Why would that be any more likely than with a chain/chainring?


Like many other drive choices, it has it's pros and cons. If you look at drive systems for camshafts in modern vehicles, you'll see application of both belt and chain driven systems. The service interval on a belt system would be significantly shorter, that's the first thing that comes to mind. This is true in vehicles, and I'd expect the UV / environmental contribution on a bike to exaggerate this.

I didn't know it was in use on MTB setups. How do people like it?
