Bontrager has a limited edition run of their Speed Limit road brakes in HCM (High Compression Molded) Carbon Fiber.  Only 500 are being made, and the first 150 are shipping now, with 100 to 150 more coming in each month until they’re gone, according to their rep.
Weight is 220g / pair, which comes pretty darn close to the Feather brakes we reviewed and the infamous Zero Gravity offerings.  MSRP is $399.99, they have a 5-year warranty and they can be ordered through your local Bontrager/Trek bicycle dealer.

Wide carbon fiber arms keep things stiff, and they use Stainless Steel hardware for durability.
The PowerAmp linkage (above and below) gives the brakes the same leverage ratio throughout the range of movement.  Bontrager claims it provides dual-pivot power with single-pivot simplicity.
