Introduction
This guide shows how to remove and replace a saddle on a bicycle. The steps include removing the current saddle, lubricating the bolts and rails, reinstalling the new saddle, and securing the saddle's connection to the frame.
The bike seat used in this guide is a Trek Fx2, a hybrid bike meant for fitness and commuting, although the instructions apply to many other bike saddles, whether they have two bolt or one bolt configurations. If you are unfamiliar with this process, we recommend taking some pictures of the different angles of your seat placement before starting so that you know what configuration to set it back to.
This process can be helpful when your bike saddle is damaged or if the seat is improperly set on the bike. With such replacement, you can continue to use your bike for its intended purpose.
