State Bicycle Company CNC machined track crank. 48t chainring, square taper interface, 170mm crankarms, comes with a 16t cog that fits a fix/free hub (does not include a lockring or freehub). Comes with a 103mm sealed bearing.
I took these off a bike I bought new a few years ago. They were only used for a few test rides then stored. They're in excellent condition and ready to go.
Contact using "reply." Plan to meet me in the Glassford Hill shopping area to purchase. Cash only, no apps, no rigmarole, greatly appreciated.
