    Converting my '11 Athem 29er to a 650B?

    In the quest to give my Anthem abit more snap. I was wondering what the results would be running 650B tires front and rear?
    Maybe just having a 650B in the rear would be the be the best?
    Any opinions.
    Thanks

    It will still have long chainstays, but now have a lower bottom bracket too, so more pedal strikes. You'll spend a good bit of coin to find out, and I bet it will be a minimal improvement in snap.

    If anything I would try just the back first. I like the bigger front, smaller back on my 650b Ax 26er. My ideal bike would be 29 front, 650b back... but with short CS built for 650b.

    You'd lose about 1" of pedal clearance. The best way to add 'snap' is to go with lighter rims and tires.

    Lighter rims and tires accelerate faster, regardless of diameter because large wheels rotate slower. A smaller wheel with a heavier rim and tire will have less 'snap' although it will steer quicker. 29" forks also have a different offset from 26/27 forks so you could end up in a whole new uncharted territory.

    Thanks for the input. I have a set of Crests and Racing Ralphs on her now. I was just wondering how to make it even quicker.
    I will just need to improve the bikes engine

    Have to agree with the others on this-expense and result may not be worth it. Most of the dedicated 650b bikes are designed around 6" travel AM designs. Check out that forum to get some ideas. Probably better to try and convert a Trance if it's possible.

    Really think the Anthem 29 is a pretty sweet design for many applications. I had my Fox fork "Pushed" to 120 mm and while it didn't make it "quicker" it did make it more responsive and fun. The Anthem can be a fast XC racer or fun trail bike with the right tweaking.
