You're reviewing: SRAM GX Eagle Boost Groupset GXP - 12 Speed

SRAM - 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.
