1-1/8" stem too small for 1-1/8" steerer--huh?

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.

Thanks.

Sounds to me like they sent you a mispackaged item by mistake; get with them and let them help you out.

It happens.

Some info that may help: http://www.sheldonbrown.com/gloss_st-z.html#stem
Scroll down to Headset Sizing: http://www.sheldonbrown.com/gloss_ha-i.html

Your not providing enough information to determine what the issue is.

-What is your current setup. Do you have a quill stem. What is the outside diameter of that?

So?

You do realize that a quill stem for a 1 1/8" steerer measures 1".

I e-mailed BBB this afternoon. No response, but I'll keep after them. That said, the stem is pretty unique for BBB. It's adjustable and accommodates a 31.8mm OS handlebar--that eliminates their other products, at least according to their Web site.

I read the Sheldon Brown articles and did other research beforehand, so I'm surprised that I did not foresee this issue, whatever it might be.

The bike is a Giant Cypress with a 22.2mm Zoom adjustable quill. Hence the Nashbar threadless stem adaptor, which fits beautifully. Its lower section is 22.2 and the upper few inches is 28.6.

I was under the impression from the Nashbar Web site that the adaptor was intended to let bikes with 22.2mm threaded steerers use the newer 28.6 stems.

Although truth be told, Nashbar does not specify that it's intended for 28.6 stems in its description--they just say it will let you take advantage of "the great variety of new stems," or something like that.

Conestoga, as already mentioned above the stem is just mis-labeled or mis-packaged. Phone or email Nashbar and tell them of the mixup and i'm sure the correct item will be on it's way to you in short order.

You cannnot use a quill stem with that adapter. It is intended to let you convert a 1" (22.2mm ID) threaded steerer to use 1-1/8" (28.6 mm OD") THREADLESS stems.

Hillrider is correct, as usual. He's obviously a real bicycle mechanic and he can read.
