Whether it's a World Cup XC battle, an epic stage race, or hot laps on your local loop, you're going to be the fastest cat out there aboard Norco's Revolver 7 SL XX1. Its feathery, stiff high-modulus carbon frame lets you float up hills, while the 100mm-travel RockShox SID XX World Cup fork delivers premium control with pinpoint steering precision. SRAM's sleek, class-defining XX1 drivetrain gives you 11 speeds to tackle any terrain, and SRAM's Guide Ultimate brakes give you solid braking everywhere. Add uber-light, uber-stiff ENVE carbon rims, lace them to DT 240 hubs, and then wrap them in fast, tacky Schwalbe rubber, and you've got the ultimate XC wheelset. Adding a carbon ENVE carbon bar, stem and seatpost into that mix just feels like cheating. Looking for the ultimate 27.5/650b XC weapon? This is it.
