Compliant (Translated review)
Advertised as exclusively compatible with the fork tubes of Trek Madone frames. This expander is nonetheless compatible with forks from the Emonda series. The installation is simple, the torque is displayed on the inner bolt and the cap bolt. Clean, simple. (Translated review)
Perfect for mounting the steering of my Madone! (Translated review)
