    Smile Geared to SS conversion

    Singlespeed gurus,

    2010 Bontrager RXL 29er rear wheel geared. What do I need, really? I have mixed suggestions from LBS and riders about conversion sets.

    Frame=2012 Niner One 9 ordered and XTR 970 32t front.

    Any pictures(bling) will be well appreciated.


    Thanks,
    Al

    Spacers and a cog.

    There is a FAQ sticky.

    He's ordered a One 9. No tensioner necessary. And that conversion kit comes with garbage stamped cogs, which I wouldn't recommend.

    1-1/4" PVC pipe, to make spacers, and a cassette to cannibalize until you find the right gearing i.e. 32x18, 32x16. You can also use some of the spacers in the cassette to adjust alignment.

    PoisonDartFrog---singleator and chain guides. I just want to be sure that Niner frame and its ebb 2 is all I need so I don't have to deal with chainlines when switching the geared hub to SS. Any thoughts?

    I'm ready for the beating with the carbon fork. They say I have to loosen up on bumps and downhills.

    They are right. You'll have a fairly steep learning curve. The plus side is that it will climb that much better and that'll mean you'll persist with the downhill technique until you get it right. Get a big cushy front tyre.

    FWIW, the Niner is single speed ready. Follow the instructions for the EBB. You'll need nothing else to add that will affect your chainline. Just measure the chainline properly. Half the width of the seat tube, add that to the distance from seat tube to chainring. That's your chainline to work with. Take that figure and subtract it from 67.5. Take the result and (with the rear wheel off) measure from where the inside of the dropout contacts the axle. Use a ruler or other straight object placed flush against the axle face to assist in getting the measurement accurate with the height of the rear sprocket.
    I see hills.

    I want to climb them.

    Update: Niner air 9 carbon and Gearclamp conversion kit. No spacers needed. I'm not sure if a non tapered Niner fork will look seamless.
