Riding a bicycle is an increasingly popular activity for recreational as well as practical purposes. However, sometimes it becomes necessary to remove, replace, or clean certain parts of the bike. A track bicycle is a type of bicycle (ridden with a single, often fixed gear) that is popular in urban areas for its simplicity, maneuverability, ease of maintenance and its style. In this article the maintenance and disassembly of such a bicycle will be discussed. For the sake of convenience, this article assumes the bike in question has a fixed gear.
This project is best done in a clean space, with a clean floor, as items with grease tend to pick up dirt and debris. This project can be done by anyone with the required tools, a bit of strength (for certain parts) and an interest in bicycle maintenance. This project may take anywhere from an hour to a day to complete, depending on your level of caution and familiarity with the parts. For the most part, a lot of these steps can be done interchangeably, but removing the parts in the order in which they are listed is one sensible way to go about it.
For example, the seat can be removed at any time; you may choose to leave it on to rest the bike on while it is upside-down while you remove the wheels. A bike repair stand can help hold the bike for many of the steps, but it is not necessary for this project. The pedals are an easy part to remove. Thread: the right crank (chain side) is threaded normally, the left side is threaded backwards. We will remove the left crank arm first, as the right crank arm is connected to the drivetrain and will be removed later.
Thread: the crank puller screws into the crank with normal threads, on both cranks. Remove the dust cap and crank bolt from where the crank connects to the bottom bracket. This usually requires an allen wrench, but may vary depending on your crank brand and type. Once this is removed, there will be exposed threads inside the crank arm, with the bottom bracket spindle visible inside. Unscrew the crank puller slightly, until the “pusher” part of the crank puller is recessed within the threaded part of the tool.
Screw the tool into the crank arm, gently at first. Make sure to screw this tool all the way in, as a great deal of pressure will be exerted on the threads when the cranks are removed. Wind the tool’s handle clockwise, screwing the “pusher” part of the tool back into the bolt that is now threaded into the crank. With some force, the crank will be pulled off of the bottom bracket spindle.
