HI,
I've heard that if it is divisible by 9 evenly it should be OK BUT that is ALOT of spokes!....
Maybe it could fit if you removed a few spokes if it is a tight fit?? Just a thought...with that many spokes the wheel should be real strong!....Also, If you can get a disc brake hub to hold that many spokes our sprocket will bolt to the disc brake hub so the number of spokes would be a moot point...
