB. The shock uses all it's travel now, but it now touches the seat tube. Oh well, mellow trains anyway.
