Framebuilders - Builders of Custom tour bike w/ Belt, Rohloff, lugged steel?

Which builders have made a lugged steel touring bike, with Rohloff Speedhub and the Gates Carbon belt drive? There are several builders that have experience with belt+Rohloff (i.e. Co-Motion Americano, Vittorio), but they are welded frames. Please post the builders name if you can think of any. Thanks.

How do you feel about oversize tubing and sloping top tubes?

Sounds like a small segment to say the least. Gates still tells me that Rohloff is working up the parts for their hub, let alone how it will all go together on a lugged bike, so you are looking for folks who are machining their own solutions.

What is your main concern? The only weird thing about Rohloff and Gates is the split rear stay, or drop. With Rohloff itself you get into building rear ends that can take the loads of their gearhub. The Rohloff torques the left side and the gates is on the right. So you might be able to get a fairly standard looking right side chainstay arrangement with an S&S coupling in there? But even if you can't the rear in is basically brazed anyway, so you can have whatever you want.

Is this a tech question or are you shopping for builders?

I am shopping for a builder. There are several builders already making bikes with Gates CD belt and Rohloff, but none (that I am aware of) which are lugged steel and this. I simply like the look of lugged more than welded.

Part of that is due to the combo- percentage wise there are not a lot of Rohloff bikes out there, now a lot of Gates drive bikes, and defiantly not a lot of both.

There just aren't a lot of customers asking for a lugged, belted Rohloffed bike- so there are not many in builders portfolios. I have experience with all three, but not all three on the same bike (because no one has ordered that combo from me yet). Look for guys that build the type of bikes you like and discuss the parts integration that works for you.

The Gates part is simple, you just have to put a split in the rear triangle somewhere. If you find someone that builds lugged touring bikes that you like, and has done a Rohloff bike, there is zero learning curve to put them together.

I think for a touring bike I would be inclined to use S&S couplers for the rear triangle split. Paragon has a coupler now that seems like it would work well too.

I would be willing to bet that Bilenky would be happy to build you such a beast.

PeterPan1 makes a good point about the availability of parts. And I would add that it's probably best to have the parts on hand before proceeding with a design.

Are the parts available yet, anyone know? The Gates parts are pretty limited as far as getting the right ratio for a touring bike is concerned, and the Rohloff parts to be will presumably be limited to their "legal" ratio, which are at the margin of what some want for a touring bike. No problem with a chain because the chain parts are all over the place and one can do what one wants. Every time I ask about the parts I get told they are coming shortly. Meanwhile there are bikes out there like the Co-motion. Of course they have the CNC capability to make it happen I guess. Or the buying power.

Just a thought here - there are motorcycles built with a single chainstay, and there is the funky cannondale 'lefty' front fork (and Obree's single blade fork), would it be possible to design a frame with a single, left chainstay, that held the Rohloff hub, and left the drive side completely open, making it agnostic when it came to belt vs chain drive?

That may be possible in a carbon build but I think a breakaway seat stay is probably the only route in a traditional lugged frame.
