    DYAD FIBER LAY-UP

    The Dyad lay-up schedule employed on our Dakota frames utilizes two different types of high modulus carbon fibers, applied in specific sequences and angles to maximize strength, stiffness and ride quality in the lightest possible package. The Dyad Supreme lay-up on the Team results in a frame that is 20% lighter and 15% stiffer!

    FEA OPTIMIZED FIBER DESIGN

    We use powerful, state-of-the-art, composite manufacturing software to analyze and perfect our lay-up schedule. The result is optimal stiffness, greater durability and lighter weight.

    29’ER GEO

    Its all in the numbers: a 70.5 degree headtube angle for fast responsive steering and stability at speed with no “flip/flop” feel. A 73 degree seat tube angle to puts the rider more directly over the pedals for an optimal pedaling position. With a cool, aggressively sloped top tube for the lowest possible standover on those large diameter wheels and a stiffer, more responsive frame.

    TAPERED HEAD TUBE AND FORK STEERER

    Riding fast with control requires steering precision, which starts with the front of the bike. Stiffening this area results in less wheel deflection, more wheel control. A tapered 1 1/8” to 1.5” head tube and steerer serves up a significant increase in rough terrain tracking and stability without much of a weight penalty compared

    to standard 1 1/8” systems since the steer tube wall thickness can be reduced. Adding a 15mm QR thru-axle hub/fork interface takes steering precision over the top.

    WHY PRESSFIT 30?

    The larger 46mm bore diameter of the Press Fit 30 BB system increases the frame’s bottom bracket shell providing a larger surface that increases frame strength. The key difference with Press Fit 30 is how the bearings are fitted into the frame. Bearings are housed in nylon cups that are pressed into the frame’s bottom bracket shell. Like BB30, Press Fit 30 uses the same oversized bearing that is designed for 30mm spindle cranksets. Advantages of Press Fit 30: Improved bearing-to-shell interface, greater bearing durability and simple installation.

    ONE AND ONLY

    The 1 x11 drivetrain philosophy is to make it simpler, lighter and more durable. Specific chainring tooth profiles, clutch-type rear derailleurs and wide range cassettes are developed for an incredibly wide gear range and maximum control without the need to chain tensioning devices or guides.

    WHY THRU AXLES?

    Securing the rear wheel to the frame by threading a 12mm axle into the rear drop-outs is not only safer, it’s stiffer. The rear wheel tracks directly in line with the frame, for more precise handling, so you can go faster with more confidence. The increase in stiffness of a 15mm fork axle improves steering & handling significantly. It also puts less stress on the fork’s internals, improving fork durability and performance. The hub drop outs provide a self centering feature for the wheel for fast, easy installation.

    TAPERED HEAD TUBE AND FORK STEERER

    Riding fast with control requires steering precision, which starts with the front of the bike. Stiffening this area results in less wheel deflection, more wheel control. A tapered 1 1 /8” to 1 1 /2” head tube and steerer serves up a significant increase in rough terrain tracking and stability without much of a weight penalty compared to standard 1 1 /8” systems since the steer tube wall thickness can be reduced. Adding a 15mm QR thru-axle hub/fork interface takes steering precision over the top.

    TUBELESS

    Benefits of a tubeless set-up are reduced rotating weight and the ability to use lower inflation pressures for greater traction without the risk of pinch flats.
