If you have money burning a hole in your pocket and want to save a few grams, I found this 13-tooth titanium countershaft sprocket on Aliexpress.

For the gearhead who has everything?

40.00 isnt too bad

Yeah, $40 isn't bad for titanium alloy. It might outlast the stock steel sprocket, but I wouldn't buy it for the weight savings alone. Maybe for the cool factor ��

Cool yes, but then that would be something else you'd have to polish.

Or hide it behind this ...
