That’s one of the Hotspur tubes before it was fabricated last week. It’s being built up this weekend, with a hotspurian theme, and readied for the Handmade Bicycle Show on 2/8.
More details are coming and, as an aside, before naming the bike, I consulted the Naming the Bicycle section of the Bike Cult Book. I didn’t crowdsource the name though, as Merlin Mann jokes about in this 5ives post.
