Great technology can change the way you ride, and with the Avid HS1 Heat Shedding Rotor you'll be riding longer than ever. With a new cross-drilled design, the HS1 holds true to its name by efficiently shedding heat. It allows you to tackle the technical by riding the brakes to your heart's content without fear of overheating. More control, less weight, and minimal wear -- that's our kind of rotor.The Avid HS1 Heat Shedding Rotor is the next step in disc brake technology. The one-piece stainless steel design utilizes cross-drilled technology (think Merckx-era drillium) for significant weight savings without compromising durability. The new design promotes heat regulation, and weighs around ten grams less than previous models. The cross-drilling also sheds water quickly, resulting in increased stopping power in wet weather. The Avid HS1 Heat Shedding Rotor is available in 160mm, 180mm and 200mm size. It uses the IS 6-bolt mounting pattern.
Strengths: Quiet - I didnt hear much noise from back there.
Stopping Power - Felt great out there. Seem to lock it down when I needed it to.
Weaknesses: Durability / Strength - These came stock on my 2012 stumpjumper comp - I picked up the bike at the end of the season, so I got a hand full of rides out of the bike and on my last rip when I could feel at some point something happened I felt very slugish and had to fight the bike. When I was packing the bike up I found out my rear wheel barely free spun. I bent the rotor real bad, no idea when or how. But it was so bad the LBS mech couldn't figure out how I did such a bend and wasnt able to straighten it.
The mechanic told me that these rotors were real good and he's never seen a warp like mine. So I think it was my fault, must hit a rock or something. Either way it did happen and these seem to be the most costly rotors in the size/spec I need. Kinda frustrated it happened so early in owning the bike but sh!t happen right? From what I can tell a solid rotor. *the low rating is because it warped after so few rides, be it my fault or not, never had this problem on my mech tekro disc's I rode in the same trails for the 4 months prior.

Strengths: Bullet proof, quiet, consistant, makes Avid brakes work right.
Weaknesses: A bit heavy
The 8" heat shaeding rotor made my Avid brakes useable. I live at the bottom of a 3000' descent. It's a blast with some long descents and twisty single track. But it's really tough on brakes. The 6" stock rotor whinned, sqeeled, gobbled, and dragged after every ride. I was not going to be sanding rotors when I should be riding. The Formula brakes on my other bike don't need that! Instead of tossing the bakes I tried the 8" HS rotor on the front. Once set-up (Avids are a bit finiky), they work great. No probelms at all not. They are reliable, consistant, quiet, and don't fade. They make hte Elixrs perform as advertised. Highly recommend these rotors.
P.S. As with all brakes and rotors (esp. Avid), make sure you bed them in properly (gently)!http://www.bikeradar.com/gear/article/workshop-how-to-bed-in-disc-brake-pads-31337/

Strengths: My first time at Downieville I realized how much I still have to learn... ;-) As a result of that the 160mm stock rotors from the Avid CR's started to "fade" as they were getting hot: NOT the right time for weak brakes. I read about the HS1's and decided to give them a try. I ordered the 180mm rotors with adapters and after a short brake-in phase they behaved much smoother, better modulation, more "bite", are more quiet than the stock rotors. Don't expect miracles from getting new rotors, but they do behave much better.
Weaknesses: Ordering the right IS/post adapters can be tricky, since most Avid rotors that size are 185mm, while the HS1's are 180mm.
Effective and inexpensive upgrade.
improved modulation, less fading, less squeaky (more quiet)
Has anyone tried running the new HS1 rotors with BB7 calipers? I read that there could be issues due to the different contact patch of the BB7 calipers vs the hydro pads the HS1 was presumably designed for. But no confirmation from anyone who has actually tried this combo.

I have some avid hs1 that came with my bike, i got some shimano xt with Ice-tech rotors with an XT kit that i bought.
Dont know which one to keep. HS1 looks great, works great too I have no issues with them, XT doesnt look as good, are heavier than the avid.
So, are the XT way better than the ... Read More »
I was just wondering whether anyone has any experience with these 2 rotors?
Both are supposed to shed heat but the Ice Tech ones are heavier.
Do they par up to each other in terms of performance?Read More »
