  • XC Materials

    Our X/C race bikes are constructed using either our proprietary FOC carbon fabrication process for minimal flex, or our lighter-weight speed metal for easier climbs.

    Our proprietary FOC methodology for carbon frame fabrication allows us to make a bike frame that doesn’t flex in ways it shouldn’t because of pedaling, steering or impact forces. Basically, you get a frame that rides the way you want without sacrificing the strength and durability you need.

    GT Speed Metal™ is a light-weight aluminum construction designed to be light enough so you can climb with the XC crowd, with the ability to leave them comfortably behind on the way down.

  • Independent Drivetrain™

    This suspension does its job. Period. Because it operates independently of the drivetrain, the suspension can focus solely on its intended purpose – a smoother, faster ride – without making compromises in pedaling efficiency. And because it’s an inherently simple design, it’s easy to set up, ride and maintain. Sound good? Good.

  • Triple Triangle™

    Originally developed to extend the frame life, stiffen the rear triangle and thus create a faster, more responsive ride, the Triple Triangle™ frame has transcended its role as just another tech story and become an iconic symbol of who we are and what we stand for.

  • Tapered Head Tube

    Our forged, tapered head tube affords the same steering response and stiffness without suffering a weight penalty.
