https://www.aliexpress.us/item/3256805673187010.htmlCuriosity got the better of me and I ordered these lightweight 6 bolt rotors for my gravel bike. I opted for the 180/160 pair. I figure for a non-loaded 7.5kg gravel bike, the lightweight design should be fine.The rear 160mm rotor bolted up with no issue, but the front 180mm rotor needed a piston reset, fresh pads and rotor alignment.
I want to compare them to the 160mm IIIPro floating disc rotors which I highly recommend in the 2x160mm configuration. I was thinking of getting the 180mm disc in that brand, but the weight gain was a bit too much for me.
