Review on 2Pcs 160Mm 180Mm 203Mm 6-Bolt Disc Brake Rotor Stainless Steel Bicycle MTB BMX Road Bike by Chad Cypert

So first : I suspect that although these are marked as "Avid " brand … these are actually a knock off . The Branding logo is lightly laser etched onto the surface , while the real Avid ones are stamped deeply right into the disc . Mine were warped right out of the bag . Before I returned mine I purchased some genuine Avid discs which confirmed that these are fakes . The real ones have almost no flex because the steel is much harder and slightly thicker ( these flex easily ) the real ones are stamped with Branding and sizing information ( these are laser surface etched ) . The real ones have a slightly larger ( 1/8 ) surface / contact area where the pads touch ( on these if you’re using Avid BB5 or BB7 your pads will try to contact where there is no disc ) . This is not unusual though . I have purchase 5 different sets from 5 different sellers all labeled "Avid " . Everyone has been a fake . So - if you have a cheap bike and don’t care - get these . But if you want discs that won’t overheat and warp and are genuine … avoid these and pretty much most of what’s being sold here on amazon !
