    so how much is "dirt cheap"?
    what size sprockets are offered besides 30 tooth?
    is this something that you made or something that you bought?

    It's something that i made.

    I would have to send the program to a source i have and get it priced.

    My guess would be $20.00 to $25.00 including the spacer plates, sprocket, and disk hub mounting plate.
    Everything you need.

    I can make them in any tooth configuration.
    And each sprocket will bolt up to the same adapter.
    For that price i could probably offer 2 sprockets and the adapter and spacers.

    The setup is made from steel plate and CNC Laser cut.

    what I could use is a 36 tooth sprocket for my Grubee HD axle. I think its a 2.5 center hole with non standard bolt pattern. Can you wipp one of them out for me?

    I can do anything


    Yes i can do whatever you need.
    I will need a sketch or the measurements for the Center Hole Size.
    And i will need to know the measurements for the bolt pattern and hole sizes.

    You could even take the sprocket you have and set it on paper and trace out the pattern for the hole and mounting.

    Just remember the sprocket you get wil be only as good as the measurements you provide.

    Let me know what you think.

    That's Art!

    Great job!

    Can you make a disc brake hub adaptor with a freewheel mechanism-left hand thread?

    I'm doing a front-mounted chain drive, using #25 sprockets. My 54-tooth sprocket bolts directly onto the disc brake hub, but freewheel would be even better!

    The hub with threaded ends on both sides won't work. Both freewheels are right-hand threads, I believe. I have one of Staton's custom hubs with left-hand freewheel for the rear. I need the disc brake freewheel hub for my front wheel.

    Im confused, are you looking for a front hub with disc mount or rear freewheel with threaded (motor side) sprocket mount? A disc mount hub is easy to find, what is it your trying to do?

    My rear Staton hub will accept this sprocket with freewheel:

    Using an 18-tooth jackshaft sprocket gives me 3.611:1 ratio. Hook that up to a 5:1 gearbox, and gear ratio is 18.06:1.

    Up front is a 54-tooth sprocket bolted onto a disc brake hub. Using a 15-tooth sprocket on the jackshaft gives 3.6:1. Hook that up to a 5:1 gearbox gives 18:1 ratio.

    What I'm doing is modifying my Staton/BMP friction drive housings to chain drive. I'm using a 28-speed Giant Rincon mountain bike.

    A freewheel on the front disc brake hub would be the frosting on the cake.:detective:
