I've always loved the look of a bike built with a monostay.
Some great frame builders have made them but for whatever reason they don't seem to be very popular as I don't see them very often (if ever) on my rides.
A monostay frame made of steel from "back in the day" before carbon fiber came along is really what I'm thinking about.
Back then with the different levels/grades of steel tubing and different monostay designs I can only imagine that there could be performance differences, or ride characteristics associated with the monostay as opposed to two seatstays.
Who here owns one and has experience with them?
I would love to see pictures of your monostay bike.

Had a Giant Cadex with monostay and a Schwinn MTB with monostay. There is no performance difference between mono and traditional stays. They look different and that is it. The best monostay treatment I have seen is the old Dekerf frames. Don't know if they are still in production, but how they did them was simply artful.

Yeah, I always thought they were Cool. They seemed so sleek and aero.
My '88 Carbon Ironman has one....but It doesn't seem to make a difference when I'm riding it.
We need pics of monostays.

...oh, MONO-stay. Well, that's very different. Never mind.

Twin Six makes some.

Very clever BobbyG .

Monostay by Pinarello

1998 Dekerf Prodigy.

I have never been a fan of the mono stay myself but if I had to buy one, Rob English makes the ultimate. His philosophy is that the you don't need to overbuild the rear triangle. Check out his bikes on his website.



Here is one that I grabbed from the website. Notice the pencil thin stays, including the mono portion.

Those seatstays scare me.
