Galfer does:
Thanks! If you compare the Chinese eBay rotor to Galfer.... some things I see as significant: Even though both use opposing slots; look where the slots in the Galfer rotor go, and end up. Rather than terminating near a thin edge, the Galfer slots all point at the 'meatiest' part of the rotor 'petal'... leaving a lot of ductile Iron surrounding the slot. Nearly equal on all sides of the slot. That will promote uniform heat transfer. (Interesting to see the 'Patent Pending' embossed right onto that rotor, isn't it?:rockon
There's a limit to how efficient metal is at conducting heat, and the coefficient of expansion that follows that heating. Localized 'hot spots' will not expand in a uniform manner. Warpage, stress points, etc. etc all follow bad design. Remember the Vega motor, with the cast Iron block and the Aluminum head?
Maybe the Design engineer at the 'knock off' plant knew this, and did the appropriate calculations for the worst case braking load for every bike that this site lists, in that 'Engrish' translation. Maybe it's not some fly by night outfit that doesn't give a rat's patootie about any liability because they have found the biggest sewer in the world to dump marginal product into. There is virtually NO policing of eBay sites.... eBay is not responsible for what you buy there; they just charge a percentage for putting potential buyers and sellers together. No matter what, they make money.
If the bolt pattern lines up, and the brakes work...... all is good, right?
