Thanks.
I am not an engineer so I can't say for sure. I've developed them with Stayer Cycles and we've built quite a few of them without issues.
My gravel bike has two regular straight Columbus stays and my fixed gear (former gravel bike) has wishbone stay. They are built almost identical in technique and tube choice and geometry is very similar and I can not feel the difference.
Wishbone is made from T45 steel which is absolutely the stiffest aero industry tubing. For road and rando style bikes we use a 12.9mm tube and off-road stuff a 16mm tube. I make the top part of random scrap from forks og chainstay and Stayer Cycles bend theirs custom out of t45 I believe.
Longtime lurker, love this thread. I've noticed that some (all?) of your frame builds share the skinny mono seat stays. I think it looks absolutely stunning, but does it have any impact on the stiffness of the bike?
