Attention serious cyclists and bike mechanics - this BIKEHAND crank arm tool is one of those specialized tools you'll be so glad to have when you need it! Designed specifically for Shimano XTR FC-M970 cranksets, this tool makes removing the non-drive side crank arm much simpler and safer than trying to improvise with other tools. The clever two-sided design features a 4-bolt side for tightening or removing the crank arm cap, and a threaded side that screws on to press against the crank arm bolt, allowing you to pull the crank arm fixing from the spindle without damaging your expensive components. The screwdriver access hole gives you extra leverage to make the job easier, especially with stubborn crank arms that haven't been removed in a while. What's really impressive is the quality - made in Taiwan with precise machining that ensures proper fit and function, this tool gets the job done without marring your crank arm or frame like improper tools can. BIKEHAND stands behind their products with a lifetime warranty, so you know this is a tool that's built to last through years of use. Whether you're performing routine maintenance, upgrading components, or doing repairs, having the right specialized tool makes all the difference in both ease of work and protecting your investment in high-end bike components. This is one of those tools that might not get used every day, but when you need it, you'll be incredibly grateful to have the proper tool for the job rather than struggling with makeshift solutions that could damage your equipment.
