More low down = less teeth on front or more teeth on rear
Try 17 or 16 on front...

to have final drive to be a lower speed you need to make front sprocket smaller.. increase the ratio of how many times the front has to turn to make the rear turn once
if original is a 18/41 drive or a ratio of 2.278
then a 17/41 will end up 2.412 or a decrease in final speed of about 6%
16/41 = 2.563 or decrease of about 11%
heres a basic spreadsheet calculator I made... LOL

G'day
Do standard sprockets not bolt up to galespeed wheels? How about other aftermarket wheels?

No they dont. You need sprockets specific for GaleSpeed rims.
Not sure about all aftermarket but BST and GaleSpeed have their own pattern.
Has never been an issue for me, I usually get either AFAM or SuperSprox.
