Belt drives are ace. simple as that. I love mine.

Just because
Thats why I did it. The silence is outstanding.
Do Belt drives take mush setting up? Is it straight forward enough to tension the belt?
Mine did, because the suspension linkages give a little too much play. but new dropouts solved it (search my history). Gates centre-track system would have helped too.
Tensioning is as per a normal tensionging system, but you do need lots, although not so much you have to re-tension every time you remove the wheel. From my experience of chain-drive bikes with EBBs, I wouldn't trust them. Track-ends with tugnuts, or sliding dropouts are the better way to do it.
