    Force 1x Cyclocross race bike, ready to get dirty.

    Siablo CX Rival is a dedicated cyclocross race bike, proven on the world cup circuit with the OMX Pro team. Featuring an Ultegra groupset, the CX Ultegra is ready to get dirty.

    6061 Hydro formed Alloy frame

    Siablo CX's frame is manufactured from hydro formed, butted 6061 alloy tubing making for a very strong frame. For this kind of application - a CX race bike, a strong aluminium frame is a reliable choice. Hydro forming is a process to shape alloy tubing from the inside, using pressurized water and/or oil into a negative mold cavity resulting in stronger thin wall tubing. The Siablo frame also features two waterbottle mounts in the main triangle and rack and fender mounts so that you can use it for touring or commuting.

    Rival Groupset

    SRAM's Rival is a wallet friendly groupset with top-end features. Single shifter mated to a clutch rear derailleur, means simplicity and a more quiet ride. Also chaindrops and chainsuck are things of the past.

    WHY IT’S BEST.

    1. The CX frame is custom triple butted hydro-formed 6061 alloy. That means the end point wall thickness of the tubes are thicker where they are welded, with the middle wall thickness thinner, making them strong where they need to be, yet resulting in an overall lighter frame.
    2. CX race circuit tested geometry. OMX Pro team rode and tested these bikes during race season, ensuring that it works like it should.
    3. The SRAM Rival groupset is a 1x groupset, making it simplistic, easy to clean, and less likely to produce chainsuck in mucky conditions.
    4. Gone are the days of the loud squeaks whilst maintaining speed. Rim brakes are out and disc brakes are in. And no rim explosions due to excessive brake surface wear.
    5. The Siablo features a durable stylish paintjob with graphics under the clearcoat. This looks great covered in sweat, mud and grass!
    6. In line with Silverback's BIC ethos - this bike is purposefully spec'd and offers unbeatable value.

    ENGINEERING NOTES.

    INTERNATE CABLE ROUTING

    Internal routing on the CX frame keeps the cockpit neat and cables out of harm's way. Also full length housing internal cables have less chance s of dirt ingression, keeping maintenance down.

    DISC BRAKES

    Siablo Rival features SRAM Rival hydraulic disc brakes. Hydraulic disc brakes offer a light lever feel, all-weather performance, great modulation and plenty of stopping power.

    Carbon Fork with 12mm Thru Axle Dropouts

    The Advanced Dynamics Carbon Fork has all-round performance, while retaining absolute functionality. Equipped with fender mounts to protect both rider and components from unwanted debris spray in wet conditions. Fitted with bottle bosses on both stanchions, it greatly increases hydration capacity of the frameset. The bosses also double up as pannier mounts to increase load capacity if you would want to tour or gravel grind on the Siablo CX.

    6061 Hydro formed Alloy frame

    Siablo CX's frame is manufactured from hydro formed, triple butted 6061 alloy tubing making for a very strong frame. For this kind of application - a CX race bike, a strong aluminium frame is a reliable choice. Hydro forming is a process to shape alloy tubing from the inside, using pressurized water and/or oil into a negative mold cavity resulting in stronger thin wall tubing.

    CX race Geometry

    Geometry of the Siablo CX has been fine tuned for the specific needs of CX athletes. Balance, traction, power delivery and great handling are all positively influenced by the geometry.

    THRU AXLES

    Thru-axles effectively bolt the wheel to the frame or fork. By comparison, QR systems only slot in place, and compress the dropout to retain the wheel. The increased strength and stiffness of thru-axles can be attributed to both the increase in effective engagement area and the fixing mechanism to the dropout. The thru-axle system is significantly safer, with fewer points for potential failure.

    Wheels

    Stan's Grail MK3 700c wheels built onto Alex Rims Bear Pawl sealed bearing hubs. This wheelset is burly enough for proper trails and light enough for long trips on your Siablo.
