Single speed crank question

[irb_2]

What is a good crank to use for setting up a 1x9 cross bike with? Im looking for something with 32t ring because I have a close gear ratio in the back(12x23). Any information would be a great help

Thanks

I'd say 32T is way to small. You'll need at least 36.
Go for a 38 and you can use any standard BCD130.
That will give you a 10-25mph speed interval. (cadence 81-95)
