Easy Knees Pedal Shortener
|Delivery time:||Available now|
Many bikes and trikes are equipped from the factory with 170mm or 175mm cranks. These are great for the long-legged or those of us with super human kneecaps, but for most people, they are just too long. Easy Knees Crank shorteners allow you to effectively shorten your crank arm length and experiment to find out how much shorter works for you. Crank shorteners can also be used to accomodate legs of different lengths.
If your legs are the same length, but maybe your knees aren't as good as they used to be, a shorter crank arm can help alleviate some of the strain.
These crank shorteners are designed for use by adults and for use with modern cranks with curvy, shaped arms. The unique design of the side anchors makes them both very strong and able to handle any crank size and shape, even really wide or really curved ones. The side anchors that lock to the crank are super heavy duty to handle adult pedaling loads and have a very wide (22 to 44mm) adjustment range. The adjustment is both simple and very positive. This feature is what drove us to make crank shorteners. No other crank shortener can handle the range of crankarms or pedalling forces that these can.
If you have one bad knee or have limited range of motion in just one leg, check out the Easy Knees Pedal Swing. It is designed to help you find the right pedal stroke for each leg instead of compromising on a single adjustment that doesn't truly fit either leg. With a pedal swing, even though both legs are the same length, they can each have different range of motion.
