Leah >From the video: 1. The stem seems to have excessive distance from the bolt to the 'shelf" which stops the nut rotation. The excessive distance allows the nut to rotate when tightened
2 The "shelf" flat appears straight and does not have a rounded out center, as would occur if the bolt was over torqued and caused the nut to 'tear' through the Al body. This needs a close visual exam to verify, the video was not close enough. Whoever installed the original or a later bar may have over-tightened it Clearly, the stem is designed to capture the nut, as others have stated. So your stem appears to have a manufacturing defect or less likely was over torqued and tore thru the Al. You have 2 courses of action, if you ruled out over-tightening via close visual exam: 1. Use the stem, tightening with a wrench and use a star washer underneath to prevent loosening 2. Contact RBW and explain they sold you a defective stem John Hawrylak Woodstown NJ -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
