Riding a SS you quickly learn the "secret" it's all about MOMENTUM. You store up as much as you can on descents and the flats to carry you through the hills. As you get more and more fanatical about preserving every joule of kenetic energy, you find yourself blasting through the same corners faster and faster, and programming yourself to stay off the brakes at all costs. To the geared rider it makes you look almost super-human. secondly if you ride a rigid SS (as you should ;-) you learn how to pick better lines and be a smoother rider. You learn to absorb the bumps by letting the bike float over them beneath you rather than relying on your suspension to soak up you sloppy riding.
Most 26" riders use a 32:16, it seems to be the best compromise between grinding up the hills and spinning out ot the flats. Since I am a spinner by nature (out on the road, I can comfotably spin at 90-100 for an hour) My RedLine MonoCog is set up at 32:17 for most riding and I have a 18 wheel for days I'm going to ride hills.
I'm not quite sure how I'm going to gear up my 29" SS when I build it since the larger diameter wheel wil obvioulsy effect the whole scenarion, but I'll likely start at 32:18 and if I find myself spinning out too much on the flats I'll drop it down. All that is moot until On-One releases thier 29" Disc SS frame <holding my breath>
