Stem size in a Nishiki Riviera mixte?
Dear All,
I need to swap out the bars and stem for this Nishiki Riviera I’m building for my wife. She wants upright.
BUT, what is the stem size for this bike? How do I determine, minus any tools or LBS willing to help?
Is this a “standard” size? Thank you.

I would assume that it is a 25.4 mm clamp diameter due to the build and apparent era of the bike. However, if you have a set of calipers (a useful tool when working on bicycles), you could verify this easily. In place of this, you could try peel back the foam grips at either of the ends of the bars, sometimes the clamp size as well as other specifications is stamped there. Finally, in a pinch and sacrificing accuracy, you can clamp a c-clamp gently to the bars directly by the stem and slide it of to be measured using a ruler.
Cheers

The stem quill is 22.2mm in diameter, often referred to as a 1" quilled stem. It's a very common size for older bikes.
By the way, you'll need some different brake levers, brake cables, and grips as well if you're going to a flat bar.

Thanks very much. I should have helped by saying this is a 1984 bike.
I think I'll go with the guestimate. I don't want to destroy the foam padding, which is why I'm swapping out the stem to get new bars on.
I guess I'll try to buy the stem and bars from the same source to be sure they fit. I know my own bikes, but this is an exotic to me.
Thank you, again!

It's a very pretty bike.
Going to more upright bars you have a lot of options including a flat mtb type bar or, perhaps, north style bars which were common on English roadsters, like the Sports and Superbe. For a really cool bar treatment in an "upright" style, check out the recent thread about the Polyvalent build. Very nice bars.
edit: I just looked at the Polyvalent thread -- they're VO porteur bars.

While not as cheap, the bars used on the Electra mixte are very nice. I'll probably go with VO, but just for the look, see:https://www.electrabike.com/store/
Choose the Ticino Parts Collection to see the better bars. You can look at their built-up bikes, too.
