Belting!

Not sure I'd be convinced until I had a chance to try it out for myself, the only thing is that if you wished to switch to a 17t/18t down to a 15t for example it's not as simple as moving it further back in the drop outs .

What the fuck are you talking about? Of course you could move your wheel back.
Average chain length must be somewhere around 100 links so that'd make 200 moving joints. Add the bottom bracket, pedals, hubs, freewheel, headset and 2 brakes and levers and you have 211 moving parts on a s/s freewheel bike. Now consider that by replacing the chain with a belt you would go from 211 moving points of wear to 11.
Thats almost a 95% reduction in the moving, wearing parts on a bicycle.
Sounds pretty revolutionary to me.
