It comes ready to rip with an Alpha NEXT Platinum frame, Fox performance suspension package with 145mm/150mm travel (rear, front), alloy Bontrager Line wheels, and a SRAM Eagle 70 transmission that keeps shifts smooth, even under load. It's topped off with 4-piston SRAM DB 8 hydraulic disc brakes to keep you stopping on a dime.
