Thank you! Mosaic bought Spectrum, I remember speaking to them at NAHBS a few years ago. Alchemy does their own paint inhouse but I went with minimal anodized logos: downtube/headtube/seattube. Their ti quality in on par with Mosaic, though recently I discovered Sturdy Cycles and Prova Cycles with their 3d printed parts and am drooling a bit.
Regarding my drivetrain, I run a 3T Bailout 9-32t cassette with a 42t front ring which gives me the equivalent of 52/36 11/28. The Bailout cassette has 1t jumps from 9-13t where it matters most and bigger jumps higher up. I have gearing to climb and sprint still and after over a year I don't see myself going back to 2x. 1x will only get better with time as options develop from SRAM and new DA coming
