Rohloff needs a beefy dropout for the OEM attachment. No way an anti-torque bar is getting bolted up to the chain stay.
He wanted a diagatube. I tried to talk him out of it. He reminded me that he's 6'6", and hates having to reach down so far for water. I relent.
Try and find a set of lugs for that middle tube. So I make custom set.
He has a hankering for hellenic stays. He also has a tendency to break seat post binder posts, and asks, "A spare?"
I relent, and come up with a custom seat lug.
Centerpull brake posts, internal fork and downtube wiring, custom front rack and lowriders. 700c wheels with the new 44mm wide Snowqualmie Pass tires. Fenders, of course.
A mad dash the last 3 days to get it done.
Some sanding to do, but that's a wrap.

Amazing, especially for three days + design!
I got a question if you don't mind: When one makes an Hellenic seatstay attachment, does one leave that TT butt at the seat tube long enough to link in the seatstays where the TT has more meat and greater strength? Seems to me nearly all the rider mass plus the shock load from rear wheel road shocks is going right into that poor little 0.4 mm tube section (depending on the tubeset and alloy of course). We know darn well these deigns have been done and with success, so I'm not suggesting it isn't feasible. But how is it normally done, or in your opinion, how should it be done??
The visible geometry certainly suggests the short length of TT opens up another degree of flex freedom compared to the grand conjunction of TT, ST, and seatstays. But it it really more flexy?
