RockShox's Monarch XX is a wolf in sheep's clothing. It's got tons of heavyweight performance with an air spring's weight. So, it's light enough to race on and tough enough for hard-charging trail bikes. Perfect. Its oversize aluminum construction delivers smooth action, and the Solo Air spring makes set up a snap. Plus, setting your sag is unbelievably easy with the anodized gradient marks on the Fast Black piston. And for those long fire road climbs, sprints during races, and riding from your house to the trail, you've got RockShox's XLoc hydraulic remote lockout for the ultimate in efficiency.
