Crooked seat stays

What is up with crooked seat stays?

Just fashion statement?
I think it ruins the beautiful lines of the diamond frame.

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

The theory is that it affords some degree of vertical flex and shock absorption.

If the theory holds, it would make the biggest difference with a Ti frame, though it does seem to help a bit with light steel frames.

If it bothers you, just pass on it.

Yeah, a straight bar is very effective at relaying shock waves, whereas a curved bar can help diffuse shock waves to a degree. As shock waves sent from the axle to the seat post are very much unwelcome, it makes a lot of sense to use curved seat stays (and curved front forks).

A seat shock absorber would offer more based on how much I used one with & without addition to a traditional & modern frame. Personal preference I'd rather have strong frame then a frame that gives way.

Of all the annoyances in the bike world, curved seat stays are low on my list. There are so many more hate deserving things - bike 'fittings', people's obsession with wider tires on road bikes, 7 or 8 BB standards, etc, etc.

Sometimes a little bit of flex, appropriately designed in, prevents more serious problems.

Pinarello did the same thing along with the Dogma and Prince. They even made the forks crooked.

You call them “crooked”, I call them “curvaceous”.

Just don't see how a curve in a seat stay or chain stay will improve ride quality unless the entire rear end is designed to flex more than a fraction of a mm. Tire pressure, TPI, material and size will have a greater measurable impact on ride comfort than a bent tube on a frame.

I can tell you there is a difference between the straight stay CAAD3 and the wishbone stay CAAD4 and later Cannondales in ride quality.
