I didn't realise until yesterday that Laid-Back's Paper Bicycle has just the same front hub as I am considering - SA dynamo/drum.
I took it for a spin yesterday and couldn't tell whether the dynamo was on or off except by holding my hand in front of the light. I'm rather a sensitive soul so this was a pleasing revelation.
What's more, the braking was fine too (many people on the internet suggest that drum brakes are a bit shabby). Very different feel from my discs, but in no way inadequate... even better once broken in apparently.
I dropped the frame in at the Bicycle Works just now, agreeing that it ought really to be properly faced rather than done by me in the communal stairs with sandpaper (as I've been assured that this, my first steel bike, has a lifespan of around 20,000 years if I don't get it wrong...)
The headset I got from On-One is pretty, well, "distinctive" would be a kind term I suppose. It promises to outlast the cockroaches, so I thought it might be a good choice... but I didn't realise until it got here that the lower race, as well as having complicatedly invincible sealing, also runs on oversize bearings.
I'll post a pic when I get it back from the shop on Tuesday, and you'll see what I mean...
