help identify a quill stem

Please take a look, what brand and which bike uses this type of stem. May be for a odd shape handlebar.



Thanks

I feel like I've seen one back in the 80s, but couldn't name it. The bar is probably round, just with a side-tightening bolt.

First, you really can't ID bike from the stem. First, SR was used by many manufacturers. Secondly, one of the easiest parts to swap out is a stem, and its a common change. People change out stems for personal fit, handlebars too. Never assume parts on a bike are original unless you bought the bike new. Even then, on a bike that may be 35 or 40 years old, would the original owner remember every single change made?

Most of my bikes do not have original stem. I can only think of one out of a dozen bikes or more.

Was curious as to which bike models may use this as a factory part. The design looks like it may be prone to creaking. Interesting design nevertheless.

My leading candidate would be a 1985 Nishiki Tri-A. The frames came in that pink colour and had internal rear brake cable routing. The headset was Shimano New 600EX, as shown on the subject bicycle. They used that stem. The OEM cable housing and handlbar wrap was yellow, to match the logo. Here are a couple of pictures of one but with replacemement cable housing and handlebar wrap. Yes, I know it's non-drive side, but that shows the rear brake cable port to better effect.

Technically, the stem is not an SR Aero, as described on Velobase. In that case, "aero" is more of a generic description. The actual model name is Custom-R, often abbreviated as CR.
