On Solidworks the shapes and kinematics are fine tuned and (FEA) finite element analysis can be run on the frame to analyse stresses. Our engineers then spend time with the factory to meticulously work out the carbon selection and layup for optimum strength and stiffness to least possible weight. The frame has to pass rigorous lab testing before the first riding prototype rolls out of the factory.
What: Moving the rider forward. Better pedaling position on climbs and better traction on descents. How: Shorter stem, Wide bars, adapted geometry (longer front triangle, steeper seattube, slacker headtube) and less fork offset. Moving the rider forward in relation to the BB, whilst keeping the rear-end as short as possible Why: Benefits across riding disciplines. More control, better front wheel traction. Utilizing bigger muscle groups to aid pedaling. Centralized weight improves balance, while the short rear end improves handling.
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 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.
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.
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.
Stratos features high quality Surface carbon rims built on DTSwiss 350S hubs. With a 21mm ID, and a combined weight of 1475g for the set, this is a stiff lightweight and super strong wheelset ready to tackle the most demaning XC courses. Surface wheels are tubeless ready.
The structure is mainly composited of T700 UD carbon fibre. Offering equilibrium in stiffness to strength ratio. Rear triangle is constructed with migh-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.
