Debuting in X9 and X5 trim, they’ll be available in 170 and 175 crank arm lengths with GXP spindles. Both use their 2×10 chainrings, and retail will be $314 (€280) and $169 (€151) respectively. Chainring combo is a smaller 36/22, and, from what we can tell, they’ve been optimized to improve chain/tire clearance versus their standard chainrings. BCD is a smaller 104 compared to the 120BCD on standard X9 cranksets.
UPDATE: Weights are 871g (X9) and 955g (X5) with chainrings and GXP bottom bracket. They’re designed with a 66.5mm chainline. The X9 uses hollow forged aluminum crankarms. The X5 gets forged, asymmetric arms.
