【MUST HAVE TOOL】: The crank arm puller is an essential tool for any bicycle mechanic and cyclist who wants to save money and perform the maintenance of their bike himself - a necessary tool to remove crank arms and gain access to the bottom bracket that may have loosened causing creaking sounds and/or wobbling. Compatible with most bicycles: Removing a crank set can be tedious and sometimes requires special tools. This crank arm puller is suitable for square taper crank arms and NOT compatible with ISIS or Octalink cranks. Simply use a 15mm wrench and let the crank puller do the job. Robust design: the precise thread of this crank extractor is very stable and does not damage the thread of the crank. It is made of heat-treated, hardened quality steel, which ensures durability and high load capacity. The high-quality (workshop-suitable) thread ensures reliability and long service life. Easy to use and portable: the rubber-coated long handle provides better leverage and a comfortable grip. Using this crank puller tool is easy - all you need is a wrench and the crank puller to remove the crank arm. Thanks to its compact size and light weight, the tool is easy to carry, whether at home or on a bike ride. Professional crank puller tool: Made in Taiwan.
