I would like you to know that your invention is awesome!
It was easy to fit with good clear instructions.
It worked perfectly first go.
It will now enable me to pull away on my trike on any incline by dropping the ‘front cog’ while stationary.
That used to be a real problem if I pulled up in high gear on the old front derailleur at traffic lights, …with a Mac truck snarling behind me.
Finally it looks so much better than the cog system that looked like a medieval weapon on the front of the trike.
