THE PRIVATEER'S ULTIMATE ENDURO RACE BIKE Seriously. The Megatower’s big wheels, long-travel and tough carbon fiber chassis delivers the high-speed security traits of a race bike. Yet the relatively steep seat angle and size-specific geo maintain the Mega’s mega pedaling ability, elevating its reputation as the perfect choice for big gravity rides, park laps and enduro racing. Blind confidence on blind terrain VPP™ suspension can be optimized to strike a balance between pedaling efficiency and all-out bump-chomping prowess. The Megatower is exceptional at absorbing the biggest hits so its rider can charge harder, with more confidence, in the very worst terrain. But because it's still pedal efficient, getting up to the best, highest trails isn't a chore like some other bikes. Sensitivity and constant traction The Megatower's low leverage ratio to provide a more damped, controlled feel at speed. Lower anti-squat reduces pedal induced firmness and provides excellent square edge bump absorption, which gives you a greater margin for error when taking blind risks on wild trails. Thought out for privateer racers The Megatower's low leverage ratio to provide a more damped, controlled feel at speed. Lower anti-squat reduces pedal induced firmness and provides excellent square edge bump absorption, which gives you a greater margin for error when taking blind risks on wild trails.

STOMPING GAPS AND STAMPING PASSPORTS Load up the van, hit the road, climb a mountain, hammer it back down, huck the gap, throw the bike back in the van, drive to the bike park and do laps on laps. Hell, you could even rock up to the startline of the world's wildest races. The Nomad’s forte is being ready and willing to go wherever, whenever. The only thing it needs is a rider willing to press send. All the travel anyone needs in a single-crown bike intended for the steepest and deepest of trails. VPP™ suspension can be optimized to strike a balance between pedaling efficiency and all-out bump-chomping prowess. The Nomad is exceptional at absorbing the biggest hits so its rider can charge harder, with more confidence, in the very worst terrain. But because it's still pedal efficient, getting up to the best, highest trails isn't a chore like some other bikes. Sensitivity and constant traction On the Nomad, lowering the anti-squat reduced pedal kickback on big square-edge hits at speed, all while improving the overall sensitivity of the suspension to maintain traction at all speeds. Up and downhill. Flat-out bump control and tracking By reducing the starting leverage of the latest Nomad, we were able to improve body-weight influenced geometry stability throughout the travel. While reducing progression allowed the suspension to have consistently better tracking qualities throughout the stroke. Built to last Short, stout counter-rotating links connect the front and rear triangles to create an extremely robust chassis that reduces lateral flex. Simple expanding collet axles hold things together, pivots run on large diameter axles and bearings (which we offer free lifetime replacement for) and the lower link includes a grease-port for quick, easy maintenance. Frame stiffness tuned by size Bigger riders means bigger stresses on bigger frames. So we tailor stiffness for every size to make sure everyone gets the same ride quality. Details matter The details are completed by a neat mud flap to protect the rear shock plus tidy cable routing within the frame and swingarm, and rubberized DT protectors to shrug off strikes.
