Rave SLR SRAM Red XPLR AXS E1 1x13sp

The second-generation Wilier Rave SLR marks a definitive shift in the Italian brand’s gravel program. Moving away from the dual-purpose, all-road compromises of its predecessor, the ID2 generation is a dedicated off-road racing platform. Wilier prioritized outright speed and aerodynamic efficiency, utilizing NACA tube profiles and a broad down tube designed to shield water bottles from the wind.

Beyond aerodynamics, the frame embraces modern gravel racing standards. It is built around a 1x-specific layout with a Universal Derailleur Hanger, maximizing power transfer while drastically increasing tire clearance to 52mm. This singular focus makes the Rave SLR ID2 a highly specialized tool. It lacks the mounting points and internal storage found on adventure-oriented bikes, catering instead to ambitious racers who need a lightweight, highly integrated machine for fast, technical courses.

Fit and geometry

The Rave SLR ID2 utilizes a performance-oriented geometry that balances aerodynamic positioning with the leverage needed for technical off-road handling. With a stack-to-reach ratio of 1.47 on a size large, the fit is decidedly sporty, placing the rider in a low, aggressive posture that stops short of being overly stretched.

Handling dynamics are driven by a compact footprint. Short 421mm chainstays and a tight wheelbase keep the rear wheel tucked in, contributing to the bike’s quick acceleration and nimble cornering. This compact rear center helps the bike feel agile and responsive, counteracting the naturally slower steering that often accompanies high-volume tires.

Fit and control are further shaped by Wilier’s integrated F Bar carbon cockpit. The bar features a narrow profile at the hoods—measuring 390mm on a size large—to minimize frontal area for high-speed efficiency. In the drops, it flares out to 420mm, providing a wider stance and increased leverage for stability when navigating rough descents.

Builds

The Rave SLR ID2 lineup is structured around premium components, with a strong emphasis on modern 1x drivetrains. The build ladder begins with Shimano GRX options, providing a functional entry point to the lightweight carbon frameset.

Moving up the range, the specifications shift to wireless SRAM XPLR groupsets, culminating in the flagship SRAM Red XPLR AXS 1x13 build. These upper-tier models feature Wilier’s integrated F Bar carbon cockpit and roll on deep-section Miche Graff Aero carbon wheels. Across the board, Wilier specifies high-volume Vittoria Terreno tires, ensuring that riders benefit from the frame's expanded clearance right out of the box.

While the frame quality and component integration are high, the value proposition is strictly focused on racing performance rather than utility. The inclusion of a Universal Derailleur Hanger simplifies maintenance and ensures compatibility with direct-mount derailleurs. However, the premium models omit a power meter, requiring serious racers to factor in an immediate aftermarket purchase to complete their setup.

Reviews

Reviewers agree that the Rave SLR ID2 represents a massive improvement in ride quality over the previous generation. By pairing a rigid, lightweight carbon frame with high-volume 50mm tires, Wilier created a bike that "bombs over the rough stuff" (YouTube) without sacrificing its competitive edge. The frame itself remains highly efficient, delivering acceleration that testers describe as "explosive and immediate" (Granfondo), while the wide rubber handles the vibration damping.

Despite the large tires, the bike retains a highly responsive character. Testers noted that the steering feels exceptionally accurate, with the bike feeling "light on its feet" (Granfondo) even on loose terrain. The handling is quick and agile, making evasive maneuvers at high speeds feel natural rather than sluggish.

The primary tradeoff for this performance is a lack of versatility. Reviewers point out that the bike is a pure racing tool, entirely skipping features like down tube storage or fender mounts. Additionally, testers were critical of the flagship spec, noting that the omission of a power meter on a premium race bike feels like a "step back into the analogue era" (Granfondo).
