New columbus flat mount option

[tim to]

While admiring the amazing craft at the Philly Bike Expo I saw this setup from Columbus to help address flat mount. These were special s bend seat stays pre-indented to mate with a flat mount cast piece. Generous curves at the bb to accommodate wider tires and road cranks. Looked really good and appears it would be pretty easy to implement. I appreciated seeing this and would consider building with it. I don't have machine tools to accurately do the two common paragon designs (the barrels or the plate) and had done a bike with the long low mounts... but prefer to have more chain-stay and less drop out. I think this setup would do the trick. FWIW!

saw that too.  pretty cool solution.  That chainstay was heavy as balls though, I presume to allow for the crimp.  It would be cool/probably more time than really available, to figure out a way to make that bend and crimp on other stays and use the little tab to braze or weld on.  Was a really neat and helpful design for sure.
