Slotting in just below the excellent Force groupset is the updated Rival group which now offers 22 gears, but unlike the Force group it is constructed from aluminium to help keep the price down. Featuring super-stiff, 5mm 7075-T6 CNC-machined aluminum chainrings, the crank utilizes the same X-Glide R precision-shifting technology pioneered on SRAM's revolutionary XX mountain groupset. Shifting is not just smooth, it's lightning-fast, with no "shift lag" as you wait for the chain to connect with the ramp pins on upshifts. The aluminum arms join a machined alloy spider, creating a tremendously stiff package that doesn't weigh all that much more than its carbon equivalents.
