Does anyone know is shimano has patented their design?

I am a personal fan of FRM, but is this legal?

Your thoughts appreciated.

its legal, cause shimano copied the design from a lot of other manufacturers. Bullseye had 2 piece cranks like 25 years ago (seriously) Sweet had 2 piece cranks with outboard bearings 10 years ago. This isn't a new design, and FRM isn't the first company to try to improve on shimano's design. Race face and FSA showed prototypes at interbike.

Kia Ora.

It's the way they all seem to be going.

Any idea on the weight? I use the new xtr's and love the stiffness. I didn't think it would make a difference but it does. Converted a set to single speed as well
