My question is if this optimized for Yaw X-Glide chainrings are going to work at the same level of functionality with a shimano derrailleur? maybe the answer in unknow, is the X glide going to have a different shape in dents or something like that?
This is their marketing hyperbole-
"The
X-GlideR Chainrings are designed for an optimized shifting performance with the Yaw front derailleur. The stiffer rings (5mm 7075-T6 aluminum CNC-machined) feature upshift rivets with an advanced design adopted from SRAM XX. CNC machining allows for precision control of each tooth shape, ramp, and nearly every shifting feature of the chainring. Chainrings, chain, and front derailleur are designed as a single integrated system for optimized performance."
Someone can correct me if I'm wrong, but in practice there will be absolutely 0 negative consequences of using a Shimano FD. The physical action of pushing the chain from one ring to another is no different between the derailleur brands. The Yaw FD angles itself in a way that basically eliminates rub in any gear combo, but it still pushes the chain off one ring and onto another just like a Shimano FD.
If there is any functional difference thanks to the "integrated" design, it is so small as to be imperceptible based on many people's experiences here.
Not sure what else you could be looking for, other than finding someone to tell you it just shifts like garbage unless you get a SRAM FD.
