Bike Bottom Bracket Tools

Tools for bicycle bottom brackets

The bottom bracket is a crucial component of the bicycle, playing a central role in the transmission of power between the pedals and the rear wheel. Like all...

Pedal Keys: simple and robust

Pedal spanners are one of the most common tools used to work on bottom brackets. These spanners are designed to loosen or tighten the pedals, a prerequisite for dismantling the bottom bracket. Generally made from robust steel, they have a thin, flat end that slips easily between the pedal and the crank. Some pedal spanners also feature ergonomic handles to improve comfort and grip during prolonged use.

It's important to note that pedals are often screwed on with considerable force to prevent accidental loosening during use. For this reason, a quality pedal spanner should offer sufficient leverage to apply the necessary force.

Case remover: a specialised tool for experienced cyclists

The bottom bracket remover is a special tool that is essential for removing or installing a bottom bracket. Different bottom bracket models exist, and each standard requires its own adapted bottom bracket remover. For example, a Shimano Hollowtech II bottom bracket will require a splined bottom bracket remover, while a press-fit bottom bracket will need a tool adapted to the bearings built into the frame.

These tools, often made of reinforced metal, must be used with care to avoid distorting the splines of the casing when dismantling or tightening. Case disassemblers are often designed to work in conjunction with a torque spanner, ensuring precise tightening torque and avoiding any mishandling that could affect the life of the case.

Extractors and bowl cleaners: for clean dismantling

Pullers and cups removers are essential when it comes to removing press-fit bearings or bottom bracket cups integrated into the frame. These tools make it possible to remove the components without damaging either the bearings or the bike frame, a delicate operation but one that is necessary for a clean and efficient replacement.

The extractor works by attaching to the inside of the bearing or cup and applying uniform force to remove the part. Cup removers are used to remove the outer cups from threaded bottom brackets. Their precision and robustness prevent damage to the bike's components.

These tools require a certain amount of skill when using them, particularly on carbon frames, where any deformation or scratch can seriously affect the performance and integrity of the frame. A good puller or cup remover is often made of hardened steel, with a design that distributes the force exerted during disassembly evenly.

Bearing presses: perfect assembly

Bearing presses are another essential tool for anyone wishing to install new bearings in a press-fit bottom bracket. This tool allows the bearings to be pressed evenly and precisely into their housings, without the risk of damaging them or misaligning them.

Comprising a threaded rod and discs adapted to the different types of bearing, the bearing press ensures that the bearings are installed with the right pressure and in a perfectly straight position. Incorrect installation of bearings can lead to excessive friction, play in the crankset and even premature wear of the gearbox.

Although this tool is less widely used by enthusiasts than other more basic tools, it is crucial for any mechanic or keen cyclist wishing to ensure that their press-fit bottom bracket works optimally and for a long time.

Other specific tools for the bottom bracket

In addition to the tools mentioned above, there are several other specific tools for working on a bottom bracket and its components. These include the bottom bracket spanner, used to tighten or loosen the screws that hold the bottom bracket in place, and the chainring spanner, used to work on the screws that attach the chainrings to the cranks. These tools ensure precise adjustment and secure power transmission.

The motor sprocket tool is another specific part, useful for electric-assist bikes. It allows you to work on the transmission pinion of the electric motor, which is often more difficult to access than on a conventional bike.

The crank clamp is used to adjust or hold the cranks in their correct position. Some models even include a tap to restore or adjust damaged threads in the cranks or frame. Finally, the crank extraction screw is a practical tool for removing cranks without risking damage to the crankset axle.
