Carbon Tuned Construction: The Eagle crankset was born from a completely re-engineered construction using SRAMs Carbon Tuned technology, making it light & exceptionally strong. It has been designed specifically to handle the aggressive terrain, rough lines through rock gardens & big drop-ins. To top it off, the advanced, modern carbon construction makes this arguably the most stylish crankset on the market at present. Technologies: The SRAM Eagle crankset is the lightest, strongest & stiffest crankset they offer & the most technologically advanced that they have ever created. Using a high tier technological design & construction processes, SRAM has made a lightweight carbon crankset that can tackle any terrain, in any location & at speeds a mountain biker can only imagine. BB30: Aside from the serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability & stronger crank construction. Carbon Tuned™: Strength & stiffness where you need it, lightweight like you want it. Proprietary SRAM carbon lay-up design increases thickness & stiffness at critical stress areas. Tapered, terraced, carbon architecture ensures the greatest weight savings without compromising strength. X-Sync 2™: The X-SYNC 2 Eagle is the next evolution of SRAM X-SYNC technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC EAGLE™ design reduces friction & the accumulation of mud, grit & grime.
