Bottom bracket tools, bottom bracket wrenches

The bottom bracket is one of the most stressed parts of a bike. Whether you're bothered by an annoying popping sound or need to replace worn bearings, you can't do without a special bottom bracket puller. Since there are dozens of different standards, we offer precisely calibrated bottom bracket wrenches that ensure safe assembly and disassembly without damaging the frame or components.

What types of movers are there?

Choose your tool according to the type of bottom bracket:

Classic squares and ISIS: For older or affordable bikes, there are square-end pullers that are compatible with regular ratchets or open-end wrenches.
External cups: Modern bikes with a hollow axle require a special key for a bottom bracket with teeth (e.g. for Hollowtech or DUB bottom brackets). We offer them in the form of a flat wrench or socket head.
Press-fit bottom brackets: If your bottom bracket is pressed directly into the frame, we offer press kits and knock-out tools for safe removal without the risk of cracking your carbon or aluminium frame.

How do I know which centre puller I need?

First, identify the type of bottom bracket. If your bike has visible cups with external grooves, it's probably a Hollowtech II or similar system. If the axle is hidden in the frame and you only see the internal grooves, you'll need a square drive or ISIS puller.

Is it true that bottom brackets have a reverse thread?

Yes, most bikes with BSA threads (English threads) have a left-handed thread on the right side (the side with the chain). This means that it loosens in a clockwise direction. On the other hand, Italian threads (ITA) have a classic right-handed thread on both sides. Therefore, always check the thread type on the frame before using force.
