I'm pretty sure Jan Heine PhD. at Rene Herse Ccyles isn't stupid. He's carrying on the tradition of handmade lightweight touring bicycles Rene Herse was known for. He also runs these things himslef in actual bike races. Paris Brest Paris, and Outbound XL. Probably not too many hipsters in that group. I doubt if he expects to sell more than a dozen of these, if that. There may not be more than a dozen people who can actually install one.
I think of it as art as much as anything.
If the fornt derraileeur has you confused,you should see the rear mech that goes with it.
