Overview

Stratos AL 2.0 is the mountain bike every recreational rider can enjoy. 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 groundbreaking 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!

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.

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.

  1. John

    Bought this bike, really liked how it looked, specs also looked great.

    But unfortunately having a few issues after the first race – headset bearing is creaking badly, cable cover on frame has come away (seems tape has lost its stickiness), dropper post has some movement in it.

    Hoping these are simply teething issues that I can with Silverback on to sort these out, as the bike is brand new – will update the review once i have feedback.

    As promised, an updated review on this bicycle.

    Since my last review, we have:
    1. Had the bike setup redone (by Silverback, thank you)
    2. Changed stock grips to chunkier grips (a personal preference)

    Having now ridden a few hours on this bike, I can say the bike is now as good as I hoped it would be.

    After a few years on a hard-tail, this is my first soft-tail and is really proving to be a good ride. Bike turns quick, gear changes are good, suspension works really well.
