    Gates Beltring (39 tooth) + XTR 970 fit problems = Anyone use XT?

    Just ran into a snag during a build last night.

    The 39 tooth Gates Carbon Belt Ring would not fit on the my XTR 970 crankarms! The spiders are too tall and won't allow the ring to sit over the spiders.

    I checked the Spot Brand site and noted the 39 tooth SS belt drive Rocker uses a Stylo crankarm....so that is one option.

    Anyone use a Shimano XT 770?

    Yep I am a Shimano guy for life!

    The BCD's are the same...it is the flange on the beltring and the higher spider arms....The pic doesn't do it justice on how close it really is. It is close...but still not grinding.

    Update
    Stylo OCT 1.1 crankset: Works fine
    Spot Brand SS crankset: Works fine

    Right now I am using that Spot Brand Crankset since I can keep the King BB. (No GXP)

    The 39t will fit on the m970 arms. I had to file down the tops of the of the chain ring tabs. It took about 5 mins to slightly file down the tabs. Once you evenly file down the tabs you can get it to fit.

    Here's mine on my Trek Sawyer.

    Thanks for all the posts. And for the record the cranks are NOT for sale.

    It appears a little a little sanding on the tabs will do the trick! Thanks all.
