Attention! Producers and vendors appear to change the precise metrics of their axles from time to time! We bought some very good axles from Ali Express in 2022, but they went out of stock. We can not recommend a specific vendor at this time.

If you found a vendor for the axles that work well, please send us an e-mail, so that we can publish the link here.
