This is the BB30 version of the X9 crankset for use with BB30 or PressFit30 frames/bottom brackets The X9 crankset does a great job at offering you a quality crank that performs to task, is lightweight for its class and works great under stress and load. The hollow and forged crankarms are brushed and anodized for stiffness and durability. The one piece, 4-arm spider which is attached to the arm does a good job at eliminating movement and flex. The X-Glide chainrings are ramped and pined for quick and precise shifting action. The outer ring is anodized, while the inner is treated for added durability. Black anodized alloy chainring bolts hold everything together.
The X9 2x10 crank requires a SRAM/Truvativ GXP bottom bracket to assemble to your frame. We offer this crank in the 26/39t option as we have found this to be the industry standard gearing. Mate the crank with an 11-36t rear cassette and your riding options are pretty much limitless. The X9 is for 10 speed drivetrains only and is compatible with all SRAM 2x10 systems.
