I like the idea. On motorcycles one of the problems with belts is the super power aftermarket motors that are being developed for harleys. These have proven to be belt breakers, and are somewhat responsible for the return of chains. Of course the cool thing about bike chains is that they are lifetime oiled and sealed, which doesn't seem to a bike miniturizable concept yet. But I guess the issue would be whether on this scale there are any similar problems 250 pounds guy tearing into a hill with 100 pounds of gear, "snap"? I doubt it if it is designed for mountain bikes.

The only part that looks open to tragedy with this system is the belt itself, and that would be light and easy to carry and replace on the road, so it would be a mater of whether it's a once in a lifetime problem or an every 50 miles problem that the belt gets cut with a stone chip. I have enough excitement of that type with tires.

Efficiency is my main concern. Something that lightens the rotating load on a Rohloff would b a great pitch against the already easier running deraileur system.

Then there is the cost, it can't be cheap? There is also the belt length, how many options is it a delco item or only in a few places on earth. I'm betting on MSC.

Sure looks better than that lifetime lubricated chain in a chaingard option.


The break in the chainstay is going to take a litte thinking over....
