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