For use on Xtracycle brand EdgeRunners model year 2014 and newer. It requires a braze-on under the down tube. Wondering if this stabilizer can be used on your Xtracycle? Shoot us a message at firstname.lastname@example.org on on Live Chat (bottom right corner of the website) and we'll be happy to help you! For other bikes, Hebie makes some good clamp-on options.
