Quicker Rear Sprocket changes

Maintenance, Repair, Equipment & Tools

I use these in practice sessions when experimenting for the right gear ratios…I bolt them in properly for Qualy, heats and races through. 1 thin stainless 6mm washer on the ball side makes for perfect length for my setup of 219 gears, sprocket and chain guard. I remove the little bail handle. I am a rookie this year but between the Odenthal sliding mount, split gear and these quick-releases I can change a gear in under 2 minutes.

So you use those in place of bolts for connecting the sprocket to the hub?

Yes, when I am doing a bunch of gear changes dialing in a new track I use those through the gear, guard and carrier with a hardened washer.
