      The Siablo CF is designed with the focus on Gravel, utilizing a brand new Carbon frame with, the CF is a lightweight bike that exceeds the broad demands put on the gravel category. Designed with current trends and future insight the Siablo CF is an extremely versatile bike, capable of fitting up to 700x50c tyres or 650b road plus should you want the extra comfort. Rack mounts, BB PF30, and hydraulic disc brakes mean that the CF is practical and performs well in all weather conditions.

      DROPPED ASYMMETRIC CHAINSTAY

      The non-drive chainstay has 10% increased area to increase strength and better distribute braking forces.To accommodate a wide range of chainring sizes, the drive side chainstay is dropped to increase clearance. Rectangular chainstay profile tapers down toward the dropout, for absolute stiffness at the bottom bracket, while allowing a degree of dampening at the dropout.

      CARBON USED – TYPE AND BENEFITS

      The structure is mainly composited of T700 UD carbon fibre. Offering equilibrium in stiffness to strength ratio. 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.

    • WHY IT’S BEST.

      1. The flared handlebars means your wrist positioning is more natural, also adding stability and leverage while climbing and descending in the hoods.
      2. The Siablo CF has 6, waterbottle or accessory mounts. Go further on a single fill, or load up and go touring
      3. A Flex Seatstay conceals a degree of road vibration on the dropout side, while being stiff for power delivery at the BB side.
      4. The Flex seatpost adds some comfort, so you can keep going for longer.
      5. The CF is compatible with both 700C large volume tyres and 650B tyres. It is designed to fit a maximum size 700 x 50C and 650B x 2.0” tyre.
      6. Siablo CF is designed for wide chainring compatibility, meaning that you can run what suits your terrain or riding preferences.

      ENGINEERING NOTES.

      CARBON USED – TYPE AND BENEFITS

      The structure is mainly composited of T700 UD carbon fibre. Offering equilibrium in stiffness to strength ratio. 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.

      DI2 COMPATIBILITY AND INTERNAL ROUTING

      All cable routing on the frameset is internal, including the fork. Cables are out of the way, resulting in a sleek look that protects cables from debris ingression. With three cable entry ports, the frame supports the brake hose, rear and front gear cable, or dropper post in 1X configurations. If mechanical shifting is not up to your standard, rest assured that the frame is compatible with Di2 and AXS electronic groupset.

      DROPPED ASYMMETRIC CHAINSTAY

      The non-drive chainstay has increased area to increase strength and better distribute braking forces. To accommodate a wide range of chainring sizes, the drive side chainstay is dropped to increase clearance. Rectangular chainstay profile tapers down toward the dropout, for absolute stiffness at the bottom bracket, while allowing a degree of dampening at the dropout.

      FLARED HANDLEBARS

      The flare on the drop allows for a more natural interface between hand and handlebar. The 16° flare increases clearance between the hoods and wrist, when riding in the drops, allowing for adequate clearance to navigate the bike through demanding terrain.

      GRAVEL FOCUSED GEOMETRY

      The wheelbase of the frameset is semi-short to retain a race 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.

      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 CF.

      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 point for potential failure.

      WHEEL COMPATIBILITY + WHEEL CLEARANCE

      The frameset is compatible with both 700C large volume tyres and 650B tyres.It is designed to fit a maximum size 700 x 50C and 650B x 2.0” tyre. For long distance riding, over moderate to easy terrain; 700C tyres are recommended. While for shorter, demanding terrains, 650B tyres will be the best option.
