to the OP, what is it about the 10t/10t that interests you? That's essentially setting up a 1 to 1 ratio so any torque multiplication happens through your gears only. I would think if you were going through the trouble of something that looks this complicated you'd want more output from it.
well with my theory of a 1x1 ratio there. Feel like the 9 tooth would be too small and the chain may come of maybe frequently. So I believe the 10 tooth sprockets will be slightly less likely to come off. I understand how the gearing works on a traditional two gear bicycle but this jackshaft system has four gears technically 5. The two that I showed in the pictures two more where the chain ring is and the rear cog. If you had a bike that was a simple ss and then you added 8 gears to the rear. Would prefer to uses a smaller or larger chainring? Just curious
