Quality and durability combine in the SRAM X1 crankset to deliver consistent performance every time out. Featuring SRAM’s X-SYNC tooth profile, the X1 crankset is engineered for complete chain control. Each tooth’s thickness is CNC machined to work seamlessly with the chain’s inner and outer links. And with five available chainrings, you can personalize your gear range to match the way you ride. Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction. With revolutionary advancements in bicycle componentry, like SRAM’s XX1, X01 and X1 drivetrains, mountain bike designers have been given almost limitless freedom to focus solely on the performance of the bike. Each advancement demands that the entire package works flawlessly. Aggressive trail and enduro riders have been increasingly enjoying the benefits of larger wheels, but many still view 27.5" and 29" wheels as a possible weak link. Which is why SRAM has developed an open standard with Boost compatible components for SRAM drivetrain, hubs and RockShox forks.
