    Gates Carbon Belt Vs Chain on Alfine

    We're looking to put a Gates belt on an Alfine on a fat bike.
    I've not yet messed with any of the Gates stuff so I have a question.
    How do the rings and cogs on the belt stuff size up to the teeth on chainrings?
    Do I go tooth for tooth or is it a diameter thing?

    Those Gates parts are pricey, so I don't want to buy a ton of them.

    I was thinking 20-30 or 20-28.

    The idea of tooth count / simple math remains.

    Do you ever ride in areas with wet, large grain sand?

    If the answer is no, go ahead and try out a belt configuration. The above condition is the main kind of gunk that the belt doesn't shed well.

    It won't be for me. I'll mention about the sand since we live on Long Island.
    Thanks, I figured the math was the same but having never messed with it before, I wanted to be sure.

    Also, might be useful: Gates&#0174 Carbon Drive&#0153 Bicycle Calculator

    I didn't know they had a 30T front? I thought the lowest chainring tooth count they have available is 39.

    Yeah, that's a little detail I'm not fond of. Wish they could make it work with smaller rings.

    We're building a Pugs with 39-26, Alfine and Marge Lites. I'll let you know how it works. Thanks for the help.
