Why We Like The HS2 Rotor

Designed to reduce braking noise and improve heat dissipation, the SRAM HS2 rotor helps our bikes stop faster than ever while staying quiet on steep, sustained descents. The HS2 is thicker than previous SRAM rotors, measuring a full 2mm thick, and it uses a new brake track pattern that increases traction against the brake pads. These features work together to improve stopping power, while the recessed spokes with thermal dissipating paint keep the rotor running cool.

Improved Stopping Power

I've used it several times

I was stoked to see this rotor improvement from SRAM. I don't know how they based the increased braking performance but it works as advertised. I mounted the 220 in the front and 200 in the back. Besides looking stylish, it's provided a lot more confidence on short, steep descents. I've yet to try them on a long, steep descent so I can't say anything about brake fade. We'll see...

Warped, but After Fix = Awesome

I've used it several times
Size Bought:
220 and 200
6' 4"

I put a 220 on my Fox 36 and a 200 in the rear on my Slash 9.8. I run Code RSCs. I am upgrading from the old style Sram rotors, which are quite a bit thinner. The 200 rotor was warped when I got it. Nothing a rotor truing tool couldn't take care of, but I wish it would have been true from the factor. The warping wasn't too bad. The performance is unreal compared to the old style. I had to spend a bit of time really spreading out the pistons to accommodate the thicker rotors per Sram's instruction, but they clear great in the previous generation (Pre 2023) RSCs. The stopping power is awesome. A massive improvement. The biggest improvement I noticed though was a huge reduction in brake fade. I went to one of my favorite downhills, hit start on the strava, and went as hard as I could for the 3.24 mile downhill segment. Lots of switchbacks after long rocky straights; great for testing out brake fade. They were flawless. Even with the RSCs, I would get a little brake fade with some whining on this segment towards the end. Hardly any fade at all and not a squeak when the rotors were at their toastiest. The new design is a huge upgrade I would recommend to anyone with RSCs. 5 Stars. It would be less if I factored in the slightly warped nature of the 200 rotor when I got it, but that is pretty common and a simple fix. My review is solely based on the performance of the rotors.

Warped and no help from Backcountry

I've used it once or twice and have initial impressions

Got out on these for the first time this season, and brakes were surging. After troubleshooting and a ultimately getting out the bogey gauge, found that one had a thick spot and the other was pretty warped right out of the box. Unfortunately after calling Backcountry, was advised that they don't handle SRAM warranty claims, no returns since it's past 30 days, and I would need to take it up with my local bike shop. Lesson learned, no more buying bike parts from Backcountry! No support available. Keep it local.

Nice but warped right out of the box

I've used it once or twice and have initial impressions

Bought 2 220s. Both were warped right out of the box. One had about 0.15 of run out. The other close to 0.10. Now I have pad drag with brand new pads and rotors even after adjusting calipers, pistons, and bite point. Not really that stoked to see that with a $70+ rotor brand new out of the box. Beware if you don't have adjustable bite point.

Best Rotor Yet

I've put it through the wringer
Size Bought:
5' 8"

From SRAM. Have installed these on several bikes now with organic pads (Utah climate) and have had exceptional results. The common sense behind these rotors is nothing more than basic. But the fact that SRAM finally did it makes me happy. I will only be buying these rotors from here on out when it comes to SRAM. Thanks for bringing these in!

Crazy Good Rotor

I've put it through the wringer

Yes its a metal disc that stops your bike but this is a really good metal disc that REALLY stops your bike. Upgrade from 200mm to 220mm. Little to no fade on long downhills.
