How to adjust a Bushnell eccentric bottom bracket

Custom occasionally ask how to adjust their tandem timing chain with the Bushnell eccentric. This is a short video I made to show them how to do that.

I just re-tightened my chain. This system is so clever!!

With the previous eccentric, it took me an hour and a half.

This is super helpful. Thanks so much.

That little tip you suggested at 1:40 was just what I needed! Been trying to figure out how to solve this problem for quite a while. Thanks

This 3 min video save me a bunch of time, frustration, and money. I applied the same concepts to a belt driven bike with internal hub gears and an eccentric bb. Thanks so much!

Thank you - great for loosening off my tandem so I could correct the pedal sync.

is there a torque setting on the 4mm? Mine seems to keep on slipping. Also - when timing chain is replaced: is there a "home" place for the eccentric shells (to permit later chain adjustment). We like to ride "in phase". Does one just "eyeball" the crank phase? Or is there a super cool secret way?

Post some bikes! Outlaw, Phinney Ridge etc.
