The Knuckle Saver Pedal Wrench Adaptor solves the heinous problem of removing stubborn hex-mounted pedal spindles, and is available in 6 and 8 mm versions. Combine this tool with a pedal wrench to easily and safely remove or install. Position your hands for maximum leverage while ensuring they don’t impact anything but air when it breaks loose. The knurled surface helps you spin it on and off. Our Knuckle Savers work with any pedal wrench. This tool is also helpful with tight 8mm crank anchor bolts, especially self-extracting ones. Ergonomics are incalculably better than a naked hex wrench. Your tendons, joints and knuckles will thank you!
