To the benefit of anyone who rides a road bike, SRAM pioneered road hydraulic brake systems, although they'll be the first admit that the initial systems could still bring even better performance and reliability to the table. After starting with a clean sheet of paper, SRAM drew up the 2015 SRAM Red Hydraulic Rim Brake system, hitting the reset button and creating a superior braking platform against which all other rim brake systems shall henceforth need to be judged. To reboot its original road and cyclocross hydraulic braking systems -- which, again, were already ahead of their time -- SRAM pulled apart every molecule of their anatomy to find room for improvements. The lever body, housing the reservoir and master cylinder, was reconfigured for more efficient internal spacing while at the same time boosting strength and stiffness, resulting in solid, consistent performance, regardless of braking or weather conditions. The master cylinder piston itself was also completely revamped, receiving an all-new bore design and new seals, after being subjected to thousands upon thousands of testing hours in every temperature and performance setting imaginable. The goal was absolute reliability, and the new system delivers. SRAM was far from finished with updates, however. The new higher-capacity fluid bladder -- the part of the system designed to maintain braking feel and consistency in compensation for pad wear -- was also redesigned to improve fluid flow, so your brakes feel as great brand new as they do after a season of racing. At the rim, where the action happens, the smooth action of the powerful caliper translates into incredible confidence and control, allowing you to push harder and let the reins fly looser than they ever have. Opening wide enough to accommodate even the widest rims on the market (such as Zipp's Firecrest rims), the brakes are easily installed with SRAM's Connectamajig, allowing simple, clean hose connection without the hassle you would think would .
