KEY FEATURES
Yes, the frame allows for an interally routed dropper seatpost.
No, the Stratos AL range has sheathed cable routing. Which means Cables run underneath a polyurethane sheath on the downtube, which hides the cables but can still be removed for ease of maintenance.
120kg - combined weight of bike and rider (including all kit).
Stratos uses headset bearings in the main pivot. These are Token C83-TBT bearings. Contact your local Silverback distributor for more info.
Intermittent cleaning is the only maintenace IGUS bushings require. Ensure they are dry and clean of dust with a paper towel. Do not grease IGUS bushings since this will attract dust - IGUS bushings are self-lubricating and do not need to be greased.
Aluminium has a limited fatigue life, meaning that it will always fatigue eventually. By using a bearing at the rear pivot instead of relying on frame flex, we can greatly extend the life of your frame. Since carbon fiber can be designed for indefinite fatigue life, we can be confident that Stratos CF will not fail by fatigue.
No. The entire Stratos range is designed with wide range 1x drivetrains in mind. This allows for wider bearing stances and a stiffer frame
By reducing peak stresses at points in the frame, the entire bike can be constructed lighter. On a full suspension bike, this becomes even more important to have ‘balanced’ kinematic through the middle plane of the frame, that is not bias toward the drive or non-drive side. The drive side sees long periods of loading, of relative low to medium force. Where the non-drive side sees momentousness loading, of a far higher magnitude. So very different forces – localized to a specific side.
POP geometry or Position of Power geometry moves the rider in a more efficient riding posture, more balanced climbing and descending position and engages larger muscle groups for power delivery.
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 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.
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 accommodate much longer droppers, giving the rider more options and freedom of movement.
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.
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.
Get the great looks and smooth lines of carbon fibre, without the cost implications.
The SX Eagle 1x12spd drivetrain offers plenty of gear options for both climbing and descending. A 12 Speed SRAM Eagle drivetrain, compliment the Stratos' versatile nature.
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.
When is comes to water bottles, two is definitely better than one.
