Gates belt drive - ShimanoSG-700Alfine compatibility?

Postby polydexta » Fri Jan 25, 2013 11:28 am

Does anyone know if a Gates belt drive setup can be used to drive the Shimano Alfine 700 or the Rohloff 14 speed?

Thanks

Some discussion from the Thorn Forum about this, and more specifically a response from a manufacturer. It seems that with a Rohloff, to retain their very valuable worldwide warranty, you'd need the conversion to be done by Rohloff and using a frame that would meet their specs for rigidity.

Probably cheaper and easier to get a bike that is already designed for it. There are such, but most are sold out of Europe and will cost $$$$.

Retrofitting to the Alfine 11 I know little about, but it may be an easier task :?

Fitting a belt drive to an Alfine 8 or 11 is reported to be fairly straight forward.

A Di2 (electronic shifting) Alfine is much more problematic, although apparently it is possible, at least if you have access to a machine shop.

Agree with il padrone, working with a frame designed for a carbon drive will save time and money.

Hi polydexta,
This company seems to have some clues on installation.

Yes straight fit, 3 spline, fits on as you would with a normal chained sprocket.

St Kilda Cycles built my touring bike up with a Rohloff and Gates Belt Drive. It's a modified Charge Duster. I love it. I'd get the Center Trak if I were doing it again, but the extra 2mm width of the belt might cause problems on a modified frame.
