I find 32:15 gives me the best chain tension (as i don't have horizontal dropouts and don't want to run any kind of chain tensioner). People usually recommend 2:1 for off road or if particularly steep 32:17 or 32:18. On the road however you can go reasonably upto around 48:16 but this is hard work in hilly areas. I would recommend anyone to try it, it is great having a bike that makes no noises and has no flex or skip in drive, it also seems good for fitness because you just get on with it and pedal rather than make things easy for yourself.
