I have just gotten a Nashbar threadless stem adaptor and a BBB HighSix Adjustable stem. According to Mr. Caliper, the stem adaptor is 1-1/8 inches diameter but the inner diameter for the stem opening is only 1 inch, even though the package says the stem is for "1-1/8 inch fork tubes." Needless to say, I can't them to play nice together. Can someone please tell me what's going on? I'm very frustrated.
