• OUR ENGINEERS PUSHED THE BOUNDARIES

    Optimized tube shapes, a more compact frame design, exotic hi-mod materials, and a dual upright, reinforced swingarm push strength and stiffness on this gravity defying cross country rocket ship. The Mach 4 SL balances the diverse needs of the modern cross-country racer; it can be competitively raced on a short-track course one weekend or at an epic endurance race the next. It’s the right combination of comfort, control and speed that makes the Mach 4 SL such a pleasure to ride. - MOUNTAIN BIKE ACTION
  • LITHE

    A new frame that weighs less than our impressively light Trail 429 frame. Heck, this frame weighs only 45 grams more than our featherlight Mach 4SL. We’re replacing the beloved Mach 5.5 with a 140mm ripper of a bike that weighs less than many dedicated XC machines. Super-low standover; small kittens and playful cats rejoice!

    FAST

    Incredibly capable dw-Link suspension kinematics allow 140mm of travel to pedal with more snap and climb faster than many 120mm bikes. Serious light weight. Cheetah chasing down an antelope acceleration. The soul of a trail shredder with the legs of Usain Bolt.
  • EVOLUTION OF A CLASSIC

    This latest iteration of the Trail 429 is evidence of our constant quest for peak performance. We’ve broadened its capabilities without sacrificing its legendary sharpness: slackening the head angle just enough, increasing the reach, and introducing a flip-chip to allow fine tuning of the geometry toward either the rowdy or racy ends of the spectrum.

    OUR STRONGEST, LIGHTEST, CARBON FIBER CHASSIS

    Through continued evolution of our proprietary Hollow Core carbon frame construction, we carved more than 300 grams from the chassis, achieving an XC-race frame weight with incredible all-mountain strength and stiffness, on par with dedicated flyweight race bikes.
