Hooray for innovation

really light, solid cranks. i ride all mountain/enduro and these have stood up the the beating just fine. the 156 q factor issupposed to be more effecient, but it depends on your natural stride as well as chainstay clearance with your frame. also, someone at sram was having a smart day when they decided to redesign the bolt holes to allow you to switch chainrings without pulling the crank. props.
