The CWP - 7 is an all - purpose tool designed to effortlessly remove both square taper and splined crank arms from 3 - piece bicycle crank systems. Its swappable rotating tip gently and firmly presses the crank arm away from the bottom bracket spindle. With extra - fine threads, it offers the necessary leverage to take out even the most stubborn cranks. An adjustable wrench is required for using this tool. This tool is made for the 22 x 1mm threading in the most common square tapered cranks, but won't fit older style French cranks with larger openings. It has rotating tips (11.3mm and 16.3mm) at each end to remove both square and splined crank arms.
Using the CWP - 7 is quite straightforward. First, make sure you have an adjustable wrench ready as this tool requires it. If you're dealing with square taper or splined crank arms on a 3 - piece bicycle crank system, choose the appropriate rotating tip (either 11.3mm or 16.3mm) depending on your crank type. Then, place the tool on the crank arm and use the adjustable wrench to turn it. The extra - fine threads will give you the leverage to remove the crank. Just keep in mind that this tool is designed for the 22 x 1mm threading in common square tapered cranks, so it won't work on older style French cranks with larger openings. For maintenance, after each use, wipe the tool clean to prevent dirt and grime from building up. You can also apply a little bit of lubricant to the threads to keep them working smoothly. Store it in a dry place to avoid rusting.
