      • A SUPER VERSATILE ALLOY GRAVEL BIKE.

        The Siablo GRX has been designed from the ground up as a gravel bike, utilizing a different frame to the Siablo CF, the GRX exceeds the broad demands put on the gravel category. Designed with current trends and future insight the Siablo GR is an extremely versatile bike, capable of fitting up to 700x45c tyres or 650b road plus should you want the extra comfort. Rack mounts, threaded BB, and mechanical disc brakes mean that the Siablo GRX is practical and easy to service with basic tools.

        HYDROFORMED BUTTED ALLOY FRAME

        Siablo GRX's frame is manufactured from hydro formed, butted 6061 alloy tubing making for a very strong frame. For this kind of application - a gravel frame, 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.

        SBC FORK

        The SBC 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 of the Siablo GRX.

      • WHY IT’S BEST.

        1. Siablo GRX is designed to require minimal maintenance, and features reliable, quality components and tubeless ready wheels. No one wants to be stranded on an adventure.
        2. The GRX frame has space for 2 full oversized water bottles inside the frame.
        3. The compact frame is nimble, even though the geometry is very comfortable on long rides.
        4. The lightweight SBC carbon fork has an integrated fender mounting hole, as well as 2 more water bottle or accessory mounts.
        5. Cable disc brakes are easy to adjust and maintain, and works well in all weather and terrain conditions.

        ENGINEERING NOTES.

        ALLOY GRX FRAME

        Siablo GRX is a stand alone gravel focused frame with unique geometry. The frame is designed to deal with the demands of the modern gravel enthusiast.

        GRAVEL FOCUSED GEOMETRY

        The wheelbase of the frameset is semi-short to retain a trail capable bike, with good weight distribution under load. A slack head angle makes for a terrain capable front end that will roll challenging obstructions. The steeper seat angle aids in ascending more efficiently, with better power transfer at variable gradient increase. The GR is super capable and wants to be challenged.

        INTERNAL ROUTING

        Internal routing 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.

        THRU AXLE DROPOUTS

        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.

        SBC FORK

        The SBC 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 of the Siablo GRX.

        DISC BRAKES

        Siablo GRX features mechanical cable actuated disc brakes. Disc brakes offer all-weather performance, great modulation
