Wilier Rave SLR ID2 GRX Bike w/Carbon Wheels
Wilier Rave SLR ID2 GRX Bike w/Carbon Wheels Info
The Wilier Rave SLR ID2 GRX Bike w/Carbon Wheels represents a clear statement from one of Italy's most storied cycling brands: gravel racing is serious, and the bikes built for it should be too. Where Wilier's previous Rave SLR attempted to serve both road and off-road riders, the ID2 makes no such compromise. This is a dedicated gravel race machine — engineered from the ground up for the athlete who lines up at the tape and means it. Built in Bassano del Grappa with the same obsessive approach Wilier brings to its WorldTour road platforms, the Rave SLR ID2 treats gravel racing with the same respect the brand has always reserved for the velodrome and the mountain pass.
The aerodynamic case for the ID2 is unusually well-substantiated. Wilier's engineers spent months in the wind tunnel developing new tube profiles that deliver an 8.9% reduction in drag compared to the previous generation — translating to 5.3 watts saved at 35 km/h and more than 50 seconds reclaimed over a 70-kilometer course at 350 watts. The NACA-profiled down tube widens strategically behind the head tube to shield water bottles from oncoming air, while the fork draws inspiration from Wilier's Supersonica SLR road bike — wide stays that accommodate larger tires without sacrificing aerodynamic efficiency. All cabling runs fully integrated through the frame and the proprietary F-Bar cockpit, eliminating every unnecessary surface that would otherwise catch the wind.
At $5,800, this build pairs the SLR carbon frameset with Shimano GRX 1x12 mechanical shifting and Miche Graff Aero 48 carbon wheels — a package that keeps the drivetrain clean and reliable across long hours in variable conditions while delivering carbon wheel speed for race-day efforts. The Vittoria Terreno T50 Mixed tires in 700x50C arrive mounted and ready, matched to the frame's 52mm maximum clearance. That number deserves emphasis: most aerodynamic gravel frames top out well short of 50mm. The Rave SLR ID2 gives you speed without forcing you to compromise on tire volume to get it.

Design Benefits
- Wind-Tunnel-Verified Aerodynamics — The ID2 frame is not marketed as aero; it was proven aero. Wilier published an 8.9% drag reduction over the previous model, with 5.3 watts saved at 35 km/h and 50+ seconds recovered over a 70-kilometer race course at 350 watts. These are the kinds of gains that accumulate across the open, paved connectors between sectors, when you're fighting a crosswind and trying to hold wheels.
- 52mm Tire Clearance on an Aero Platform — Most aerodynamic gravel frames force a tradeoff: go fast or go wide. The Rave SLR ID2 refuses that bargain. Up to 52mm of clearance — 10mm more than the outgoing model — means you can run genuinely capable off-road tires without fighting the frame's limits. The 700x50C Vittoria Terreno T50 Mixed tires included with this build use the full envelope.
- Wilier F-Bar Monocoque Carbon Cockpit — The integrated F-Bar is a full monocoque carbon unit weighing 380 grams, with 390mm across the tops and 420mm in the drops. It's narrow enough for flat-out aerodynamic efficiency on exposed roads, wide enough for confident control when the terrain deteriorates. All cables route internally for a clean front end.
- Miche Graff Aero 48 Carbon Wheels — The 48mm deep carbon wheelset from Miche is built to match the frame's aerodynamic intent. Gravel-specific construction handles the load and vibration demands of off-road racing while keeping the system fast on sustained hard-surface sections. Carbon wheels at this price point, supplied from the factory, add genuine value to this build.
- 1x-Only Architecture with UDH — Wilier designed the ID2 exclusively around 1x drivetrains — no front derailleur provision, full stop. The rear dropout uses the Universal Derailleur Hanger standard, which simplifies hanger replacement in the field and ensures compatibility with current and future gravel-specific groupsets. The frame accepts cassettes up to 52 teeth.
Final Take
The Wilier Rave SLR ID2 GRX is a gravel racer built with a racer's priorities: aerodynamic speed, reliable shifting, and carbon wheel performance in a complete package at $5,800. Wilier made a deliberate choice with the ID2 — they stopped trying to straddle road and gravel and committed fully to off-road race performance. If you're looking for a bike that takes gravel racing as seriously as you do, and you want Italian carbon engineering behind it, the Rave SLR ID2 GRX deserves a close look.
