Having thoroughly dominated the world of mountain biking since its debut only two years ago, SRAM's 1x11 drivetrain platform has gotten even friendlier with the introduction of the new X1 group, established as the value oriented 1x11 family below the top line XX1 and mid range X01 groups. This SRAM X1 1400 BB30 Crankset is for those of you riding a BB30 frameset who want to capitalize on 1x11 innovation, without breaking the bank. The X1 crankset comes in several versions, including the value oriented 1000 and the mid range 1200, but the 1400 is the best there is. It's lighter than the others, thanks to hollow forged crank arms, but it doesn't lose any stiffness to its solid armed sisters. Mated to a forged aluminum spider, in fact, the X1 is stiffer than most cranks on the market, even far more expensive competitors. Like the XX1 and X01 cranksets, the X1's X SYNC chainrings available in size from 30 to 38 teeth feature a special alternating offset tooth profile that locks the chain onto the ring to prevent dropping, even over the most abusive and bumpy terrain. The SRAM X1 1400 GXP Crankset is available in two arm lengths 170mm and 175mm and in two colors: Red and Black. It comes with a 32 tooth chainring and no bottom bracket.
