TECH HIGHLIGHTS


MY24_Siablo_CF_carbon_shape

INTERNAL CABLE ROUTING & DI2/AXS READY

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.

MY24_Siablo_CF_carbon_shape

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.

MY24_Siablo_CF_carbon_shape

SBC CARBON 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.

MY24_Siablo_CF_carbon_shape

DROPPER POST INCLUDED

The SE:SERIES GR CF includes a dropper seatpost with 100mm of travel. The dropper post cable is routed internally through the frame, with a multi-position remote lever on the handlebars.

MY24_Siablo_CF_carbon_shape

WIDE TYRE 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.


MY24_Siablo_CF_carbon_shape

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 SE:SERIES GR CF is super capable and wants to be challenged.

MY24_Siablo_CF_carbon_shape

FORK RACK MOUNTS

Pannier mounts on the fork let you carry extra gear up front, improving load balance and boosting the bike’s bikepacking and touring capability without hurting handling. (Rack not included)

MY24_Siablo_CF_carbon_shape

REAR RACK MOUNTS

Rear rack mounts make a gravel bike far more versatile — they let you carry real gear on a fast, off‑road‑ready frame, turning it into a capable commuter, tourer, or bikepacking rig without compromising performance. (Rack not included)

MY24_Siablo_CF_chainstay

HYDRAULIC DISC BRAKES

SE:SERIES GR CF features hydraulic disc brakes. Disc brakes offer all-weather performance, great modulation

MY21-Siablo_CF-Handlebars

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.

MY24_Siablo_CF_thruaxle

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.
