I don't know about you, but I have yet to find a bicycle with a stem that fits my body. Everytime I consider buying or actually buy a new bicycle, I have to have the stem changed. On two of my bikes I've had to bring the bike back to the LBS to have the stem changed more than once. Wouldn't it just be easier for new bikes to come with adjustable stems? that way you could ride around for a while to see what the most comfortable rise and angle were. then, if you wanted a non-adjustable stem, you would at least know the right size to or exchange for.
