OK, I am going to order up one of the N-Gear today.
I am going to try using a standard take off 46T ring and see how it goes. I would like to use a 44T, but since my intention is to use this on fast road training rides, I am not sure it will be enough even with an 11.
We'll see how the chain stays on with this setup and if the gear ratio is enough.
I like the rocket ring concept and they are cheap enough to try out. I will also try to find a beat up chainring that is big enough so I can grind it off to use as a guard. Will a 2T increase be enough. For example, if I run a 46T, will a 48T ring ground off provide enough height to hold it on or do I need to find a 50T, which will be more scarce?
Thanks, I will report back with a pic of progress next week.
