I put a set of triple trees on my bike and wanted bumpers to keep them from banging on the frame. Found some on ebay but they were expensive so I scrounged around the hardware store to find something that would work. Ended up with these rubber leg tips that are made for 1 1/8" to 1 1/4" legs. My tubes are 1 1/4" so they are a tight fit. Just cut the bottom of them off and sprayed some WD40 on them to install.
