Weighing 890g (with GXP bottom bracket), the X7 crankset isn't astonishingly lightweight – about 100g more than the carbon SRAM XO and 30g or so more than a 2010 Shimano Deore XT triple. But it does feel substantial when you’re driving your weight into it; it’s not flex-free (no cranks are) but it does convert effort into drive efficiently. bikeradar

TRUVATIV’s crank engineers threw away the old standards and developed a new chainring geometry from the ground up. They precisely paired the different-sized chainrings and redesigned where and how the chain engages with the rings. By aligning the chainring pick-up rivets to the chain pivot pin—rather than the middle of the chain link—you get double the shift opportunities.
