The first step in setting your saddle height is to find an estimated base height to start things off. Ideally, when it comes to saddle height, it is recommended to start off with the saddle at the height of your hip bone. To do this, loosen the seat clamp with an Allen key (or the quick release lever, if your bicycle has one) and raise your saddle to the height of your hip bone, roughly. You can stand by the side of the bicycle to know when to stop and tighten the seat clamp. However, make sure the saddle is straight before you tighten the seat clamp.
