might be a good option for some.

I'm looking to use this cog on the standard tensioner arm because it's got a nice long tooth profile.

I like this style of chain retention, let the derailleur pull against something fixed to limit chain bounce. The bearing mounted jockey wheel is more correct IMO than the C-Guide which is just a plastic slider for $35. PLA might be too brittle for long term but maybe I'm wrong. The 3D printable nylon material is way super tough, near indestructible (and harder to print). Support this man.

Ace, gen2 is lighter but I wouldn't say buy a whole new gearbox because of it. If the NeuMotor 3215 compares to the Astro 3220, that could be significant weight savings. Not sure when I'll be able to build the unit for myself, much late work customer work comes first.
