The Monkey Lab
Having a frame that perfectly fits your riding style and body type can make the difference between a bike that motivates you to get out and ride often and one that sits in the corner gathering dust. Changing a half a degree on a tube angle or a quarter inch of a tube length can completely alter how a bike rides and feels. (This might be too bold of a statement. Run this by Carmen and Tyler and see what they think. I am more inclined to say something like "relatively small changes in ........ can make a noticeable difference in how a bike rides and feels".
