    I really hope Pivot releases a bike similar to the Mach 429C but with 650B!!

    I really hope that Pivot releases a bike that is similar to the mach 429C but with the 650B wheelsize. I rode with my buddy who just built up a Mach 429C but he is 6'2". I have a 29er HT and don't really like the 29 wheel size. I also own a FS 650B and love the wheel size. So am just hoping aloud that Pivot releases a 4" travel 650B FS bike. One can hope.

    Me too! At 5'8" I'm just short enough that 29ers are a little too big (as I'm not a cross country racing type).

    The Firebird is sort of compromise. Like it or not 650B wheels are here to stay. Pivot don't rush things like the carbon production. Relatively small bike company must be ahead of the curve and in the case of 650B, Pivot lag other company.

    I saw a guy with a mach 5.7c 27.5, Im not sure what his name was, I think Denny? He seemed to be impressed with it. I tried to get a photo because it looked good, but they are blurry.

    Question: what would you think of a 429c built out with 650b wheels on high profile tires (feel free to name them), and the new Talas 34 29 (140/110). The 140 should compensate a bit for the loss in HA and BBH when you need it most. Or would the 27.5 34 Talas 27.5 be a better idea, for some reason? Sub in 170mm cranks for clearance (long legs need not apply). Would this be a totally wonky build? I can't sit around and wait for Pivot to build it. My wife says "go" now, who knows about tomorrow. Just thinkin' out loud. TIA

    Have you ridden the 429c? I thought I wanted a 27.5 as well (I'm 5'8), but the 429c sure doesn't feel like a 29er, until it comes time to roll over something. Very nimble.

    Yes.

    Also, changing both wheels to 650b will not affect the head angle, and the BB will be too low regardless of whatever else you do to compensate. You're taking a bike with an already low BB, and lowering it more than .75", regardless of what tires you run.

    I agree with panchosdad. I switched from a 650b to the 429c. Best move I could've made. The 429c flat out rips.

    Am I the only one waiting for a 29er with a 160mm of suspension? Seems like a no brainer but I guess I'm in the minority.

    Ok that helps. I am a little shorter at 5' 6" but the 429c should be ok for my height.

    429c is a quiver killer

    I would say yes you are in the minority. Would be about 35 pounds with 18 inch chainstays wouldn't it? A mate bought a Stumpy 29er and isn't happy with it. If he was 6 foot 2 he might have been OK but he thought it was too much bike for him. Good on rocky climbs but cumbersome on tight or twisty singletrack. He had a 4 inch 26er previously so you can imagine the difference.

    Not really. Specialized Enduro 29 has 155mm of travel, 16.9" chainstays, and...

    My Firebird is already 35 lbs so this is not a deal breaker for me. The Stumpy is a very capable bike, but it would be really different for someone coming from a 4" 26er. Give him a year and see how he feels about 9ers after that.

    My girlfriend is 5'6ish and shreds hard on the 429c. I hope Pivot makes a 130mm 29er and run a 150 up front. Would be the best bike ever.
    I like to ride bikes fast.

    Certainly not equally equipped.

    XX1, carbon rims, Kashima Fox & CCDBA on a Pivot frame is probably right at $5K - at wholesale cost.

    I'd jump on a mach 4" 650b bike in heart beat.
    Had a 429, did the trans Rockies on it - I was quite competitive. Amazing suspension, like nothing I've ridden but the thing was just too long. I'm 6'3" , 225lbs and have had a load of 29ers. I live in the Rockies where we have steep, technical, long single track climbs followed by the same descents. Nothing compares on this terrain to 650b, no matter how tall or short you are.
    I've done many western Canada stage races and big one day events and the only time I've ever won was on a 650b hardtail on a technical course in the rockies. My other bike is a converted Rocky Mountain element which is amazing (I'd like a lower BB).
    Pivot could sell a ton of these bikes as the perfect stage race bike but alas my money's on Santa Cruz to get one out first. Hope pivot proves me wrong
