Trapezoidal tubes allow for the dispersion of shock forces between the top tube and down tube. At the riding sag point, most of the shock forces are directed along the top tube. At suspension bottom-out, at most critical points, the rear shock rotates and shock forces are split between the top tube and down tube via the single-sided support strut.
The Suspension kinematics are designed so that the suspension feels the same for different sized riders. Small bikes are less progressive, Medium bikes more and Large bikes the most. Similar shock tune, & similar rear triangle used across sizes, but the suspension linkage is size specific. This is designed to rotate the shock more - give more mechanical advantage/leverage over the suspension to the lighter (smaller rider), and to the bigger bike, give less mechanical advantage - resulting in more progressive suspension.
Front derailleurs are dead! 1 X Drivetrain means a single chaingring in the front and multiple gears on the cassette. Most popular setups is 1 X 10, 1 X 11 or 1 X 12 With that comes a wider main pivot bearing stance for increased stiffness.
Asymmetric tubes allow for the dispersion of shock forces between the top tube and downtube. At the riding sag point most of the shock forces are directed along the top tube. At suspension bottom-out, the rear shock rotates and shock forces are split between the top tube and downtube via the single sided support strut.
Burst flex suspension platform utilizes flexible carbon seat stays, eliminating the need for a rotational pivot (bearings or bushings) in the rear triangle. Carbon fibre's properties work alongside the shock and leverage ratio to create a cohesive suspension platform. Elimination of a pivot point results in a lighter frame that requires less maintenance.
Optional storage box for spares or nutrition without reducing bottle count. Can be detached when you'd rather save the weight. Top-opening zip for easy access while riding.
Metric shocks perform better and have optional bearing hardware for low friction rotation, supported on the rocker side.
The massive main pivot uses angular contact headset bearings, with the larger 52mm bearing used on the drive side to cope with the additional chain forces. The angular contact design allows for bearing wear to be tightened out - the same as would be done at the headtube.
As modern XCO and XCM courses become more technical, we've adapted the bikes to suit not only the current trails, but also where XC is headed. Slacker head angles and longer wheelbases, along with other geometry and suspension tweaks allow for a bike that is more capable and forgiving on the downhills, but does not sacrifice any uphill ability in the process.
Front bottle is slightly offset to the drive-side of the frame for ease-of-access and good visibility when reaching for hydration mid-ride. Two bottle mounts in the main triangle. When it comes to water bottles, two is definitely better than one.
Don't leave setup up to chance, line up the rocker notch with the marking on the seatstay to guarantee perfect sag setup.
By triangulating the tubes it was possible to negate the need for a support strut on both sides. The role of the support strut is to split shock forces between the top tube and down tube.
The structure is mainly composed of T700 UD carbon fibre. Offering equilibrium in stiffness to strength ratio. Rear triangle is constructed with high-modulus carbon fibre to ensure indefinite fatigue life of the flex stays. UD carbon fibre has absolute strength in the direction of the fibre. Strategically controlling the fibre lay-up, produces a matrix that is stiff where desired and strong where necessary, with minimum weight addition. The frame is finished in a 3K Twill weave for a robust composite surface that can withstand any demands exerted by the rider.
