mikeyd 13 Posted July 29, 2019 is there any way to tell the difference between a 1900 205 and a 16mm pin 306 front hub ? Share this post Link to post Share on other sites
Tom Fenton 1,518 Posted July 29, 2019 Usually the 306 hubs have an abs sensor hole/mount but not always. 306 hubs do always (I think) have a tapped hole on the upper surface that the brake hose bracket attaches to. Share this post Link to post Share on other sites
