Bacciagalupe,
there are actually quite a lot of Fridays with Rohloffs. My Llama has Rohloff specific braze ons, but i don't think i'll install a Rohloff because i didn't like the noise, and the test hub already had 6k miles, so not a big hope of it getting quieter.
I asked BF for a semi-horizontal dropout, but was disappointed that they won't do them, even on customer request. They said I'd want a tensioner anyways, so the chain doesn't flop off every time I do a quick fold. True, but i'd still like the option of going without a tensioner if i want to.
