how will it work with derailleur gears? how would one tension it? belts are a lot more expensive then chains, and give less signs of wear before they snap, and it wouldn't work on a track bike.

if they can engineer a less stretchy belt, then why wouldnt it be suitable for a track bike?

Obviously youd have one of the many alternatives to deraileur gears, hub or bb mounted gears innit.

Tensioning could be done the same way as it is now, you could have a sprung tensioner for freewheelers who dont like the hassle of fiddling with the perfect tension. And fixed wheel riders, could just HTFU.
