mod1 or 32 pitch?

[shizzon]

Im looking for a pinion to run on the nue 1515/1y that i have on order, as of right now it has the stock revo spur. will a mod1 pinion work with the stock 32 pitch spur or will I have to get a 5mm 32 pitch pinion, because i havnt seen any. also, if i must use a different spur do you guys have any recommendations? The motor is the tekno nue finned version, wich i hear limits the geraing options a bit, and im looking for 40-45 mph.

Thanks!
