No more heat buildup at the rim, incredible modulation, predictable and powerful braking in wet and dry conditions -- the list goes on. These are the advantages of moving to a disc setup on your road machine. And so, with the introduction of SRAM's new Red 22 Hydro R (hydraulics for the road) braking group, a specific rotor was needed to complete the system. SRAM took the design of its AVID HSX and gave it a few tweaks for road use. What you receive is the tested design of the heat-shedding HSX, in a package engineered to give you the best braking available in a road groupset.

SRAM's HSX Heat-Shedding Rotor was designed to seamlessly pair with the new Red 22 Hydraulic Road Disc (HRD) setup. The two-piece stainless steel and alloy design utilizes cross-drilled technology for significant weight savings without compromising durability. The new design promotes heat regulation, and shaves around 10 grams over previous AVID models. The cross-drilling also sheds water quickly, resulting in increased stopping power in wet weather.

Because the alloy conducts heat more efficiently, the alloy carrier on this two-piece rotor allows heat to dissipate more quickly than similar one-piece designs. SRAM recommends using the 160mm rotors for pavement and the 140mm size for off-road/cyclocross use.

SRAM has placed a 250lb rider/bicycle weight limit on the 160mm rotor, recommending a bump to a 180mm if need be.

The SRAM HSX Heat-Shedding Rotor is available in 140mm, and 160mm sizes. It uses the IS 6-bolt mounting pattern.

Here's what others have to say...

would like to get the SRAM hydro braking...

would like to get the SRAM hydro braking system. I have a pair of Zipp 404-aluminum rim wheels. I have SRAM RED group. I would like to use the wheels I have. Can this hyro system work with my group?

I would hope you have received an answer to your inquiry in this time - but in case anyone else is reading your question with similar equipment...
This rotor, similar to most aftermarket rotors, uses a 6-bolt mount, requiring a 6-bolt hub or the appropriate adaptation (though I do not recommend adapting centerlock hubs - regardless of the hardware available to do so). If you already have disc brakes, and are simply wanting to use/change to this aftermarket friendly 6-bolt fit, I would recommend having your 404's laced with new hubs.
Also, if you have a road/cross bike and ride in an area with hills, or simply like to build up speed when you can, I would recommend 180mm rotors at the ~200lb mark even though SRAM wants to sell their 160mm to 250lbs - otherwise the 160mm should be fine.

Not sure that siliconvoid is aware that zipp only uses 6 bolt. I am using these on zipp 303, and they work ok. I am not totally happy with the fit. For some reason I have had difficulty getting these to not rub on my brakes where other discs don't have the same problem.
