Hello all!

I have a kona crankset I would like to put on my redline mono cog. My LBS said the crankset was some proprietary bmx set that requires an obsolete bb. Here is a picture of the exact crankset, obviously this picture is not mine as it includes the BB The crank arms have slits for a 10 spline bb. I want to say it is isis but the crank arm grooves are square.
