Where to buy a bicycle frame for belt drive with Rohloff Speedhub 500/14

Hey guys,

I would like to assemble myself a bicycle with belt drive (eg. carbondrivesystems or gates) with Rohloff Speedhub 500/14 internal gear hub.

The main problem is where to buy a frame? It needs to be a special frame, with an opening possibility to fit in the belt, as well have a good fit for Speedhub with the rear cog.

I would greatly appreciate if you could share your experience who sells these frames with shipment to Australia Sad ...

Cheers

It looks like it is a mountain bike spaced hub and is made for rim brakes or disc brakes. Some hybrids are 135 spaced as well.The big key is the rear dropouts need to be slide mount not vertical, so there are a couple of the Surly frames that look like they would work and I like the Karate Monkey buy surly will do both 26" or 29r. I know specialized has a bike (Rockhopper maybe or P series)with changeable dropouts that could probably be converted. I have only seen 1 of these hubs in person, just last year and the owner had the frame built for this hub but after talking with him I wanted to build one as well. A hill here in town that he rides every day with a 52 22 cog and not in the lowest gear said I needed one of those, still have yet to do this but I will someday.

Hey,
Thanks for reply. I am surprised this frame does not have horizontal (track) dropouts, therefore I have no idea how they tension the belt. Anyway, thanks for the link, but the price seems to be on the high side. I have found Civia Bryant, which goes for around 600 USD.

Horizontal and Track dropouts are different. Horizontal dropouts are the type commonly found on road bikes before aluminum and carbon came along and displaced them with Vertical drops. there is a forward facing slot that the wheel slides in. A Track dropout is a rearward facing slot like the ones found on BMX bikes.

with a multi speed hub regular road horizontal drops are a bit easier to deal with.

The bottom bracket is eccentric. This is the brand I want for an ultimate touring rig, that is assuming they are still being made when I save up enough to buy one. Of course looking at what I put into my C-Dales I could have purchased one by now.

I'm going to suggest if you're already spending the money on a Rohloff hub and a belt drive, just go all out and get a custom frame.

I wonder how many custom builders really know how to make a frame set up for belt drive. I've seen two ways to approach this. One uses unboltable (is that a word?) driveside dropout like theTrek Urban series and the other a high, elevated driveside chainstay so the belt goes under it.

Renovo's construction technique for their commuter and touring frames seems ideal - the dropouts are bolted to the wood.

Rob English's "winter" bike has a separable (I think that's the word) right dropout for a belt and an Alfine 8-speed hub: http://www.englishcycles.com/bikepics/rob/winter.htm . Last I heard he'd ridden this bike through the Oregon winter without maintaining it once.
