SOURCE: how do i adjust the height of my handle bars on my

Modern threadless headsets require height choices to be made at build time because once cut, the steere can not be made longer. Many bikes come with a medium height stem and a few spacers underneath it to allow for lowering it. All threadless stems can be flipped over to change tthe rise angle and you may find a solution in that. Or you could gog to a Local Bike Shop and have them advise you on replacement stems with diffrent rises and reaches. The extra spacers, if any, can be placed above the stem untill you're satisfied with the fit. Then you can cut the excess off and save the spacers or leave it as is, but it looks dorky..

Unless you understand threadless stems, you should not attempt to change anything as your life depends on correct tightness. Look here:

Serial Numbers are usually in one of two locations.

1. Turn the bike upside down and look at what is the very bottom of the frame where the pedals and cranks pass through. This is the bottom bracket shell. Serial numbers are commonly stamped here and will be a long series of numbers and letters
2. Occasionally they are also stamped inside the rear dropout on the left or right. The rear dropout is the part of the frame where the rear wheel is connected.
