RACE TO THE TOP, KEEP THE RACING TO THE BOTTOM.

The CF2 brings unbelievable value to the carbon Stratos range. Bred for the most demanding courses the world over, the Stratos was designed from the ground up to trounce any terrain. Asymmetric design dissipates load based on impact magnitude and suspension position, alleviating stresses where it's most concentrated. Paired with 12-Speed Shimano SLX 12spd, 120mm Fox 34 Rhythm fork, and Surface 23mm alloy wheels, it sets the scene for competitive racing. CF2 is the perfect race bike for unsponsored riders. Sharing a frame with the top end Stratos, the CF2 specification is chosen to carefully balance quality, weight and maximum service life. Oversized tapered pivot and Burst Flex suspension makes for a stiff, responsive, extremely light and agile race bike. The included dropper post opens a new world of riding possibilities and line choices. Stratos CF2 leaves nothing to chance.

FINITE ELEMENT ANALYSIS

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.

ADAPTED POP GEOMETRY

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.

OVERSIZED PIVOT BEARINGS

WHY IT’S BEST.

  1. CF2 is a real mountain bike in every sense of the word. For the rider that pushes hard on the climbs, and even harder on the downhills.
  2. Hitting gaps, drops and technical descents without any drama is just the click of the included dropper post lever away.
  3. The beefy Fox 34 Rhythm 120mm fork turns the Stratos CF2 from a crisp race rocket, to a super versatile bike every rider can benefit from.
  4. Surface 23mm tubeless ready wheels offers a great balance of strength to weight - and is fit for purpose on this machine.
  5. The CF2 can fit one full size and one 500ml water bottle in the main frame (in opposite side entry cages). This makes it perfect for all day outrides.
  6. CF2 is dropper compatible with internal routing. The added weight of the dropper will soon be forgotten after the first drop - go on, do it!
 1X drivetrain mountain bike

1X DRIVETRAIN SPECIFIC DESIGN

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.

 Silverback Stratos CF 2 asymmetry

BOXED ASYMMETRIC TUBE PROFILES

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

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.

IN-TRIANGLE STORAGE BOX CRADLE

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.

 Silverback Stratos CF 2 metric shock

METRIC SHOCK

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

 XC / marathon racing geometry

POP GEOMETRY ADAPTED FOR RACING

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.

 Suspension sag indicator

SAG INDICATOR

Don't leave setup up to chance, line up the rocker notch with the marking on the seatstay to guarantee perfect sag setup.

 carbon support strut

SINGLE SIDED SUPPORT STRUT (REAR SHOCK TO DT)

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.

 Surface carbon mtb wheels

SURFACE CARBON WHEELS

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.

 Silverback Stratos CF 2 carbon layup

TYPE OF CARBON USED AND LAY UP BENEFITS

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.

FAQ.

  • What is the weight limit on this bike?

    120kg - Weight limit will be for combination of bike, rider and kit.

  • Does this bike come with a chainstay protector?

    Yes, but an aditional chainstay protector can be purchased on Speedlab.shop.

  • Would I be able to fit a waterbottle in the front triangle?

    Yes

  • Does this frame support a 140mm rotor?

    Yes, Stratos CF will take a 140mm rotor, allowing for maximum weight saving

  • What maintenance do IGUS bushings require?

    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.

  • What bearings does this frame use?

    Stratos uses headset bearings in the main pivot. These are Token C83-TBT bearings. Contact your local Silverback distributor for more info.

  • How does that suspension work?

    Stratos uses angular contact bearings for the main pivot. This means that as the bearings wear over time it is possible to nip out wear. Headset bearings are simple to disassemble, clean, and regrease, meaning with proper maintenance you shouldn't need to buy replacement bearings every year. All other pivot locations use IGUS bushings for low weight and longevity. Stratos CF uses a flex stay to further reduce weight and maintenance.
