a closeup of your drive sprocket
Just showing off some of our new grade 8 hardware… ya so what if it is overkill 
Don’t forget the COTS bronze bushing, shaft collar, and hex bolt/nut combo :rolleyes:
*that’s where you’re wrong
pretty sure this wouldn’t fall under the category of COTS*
nope i was wrong you’re correct definitely a COTS, i can never remember what it stands for.
Looks like a VEX collar to me
nope regular 1/2 inch collar
those are grade 8 hex bolts
our wheel is in the left of the picture
with a pressed in steel sprocket and a brass bushing to keep it all spinning well.
