What's the deal with layback seatposts. Moots has them on every bike on their website. They clearly look more aggressive. I'm running a straight seatpost on a Vamoots that was fitted to me, but is a stock frame size. Would it be stupid to put a Moots layback seatpost on instead of a straight one. Some of the layback distance could be made up my adjusting the rails. I tend to find myself at the back of my saddle a lot anyways, so I'm thinking this may be a good setup anyway. Thoughts? My seatpost only sticks out of the frame about 4 inches so I don't even know if that is enough to use a layback.
