The world's most trusted electronic shifting system. The world's most competitive gravel carbon platform.

For the vast majority of serious gravel riders, Shimano GRX DI2 needs no introduction. Its electronic precision, legendary reliability, and deep compatibility with power meters, cycling computers and third-party components have made it the default electronic standard in performance gravel cycling.

The Rave SLR ID2 in GRX DI2 configuration pairs Shimano's electronic gravel flagship with the premium Miche Graff Aero 48 carbon wheels — a pairing that places aerodynamic performance where it is most impactful — and the Wilier F Bar monocoque carbon cockpit. A complete system: a bike that performs as coherently at race pace as it does over a six-hour all-road day.

Frame & Fork

Carbon Monocoque HUS MOD with Liquid Crystal Polymer. Frame weight 900g (size L). 8.9% aerodynamic drag reduction vs previous model, 5.3W saved at 35 km/h — validated in Wilier's wind tunnel.

Tyre clearance: 52mm with 6mm residual clearance at maximum width. UDH® rear dropout, 1x-only drivetrain architecture, full internal cable routing.

Groupset — Shimano GRX DI2 1×12

Shimano GRX DI2 is the gravel-specific iteration of Shimano's Di2 electronic platform. Synchro Shift intelligence, 12-speed cassette range, hydraulic disc brakes with flat mount. Native integration with Garmin, Wahoo and other head units for real-time gear tracking and automatic shift programming.

Note on gearing: Wilier specifies a fixed cassette ratio and chainring combination for all Rave SLR ID2 builds. Gearing cannot be modified at the time of order.

Wheels — Miche Graff Aero 48, Carbon

Miche Graff Aero 48: premium Italian full-carbon tubeless-ready wheelset, top of the Miche gravel range. 48mm aerodynamic rim profile developed for gravel racing — an increasingly common choice among professional gravel racers seeking aerodynamic gains without the fragility of road-specific carbon wheels.

Cockpit — Wilier F Bar Integrated Handlebar (Monocoque Carbon)

A monocoque carbon cockpit that treats stem and handlebar as a single structural unit. Full internal routing, aerodynamic front-end shaping, 380g — the F Bar is a defining feature of every Rave SLR ID2 build that specifies it. Two configurations are available — 88mm stem with 370mm bar and 114mm stem with 390mm bar. The F Bar's built-in flare increases the effective width at the drops to 400mm and 420mm respectively. Select your configuration before adding to cart.

For riders requiring sizes outside these two standard configurations, the premium F Bar SLR version unlocks additional combinations at an additional cost. Contact us before ordering to confirm availability and pricing.

Computer mount: not included as standard. The F Bar Computer Mount is available separately in our store.

Seatpost

The standard seatpost features 15mm setback. A zero-offset (0mm) version is available at a modest additional cost, selectable before adding to cart.

Crank Length — Size-Specific

Crank arm length is determined by frame size and fixed at the factory: XS 170mm · S 170mm · M 170mm · L 172.5mm · XL 172.5mm · XXL 172.5mm.

If your preferred crank length differs from the factory specification for your size, contact us before ordering to discuss customisation options.
