The Wilier Verticale SLR
Lighter Than Light
Wilier Triestina: Built to Climb
Wilier Triestina has been building bikes in the Veneto region of Italy since 1906 — over a century of racing heritage distilled into carbon and ambition. The Verticale SLR is their lightest frame ever, and it replaces the Zero SLR with a single-minded goal: shed every unnecessary gram without giving up the stiffness and precision that make a bike feel fast under load.
This isn't lightweight for the sake of a number on a scale. It's lightweight you feel on the first steep ramp — and every one after it.
The Pursuit of Controlled Lightness
Making a light frame is relatively simple. Making a light frame that's also stiff, precise, and durable — that's the real engineering challenge. Wilier's approach with the Verticale SLR starts at 648 grams for a size M frame and a 296-gram fork, but those numbers only matter because the ride quality backs them up.
This is a bike that responds the instant you stand on the pedals, holds its line through fast descents, and doesn't punish you on rough roads.
Where Grams Become Speed
The complete frame kit — frame, fork, seatpost, handlebar, headset, thru axles — comes in at a stated 1,623 grams. That's 9.7% lighter than the disc-brake Zero SLR it replaces. In real-world terms, you feel that difference the moment the road tilts upward. Acceleration is more immediate, rhythm is easier to hold, and the bike simply disappears beneath you when the gradient bites.
But lightness alone doesn't win races. Wilier tuned the Verticale SLR for stiffness where it matters — at the bottom bracket for sprinting, through the head tube for confident handling — so nothing gets lost when you put the power down.
Italian Craft in Every Detail
The Verticale SLR carries that unmistakable Italian design sensibility — clean lines, purposeful shapes, and a presence that says "race bike" without shouting it. Every tube profile, every junction, every surface finish is considered.
It's the kind of bike that looks fast standing still, and faster once it's moving.
Toray Carbon: T800 + T1100 + M46JB
Three grades of Toray carbon fiber — T800, T1100, and M46JB — are cut into over 400 individual pieces and laid up using Wilier's Active Moulding process. Foam polymer molds adapt to the material during curing, eliminating excess resin and weight while maintaining the structural integrity the frame needs to perform under race loads.
Engineering Every Advantage
The carbon monocoque V Bar weighs approximately 310 grams and comes in 6 sizes. A subtle flare at the hoods positions your arms 30mm closer together than at the drops — better aero without sacrificing control.
The 296-gram fork features a twisted brake-side leg that optimizes the carbon layup for braking forces. Both legs use Kammtail profiling — a truncated aerofoil shape — for cleaner airflow. All with a consistent 46mm offset across every size.
At 152 grams with two setback options — 0° and -15° — the seatpost includes an integrated rear light and race number holder. The new clamp tightens diagonally from beneath the top tube for a cleaner, more aerodynamic profile.
The rear dropout features a new outline designed to improve both aerodynamic flow and structural rigidity through the rear triangle. Cleaner routing, less drag, and a stiffer connection to the rear wheel.
Anodized AL 7075-T6 thru axles from Miche — lighter hardware that tucks in tighter to reduce drag and keep the lines clean. Less material in the wind, no compromise on security.
The V Bar: 310 Grams of Purpose
Wilier designed the V Bar from scratch as a carbon monocoque cockpit — not a retrofit from another model. It comes in 6 sizes to match the frame, with stem lengths from 90mm to 150mm and widths of 37/40mm or 39/42mm. The subtle flare at the hood position narrows your frontal profile by 30mm compared to the drops, giving you a real aero advantage on flat roads and descents without changing your grip.
Asymmetrical Fork: Form Follows Function
The fork is where Wilier got creative. The brake-side leg has a twisted carbon layup — thicker where braking forces demand it, thinner where they don't. Both legs feature Kammtail profiling for improved airflow, and the fork uses a single 46mm offset across all six sizes. At 296 grams, it's 24 grams lighter than the Zero SLR fork, but the real gain is in how it handles: planted under braking, precise through fast corners.
Active Moulding: Precision at the Layup
Wilier's Active Moulding process uses foam polymer molds that adapt to the carbon during curing — pressing out excess resin without crushing the fibers. The result is a frame built from 400+ individually cut carbon pieces that weighs 648 grams in a size M, with a stiffness-to-weight ratio that Wilier says outperforms the Zero SLR across the board. This isn't just a lighter bike — it's a better-built one.
New Racing Geometries
The Verticale SLR isn't a carbon copy of the Zero SLR with less weight. Wilier reworked the geometry — optimizing reach for climbing ability and sportiveness while keeping the stack nearly unchanged. Smaller sizes got a slightly shorter reach for better handling on steep gradients; larger sizes got a slightly longer reach for stability at speed. The result is a bike that fits more riders, more naturally.
Integrated Cyclocomputer Mount
A purpose-designed mount sits flush with the V Bar, saving weight over aftermarket solutions and keeping the cockpit clean. Compatible with Garmin and Wahoo units.
Brake Sheath Routing
Wilier reworked the upper grip area to improve brake cable routing — smoother lines, less friction, and a cleaner look where the bars meet the stem. Small detail, real impact on feel.
Direct-Mount Front Derailleur
The Verticale SLR uses a new direct-mount front derailleur coupling — purpose-built for this frame. It's lighter, stiffer, and more precise than the bolt-on systems it replaces.
32mm Tire Clearance
Room for up to 32mm tires means you can run the Verticale SLR on rough roads, gravel transitions, or just benefit from the lower rolling resistance and better comfort of wider rubber on your everyday rides.
Find Your Size
The Verticale SLR comes in six sizes — XS through XXL — with geometry tuned specifically for climbing performance and all-around racing. A few millimeters of reach or a degree of head tube angle can transform how a bike handles on steep gradients versus open flats.
