TWH Chronicles: Sarto Raso Gravel — The Marble Edition
Sarto Bikes | Custom Gravel | Bespoke Paint
When gravel riding demands both absolute performance and uncompromising aesthetic brilliance, the Sarto Raso Gravel answers the call. This specific build — the Marble Edition — is a masterclass in Italian custom carbon and bespoke finishing.
Handcrafted in Sarto's Italian workshop, the Raso Gravel takes the aerodynamic and structural innovations of its road sibling and adapts them for the dirt. But it is the paintwork on this specific commission that truly sets it apart: a deep, mesmerizing blue marble effect that must be seen in person to be fully appreciated.
The Marble Finish: A Painter's Masterpiece
Sarto's in-house paint facility is renowned for pushing the boundaries of what is possible on a carbon canvas. The blue marble finish on this Raso Gravel is achieved through a painstaking multi-layer process, creating a sense of depth and texture that mimics polished stone while adding virtually zero weight to the frame.
Contrasting with the deep blue marble are striking copper-gold accents. The Sarto downtube logo, the subtle "raso gravel" insignia on the chainstay, and the beautifully matched titanium bottle cages create a visual warmth that elevates the entire build.
Campagnolo Super Record: The Italian Drivetrain
The component specification matches the ambition of the frame. Campagnolo Super Record wireless provides the shifting precision that a build of this calibre demands — the Italian pairing of Sarto carbon and Campagnolo mechanics is a philosophy as much as a specification.
The Campagnolo brake callipers, machined to a jewellery-like finish, are paired with the 9–42 cassette for a gear range that handles everything from steep mountain climbs to fast gravel descents.
The Wheel System: Campagnolo Bora WTO & Schwalbe G-One RX Pro
Rolling on Campagnolo Bora WTO carbon wheels shod with Schwalbe G-One RX Pro tyres, this build is equally at home on smooth tarmac and loose gravel. The Bora WTO's aerodynamic profile and the G-One's fast-rolling tread pattern create a wheel system that refuses to compromise.
Seamless Integration
Beyond the paint, the Raso Gravel is an engineering marvel. It features fully internal cable routing, maintaining the clean lines expected of a premium aero-gravel platform. The top tube features integrated mounting points, seamlessly blending utility with aesthetics for long days in the saddle.
Every bolt, port, and junction has been considered. The striking blue anodized hardware perfectly complements the marble paint, proving that at The Wheelhouse, we believe no detail is too small when commissioning a custom build.

Start Your BuildOur Relationship with Sarto
The Premier Sarto Dealer in North America
The Wheelhouse is proud to be the premier Sarto dealer in North America. This is not simply a commercial designation — it is the result of years of genuine partnership, deep product knowledge, and a shared belief that a bicycle should be built around the person who rides it.
We sell Sarto across the full range, from the Seta carbon road bikes to the Raso Gravel and beyond. That breadth of experience means our team can speak with authority about the nuances of each model — the way the Raso Gravel's Tri-Composite layup behaves differently from the Seta's carbon compliance, the geometry decisions that make each frame suited to a specific type of rider and terrain. This is knowledge that only comes from building and riding many of them.
Each year, the Wheelhouse team travels to Sarto's headquarters in Castelfranco Veneto, in the heart of the Veneto region of northern Italy. We ride the roads that inspired the frames, run events with the Sarto family, and deepen a relationship that goes well beyond a dealer agreement. The Veneto is cycling country — the Dolomites to the north, the Prosecco hills to the east, and roads that have shaped generations of Italian racing. Riding them with the people who build the bikes changes how you talk about them.
When you commission a Sarto through The Wheelhouse, you are not simply purchasing a bicycle. You are accessing a relationship — with the brand, with the craft, and with a team that has stood in the same workshop where your frame will be built.
The Finishing Details
A Wheelhouse build is considered at every millimetre. The frame and groupset define the machine's character, but it is the finishing kit that reveals the builder's intent. Each component below was chosen deliberately — not from a spec sheet, but from a shared understanding of what this particular bike and this particular rider deserved.
Saddle
Selle Italia Nubuck Special Edition
Hand-finished Nubuck leather with a tactile surface that ages with the rider. The special edition colourway was selected to complement the frame's finish, creating a visual thread from contact point to contact point.
Bar Tape
Matching Custom Wrap
The cockpit is the rider's primary interface with the machine. Matching bar tape to the saddle is not an aesthetic indulgence — it is a commitment to a unified build language that signals craft at every glance.
Bottle Cages
Silca Bourbon Titanium
Silca's Bourbon cages are machined from aerospace-grade titanium, offering the warmth and flex of the material against a carbon frame. A nod to Silca's century of Italian cycling heritage — and proof that even the smallest details are never an afterthought here.
These are the components that transform a high-performance bicycle into a one-of-a-kind commission. Every Wheelhouse build ships with this level of intentionality as standard.
Frequently Asked Questions
What is the Sarto Raso Gravel?
The Sarto Raso Gravel is a bespoke gravel bicycle hand-built by Sarto Cicli in Castelfranco Veneto, Italy. Constructed from Sarto's proprietary Tri-Composite carbon — a blend of high-modulus carbon, Kevlar, and fibreglass — the Raso Gravel is designed for riders who demand road-bike precision on unpaved terrain. Every frame is made to order with custom geometry.
What is the Marble Edition paint finish?
The Marble Edition is a custom paint finish developed exclusively for this Wheelhouse build. The deep blue-teal base is overlaid with a flowing marble-effect pattern in contrasting tones, referencing the natural stone of the Italian Alps. The finish is applied by Sarto's in-house paint team and is entirely unique — no two Marble Edition builds are identical.
What drivetrain is fitted to the Sarto Raso Gravel Marble Edition?
This build is equipped with Campagnolo Super Record AXS, the Italian brand's flagship 13-speed wireless electronic groupset. Paired with Campagnolo Bora WTO carbon wheels and Schwalbe G-One RX Pro tyres, the drivetrain delivers exceptional range and precision across both gravel and tarmac.
What makes the Selle Italia Nubuck saddle a fitting choice for this build?
The Selle Italia Nubuck Special Edition saddle was chosen for its tactile, hand-finished Nubuck leather surface — a material that shares the same artisanal Italian heritage as the Sarto frame itself. The saddle's colourway was matched to the Marble Edition paint, creating a unified visual language from the frame to the contact points.
Can I commission a custom Sarto Raso Gravel through The Wheelhouse?
Yes. The Wheelhouse is an authorised Sarto dealer and builds every Sarto as a bespoke commission. Custom geometry, paint, and component selection are all available. We begin every build with an ID Match fitting to ensure the frame geometry is dialled to your biomechanics before a single tube is cut.
What are Silca Bourbon titanium bottle cages and why are they used?
Silca Bourbon cages are machined from aerospace-grade titanium by Silca — an Italian brand with over a century of cycling heritage. The titanium construction provides a natural flex that protects carbon frame bottle bosses from stress, while the warm metallic finish complements both carbon and custom painted frames. On a build of this calibre, they are the only appropriate choice.
