BUCKLOS 160mm 180mm 203mm Floating Disc Brake Rotor, Stainless Steel MTB Brakes Rotors with 6PC Bolts, Ultra-light Floating Disc Rotor fit Mountain Bike Road Bikes BMX（Black、Red）

These discs were exactly what I was looking for to complete my Mongoose Aftershock build. I used a BBR disc brake adapter (B00VSH3R5O) for the rear mount and calipers from the BlueSunshine (B076BV879V) BB8 brake set (note that the 48mm threaded hub adapters in the BlueSunshine kit are not compatible with the mounting spacing on these discs). I especially like the red anodized spokes on these discs as it fit with some of the other subtle red accents on my build. The build quality is great and they were straight and well aligned once mounted to the hubs. After getting them adjusted and dialed in they work very well. Keep in mind the mounting holes on these are centered on a 44mm diameter and are not compatible with some of the other mounting hubs with a larger pattern used on some e-bikes. I mounted these disks to DONSP1986 hubs (B08NDMPS4S) with built-in disc brake mounting accommodations.

Great strong rotors, quiet, strong stopping power, perfect fit, plus good looking too.

Absolutely will buy this brand again when needed, but it probably will be a while. Great quality product. Light weight, durable, and SUPER fast breaking power. Extremely quiet, even when wet, no squeaking. NONE! I used to get about 125-150 miles on a set of pads. Same pad brand gets now at least 300+ miles of use! I definitely recommend these rotors. Just wish they came in a two pack. Oh yeah, the color matches my bike perfectly. But that's just aesthetics.

Only giving it 4 stars because of the fair price, if the price went up it wouldn't be worth getting.The rotor is thin and brake pads don't contact the entire rotor. It's not a problem when the pads are new but when they wear down a little they catch the rotor in 6 spots as it rotates. Other than that, it looks nice and they haven't broke yet.I would buy more of these if they had 180mm in purple.

Value here is ridiculous. Using on a spare wheel set with Hope brakeset, was in a rush and tried due to hearing good things. Fit is perfect, one rotor of two was slightly out of true due to shipping (shipped in cardboard sleeve only) but easily tweaked and has held true for a month. Bolts included are torx and seem of the same quality that avid ships, no issues for me using torque wrench. The finishing grind of the baking surface is not radial like high end rotors but they function very well compared to hope rotors.

Not that the weight makes that big of a difference, it's noticeable when holding them. Main reason for purchase was the color and build design to match the all alloy Bucklos Zoom 4 piston hydraulic brakes. The 2 piston, wired OEM brakes that came with my Ebike were not bad, but these are considerably better when matched with the 4 piston. Bought as a total set which saved a few bucks, they were easy for me to install and again, while not necessary, it is a very cool upgrade and I'm glad I did it.

Pretty warped. Looks decent. But does not work as intended.
