There's frustratingly little to report at the moment. I ordered Tektro FL750 levers from eBay; they arrived Wednesday. I also ordered Kool Stop Dura 2 brake cartridges/pads, a binder bolt, a seat post, and pedals from a shop in Philly that's on eBay, but the tracking status has been "Shipment Received Acceptance Pending" since the 4th. It's not the first time I've had this experience with this shop, but it will be the last.
I did finally address the headset issue — four missing ball bearings. I've sacrilegiously only added four new bearings instead of replacing all of them. I'll order some this weekend to have that sorted.
Maybe the most exciting news is that I've found someone selling a silver, 32H, 130mm axle, SRF3 wheel locally! I have a front wheel in my storage unit that will act as a stand-in until I decide on a generator hub.
