I installed these a few weeks ago to replace my 2010 SRAM Red calipers on a Focus Izalco. The installation was a breeze as the cable housing length did not have to be latered front or rear. Centering and adjusting them was a breeze. I am running Easton Carbon rims so my goal was to increase stopping power when riding with my hands up on the brake lever hoods. I would say there is at least a 20% improvement over the old SRAM Red with the cam action of the Aero when using the same amount of force. I also noted an overall weight savings of 40 grams for those weight weenies out there. I would recommend these if you are running carbon rims and need a little more braking power.
