I bought a compact crankset and external BB, but at the last minute I decided that I like my 50/39 setup, so I’ll store the compact until I’m old enough to need the 34t. Did drivetrain overhaul - new rings, new 12/23 cassette and 3x new KMC chains. I also bought a small slo-cooker and a bag of wax, to try waxing while the chains are new and easy to degrease
