Building on the lightest, most versatile production carbon crankset on the planet, the Next generation G4 couples CINCH compatibility with an elegant arm profile that seamlessly integrates the crank arm with Race Face Direct Mount compatible rings and spiders. G4 is lighter weight (430g - 32T Direct Mount) with improved lateral stiffness; a critical advantage when the chain is under tension at extreme angles, like those resulting from a 1x system setup. If weight and stiffness are not enough, then futureproofing your setup with the versatility of the Race Face CINCH system should be. FEATURES Fully hollow carbon crank arms for maximum weight savings. 30mm spline interface CNC'd from commercialized super alloy, 20% stronger than 7050 aluminium. Removable spider offers the ability to convert between existing chainring standards while remaining flexible to future developments. SPECIFICATION Built for: XC Race/Trail Size: 170, 175mm BB Options: BB sold separately Spindle Diameter: 30mm Weight: 430g (32T direct mount, without BB) Chainline: Q Factors & chainline PDF.
