Super Light Race Carbon Frame

The Carbon Advanced Composite Super Light Race Gravel frame is designed to combine low weight, stiffness, and control. Its direct response enhances acceleration and changes of pace, while the carbon’s shock-absorbing properties help reduce fatigue on rough terrain.

The Carbon Advanced Composite Race Gravel fork provides precise steering and maintains full internal cable routing. The bike features a BB86 bottom bracket, Flat Mount brakes, and thru-axles measuring 12 x 100 mm in the front and 12 x 142 mm in the rear.

Geometry Designed for Fast Gravel

The Silk’s geometry is designed to offer an aerodynamic position without compromising stability. In size M, it combines a 395 mm Reach with a 557 mm stack, promoting a sporty and efficient riding position for Gravel racing.

The 425 mm chainstays provide responsiveness during accelerations, while the head angle is designed to maintain precise and stable handling in fast corners, descents, and on uneven surfaces.

Fully Internal Cable Routing

Cables and hoses are hidden from the handlebars to the inside of the frame, providing a clean front end and reducing exposure to mud, dust, and potential snags. This integration enhances the aesthetics and helps maintain a distraction-free ride, which is especially valued on a competition-oriented bike.

Integrated carbon Cockpit

The Carbon Gravel Racing Handlebar integrates the handlebar and stem into a single carbon structure. This design adds stiffness to the front end, reduces the number of components, and allows the riding position to be adjusted for each frame size.

Cockpit dimensions vary by size:

- XS: 70 mm stem, 360 mm width at the shifters, and 410 mm at the bottom.

- S: 80 mm stem and 360/410 mm width.

- M: 90 mm stem and 360/410 mm width.

- L: 100 mm stem and 380/430 mm width.

- XL: 110 mm stem length and 380/430 mm width.

Shimano GRX Di2 2x12-speed

The Shimano GRX Di2 RX825 electronic drivetrain offers fast, precise, and consistent shifting. Its electronic actuation reduces the effort required to shift gears and maintains stable responsiveness even during intense accelerations or on uneven terrain.

The rear derailleur features Shadow Plus technology, which stabilizes the chain and reduces jolts and movement on rough trails. The GRX Di2 RX825 front derailleur automatically and precisely manages the transition between chainrings.

The Shimano GRX RX610 crankset features 46/30-tooth chainrings, paired with a Shimano HG710 11-36T cassette. This gear ratio provides speed on fast trails and roads, as well as comfortable gear ratios for steep climbs.

Crank length by size: XS: 165 mm; S: 170 mm; M and L: 172.5 mm; XL: 175 mm.

Shimano GRX Hydraulic Brakes

The Shimano GRX RX820 hydraulic brakes deliver power, modulation, and control on surfaces with varying traction. The 160 mm Shimano SM-RT64 rotors provide consistent response on descents, fast corners, and in wet conditions.

The GRX lever’s ergonomic design ensures a secure grip from both the climb grip and the lower part of the handlebars, making it easier to control the bike during technical sections.

Fulcrum Lite GR 2-Way Fit Ready Wheels

The Fulcrum Lite GR wheels are made of aluminum and feature an internal width of 24 mm, providing good support for wide Gravel tires. Their 2-Way Fit Ready technology allows for a Tubeless setup with the appropriate components.

The Fulcrum hubs feature sealed cartridge bearings and 12 x 100 mm thru-axles in the front and 12 x 142 mm thru-axles in the rear. This construction offers reliability and protection against dust, moisture, and heavy use.

Pirelli Cinturato Gravel RC Classic 700 x 45C

The Pirelli Cinturato Gravel RC Classic 700 x 45C tires are designed for gravel racing and offer a balanced combination of speed, traction, and control. Their volume helps absorb bumps and provides stability on loose gravel, dirt, and mixed surfaces. The natural-colored sidewalls add a classic look to the setup, while Tubeless compatibility allows for lower pressures to improve grip and comfort.

Carbon Seatpost and Fizik Saddle

The Megamo Gravel Advanced Carbon seatpost helps reduce the bike’s overall weight and provides controlled flex to filter out some of the vibrations from the terrain. Its length is adjusted for each size: 350 mm for XS and S, 400 mm for M and L, and 450 mm for XL.

The Fizik Vento Argo X5 saddle offers a stable platform to maintain a sporty and efficient riding position during long training sessions and races.
