    POP GEOMETRY, BURST PIVOT SUSPENSION. UNBEATABLE COMBINATION.

    Stratos AL 2.0 is the full suspension mountain bike every recreational rider can benefit from. Silverback's POP geometry makes it a strong climber and a balanced confident descender. The linkage driven asymmetric single-pivot suspension is tuned for optimal small bump sensitivity and big-hit compliance without power delivery penalties. The suspension curve is designed to offer full use of available travel. The Stratos AL 2.0 is based on the ground-breaking Stratos CF race-machine, but geometry is adapted to offer a more capable bike for the everyday rider. The component highlights for the Stratos AL 2.0 includes a 12 speed SRAM NX drivetrain and a RockShox Reba 120mm fork. XC, marathon or trails, the versatile Stratos AL 2.0 is the right mountain bike at the right price!
     Silverback Stratos Burst Pivot Suspension

    BURST PIVOT SUSPENSION KINEMATICS.

    BURST Pivot is the XC/Light Trail implementation of our popular BURST platforms. It combines great pedaling performance with a progressive end stroke to create a platform that reacts intuitively to different circumstances. Large bearings in the seatstay mounted pivots, near the dropouts, ensure a good service life.

     Tapered pivot and bearings

    TAPERED PIVOT AND BEARING DETAILS

    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.

    HYDRAULIC DISC BRAKES

    WHY IT’S BEST.

    1. Stratos AL2 shares the innovative alloy frame found on the AL1. The shape really has to be seen up close to appreciate the amount of detail that has gone into the design.
    2. Sheathed cable routing is discreet, easy to install, silent and very easy to work on at home - unlike classic internal routing.
    3. Stratos AL2 features a 12 speed NX Eagle drivetrain - this means easy climbing and a decent top speed. More than that, this means reliable quality and crisp shifting performance.
    4. AL2 comes as standard with wide bars and a short stem - this is an integral part of the POP geometry. This gives you more control.
    5. POP geometry or Position of Power geometry places the rider in a more efficient pedaling position, more balanced climbing and descending position and engages larger muscle groups for power delivery.
    6. AL2 features Crest wheels that's both light and super strong - perfect for the type of riding you'll be doing on the Stratos AL.

    ENGINEERING NOTES.

    ASYMMETRIC FRAME

    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 PIVOT SUSPENSION

    BURST Pivot is the XC/Light Trail implementation of our popular BURST platforms. It combines great pedaling performance with a progressive endstroke to create a platform that reacts intuitively to different circumstances. Large bearings in the seatstay mounted pivots, near the dropouts, ensure a good service life.

    DROPPER POST READY/COMPATIBLE

    With dropper posts becoming standard on all disciplines of mountain biking, this was a no-brainer; what's more interesting is where this technology is headed. Stratos can accomodate much longer droppers, giving the rider more options and freedom of movement.

    METRIC SHOCK

    Metric shocks perform better and have optional bearing hardware for low friction rotation, supported on the rocker side.

    POP GEOMETRY ADAPTED FOR XC/TRAIL/MARATHON

    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. Stratos AL has 120mm travel and has some geometry changes that give a slightly more relaxed ride that its carbon fibre counterpart, aimed at riders looking to spend longer days in the saddle or dabble in trail riding.

    SHEATHED CABLE ROUTING

    All the looks of internal cable routing, but without the hassle. Cables run underneath a polyurethane sheath on the downtube, which hides the cables but can still be removed for ease of maintenance.

    SMOOTH WELDS

    Get the great looks and smooth lines of carbon fibre, without the cost implications.

    TAPERED PIVOT AND BEARING DETAILS

    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.

    TWO BOTTLE MOUNTS IN THE MAIN TRIANGLE

    When is comes to water bottles, two is definitely better than one.
