160mm 180mm 203mm Disc Brake Rotor with 6 Bolts Stainless Steel Bicycle Rotors Fit for Road Bike, Mountain Bike, MTB, BMX (Stainless Steel, 2pcs)

These rotors are labeled as Avid HS1 discs and having compared them to other Avid brakes, I find no reason to doubt they're legit. Excellent design and quality. You can see in my image the design is essentially the same as the much more expensive TRP-29 rotors in the background, just without the TRP's slots of questionable effectiveness. My one criticism is that for MTB use, the small drilled holes don't clear out mud as quickly as brakes with larger ones. That tiny criticism aside, these are an amazing value for the money and an excellent choice for any application.

Bought these for my wife’s e-fatbike. It came with 160mm rotors and they were barely sufficient for the riding we do. The mountains of the Pacific Northwest are steep and on long descents the 160mm rotors got cooked.This kit is two rotors and they were true right of the package. The only trick was getting the right adapters for the Tektro brakes on the bike. The contact path on the 200mm rotors is wide, and the wavy edge means I wasn’t able to get the calipers as far inboard as I wanted. Any farther inboard and the wavy rotor edge would scrape against the caliper. I actually used a grinder to reduce the thickness of the rear adapter so I could get it as close as possible.Use sintered pads with these rotors. Truckerco makes a great pad that works with Tektro and Shimano calipers, and they now stop this bike like a boss.

no reason to pay more for mid grade sram/shimano just buy these. the ice tech Shimano are definitely better but these are the same as what goes on most bikes for a lower cost.

Great deal for taming the brake squeal I've been dealing with. Replaced the pads at the same time, bedded them in well and haven't had any issues. They don't seem to stop as well as the rotors that came on my bike. They are a bit narrower on the surface where the pads engage with some wider spots around the perimeter. Knocking a star off only for that, but I can get myself stopped fast enough and the squealing is gone! These are a high end manufacturer also, cannot remember the name, but good quality for the price.

Awesome deal very high quality for an honest price. Many others are way overpriced for what they are and do. Not saying that there's no garbage out there I'm saying there's a lot of these that people are paying 2 to 10 times as much for the name and the look where as functionality is the same and those makers will go as far as to pay a pro rider to say otherwise and abuse the cheaper ones to try to get their point across. I'm not stupid and am not having none of that.

These are great. They are sold as generics, but I can tell these were made by Avid, which is a great brand, so buy with confidence. Amazing price!

I ordered two pairs of rotors. Both were well made and completely flat, stamped with the Avid brand and the now discontinued HS1 model designation. After installing one set on a bike using BB7 brakes I noticed the pad contact area is about 2mm narrower than either Avid Roundagon or G2 Clean Sweep rotors. The HS1 rotors stop well with good modulation and are mostly quiet, however, I would recommend purchasing a G2 Clean Sweep for better stopping power and nearly equivalent cooling.

These are a generic version of the 203mm Avid 39A Alloy-AllStop rings. They are a great value and they give you two disks with mounting HW. There was aberration duality upon initial install, but it subsided once I adjusted the pad tolerances to 2mm( L & R) subsequent TLS gauging. The stopping power was reduced by 10.75NM per force applied effectively reducing momentum of mass by 7.48%. The OEM 165mm rings were woefully inefficient to reduce my applied mass of bike, body, and backpack approximately 210lbs to safe stopping distance with my needed requirements. 0-25mph with 15'.
