Works great

Stock cranks in the U.S. are typically 170 or 175mm long, which is too long for people with inseams less than 33.5-34.5in. I was experiencing knee, hip and lower back pain. I’d read a good place to start is 20% of your inseam, so I got this set to suit mine and it has greatly reduced knee and hip pain and eliminated lower back pain from riding. Replacing the original 170mm parts was simple, but keeping the spacers in place while bolting the pieces back together can be difficult as they easily slip out of place. I recommend using a thin layer of grease on the flat faces of the spacers to help hold them in place while you install the bolts.

I ordered Blue it eventually arrived Black. The original delivery was “lost” but nothing was done for a week then the day I could request a refund another item was despatched. Item itself of good quality

I am 5'0" and have short legs. I ride a StreetStrider. These make the stride much less exhausting for me. Easy to replace.

High quality, do exactly what they should, looks good, and a reasonable price. Who could ask for more??

Install was great, BUT non drive side was impossible to remove due to threads being cross threaded. Don’t waste your money, search elsewhere

Great look and fit

Works good and bolts up to a 130BCD but sent it back once because I ordered a 165mm crank arm and they sent 170mm originally and then on the resent arm they sent another 170mm crank arm so I guess I’m just going to stick with this one for a bit.
