Non-clutched is a winner. A few years ago I set up a Chromag Aperture as a 2x1. Using a Zee short cage/DH mech with no cable to both tension and allow the growth between a 30t and a 36t narrow wide 104 ring (bolted to each other sandwiching the tabs)
The 20t Surly cog out back made for a reasonable, mostly seated climb at 20/30 but with a hand shift at the top I'd have a great charge gear for down or around town at 20-36.
It was an odd solution but allowed for a very versatile big with the fun of SS.
Its fun to craft a franken toy.
