Re: A new shift concept for the engineers....
You got it!
The Stainless Steel sprockets I made are for heavy duty bicycle chain...see post #82 in this thread. Like you said, a lot of people use the thinner chain without any problems.
The kit will include a new engine sprocket that has been machined with the correct tooth form.
The CAD graphic at the bottom of post #13 in this thread shows the total thickness of the cluster.
The cluster mounts directly to one of my sprocket adapters. The cluster will be positioned, (on the hub), so that the center sprocket is in-line with the engine.
I just need to make a deraileur and it will be ready to test.
