9 speed question from a noob
 

I have a 2012 Schwinn Slicker (this for reference) and it is a single crank with 9 speed in the back. Frame cracked (long story) so am transferring parts to a new frame.

My question is if I were to replace the crank (which I could not find much info on) would I be able to use any single gear fixie/track crank? So long as it is the same BB style or whatever. I am thinking the answer is obviously yes but i've been wrong before. Also, does it matter the teeth amount? Current crank has 46T and I would have to measure the MM size. Any other issues to be aware of?

Thanks all, any answers/input/etc are super appreciated!

A lot of single speed cranks are for 1/8 chains and 9 speed is 3/32 so make sure you get a 3/32 crank

ok thanks. you are rerring to the chain width i take it?

yes but cranks need to match
