Working on your bike at home? This two-piece tool set is a must-have for removing cranks and bottom brackets. It includes a crank extractor for square taper crank arms (the most common type) and a bottom bracket remover for standard 20-tooth splined brackets. Both tools are made from tough high-carbon steel, so they’re durable and built to last. The crank extractor is super easy to use – just thread it into the crank arm and turn with a 5/8-inch or 16mm spanner (or an adjustable wrench). The bottom bracket remover works with a 24mm socket, wrench, or adjustable spanner. Together, they let you tackle basic drivetrain maintenance like cleaning, regreasing, or replacing worn parts. The whole set is compact and lightweight (about 250g total), so it’s easy to store in your toolbox or take on rides. Whether you’re a beginner learning bike repair or a seasoned DIYer, these tools save you time and money compared to a shop visit. Just remember: always make sure your bike’s components match the tool specifications before starting. Happy wrenching!
