Quick Summary
The Oumers Bicycle Crank Extractor Puller is a bike crank removal tool for square threaded taper cranksets. It is described as a crank extractor for removing square type crank arms, and it is not suitable for octalink cranksets.
What to Compare Before Buying
- Crank type: This tool is for square type crank arms and square threaded taper cranksets. Check the crank type on the bike before choosing it.
- Bottom bracket fit: The product text says it fits any brand type bottom bracket. Confirm the crank and bottom bracket arrangement on the bike matches the tool’s stated use.
- Tool construction: It is described as having forge steel construction with a plastic hand grip. If handle feel or material matters to you, compare that against the other tools you are considering.
- Compatibility limit: It does not fit octalink cranksets, so this is not the right option for that style.
Before You Decide
Check that your bike uses a square type crank arm or square threaded taper crankset before choosing this tool. It is also worth confirming that you do not need a crank extractor for an octalink system, as this tool is stated not to fit that type.
