Bibike2Pcs 140mm/160mm Centerlock Disc Rotor with Lock Rings

I was (pleasantly) surprised to see the "Racework" branding on centerlock rings. Having bought Racework products earlier I knew this is going to be good. So no surprises in the performance. Currently doing duty on Salsa Journeyer with GRX 810 calipers these are rotors are perfectly straight and work exactly as Shimano ones. I am using them with resin pads and there is no squealing sound even in the wet. I feel these rotors are slightly thicker than Shimano ones so the installation needed some fiddling of the calipers.All in all, good rotors on budget. Not the lightest though so if you are looking to save some grams, look elsewhere.

Rotors are solid for the price. The included lock rings seem slightly too large in diameter to smoothly thread into 2 sets of reasonably high end wheels (dt Swiss and industry nine) didn’t want to force it and potentially damage the threads on high end hubs. already had lock rings so not a big deal but something to be aware of.
