Revolutionary Innovation. When advancements are continuously made to every attribute of every component, the result is overall performance that is simply second to none. And to real cycling enthusiasts, there is nothing more gratifying then achieving the ultimate ride. And the best part is we just keep making it better. This is what SRAM is all about. Sure, a casual rider will appreciate solid performance, reliability, dependability and all the standard qualities one would expect. But it's the riders who live and breathe bicycles who love us most because bicycles are what we love, too. In fact, they're our only love. Narrow minded yet forward thinking. Bike components are all we do - which is why we do them so mind-bendingly well. SRAM Corporation began with the goal of creating the absolute best shifting system and changed the cycling world forever with the introduction of Grip Shift. To support the innovation, we invested in Sachs Bicycle Company and built a state of the art manufacturing facility in Schweinfurt Germany. We had the vision and desire to expand our presence in the industry so we found the best suspension company, RockShox, joined forces with them, creating huge excitement in the global cycling community. Not content to stop there, we knew expanding our line with the best brakes, bottom brackets and cranksets would fine-tune the ride even more. So we teamed up with Avid and Truvativ. Now that we have achieved total drive train nirvana, we will continue to seek and deploy technological and engineering advancements, as we compulsively refine and redefine the pinnacle of the ultimate ride.
