Rave SLR ID2 SRAM Rival XPLR AXS E1 1x13s (Carbon F Bar)

The Rave SLR ID2 is offered in a wide spread of race-oriented 1x builds, with options from Shimano, SRAM, and Campagnolo. Shimano choices center on mechanical GRX 1x12 and GRX Di2 1x12, while SRAM covers Rival, Force, and Red XPLR AXS E1 1x13. Campagnolo is represented by Super Record X WRL 1x13, including one version with a power meter. Across the range, Wilier keeps the spec strategy tightly aligned with the frame’s purpose: every listed build is 1x, reinforcing the bike’s focus on simplicity, chain security, and modern gravel racing drivetrain standards.

A major differentiator between builds is cockpit specification. Some lower and mid-tier models use the alloy Stemma S2 stem/bar arrangement, while higher-end versions move to Wilier’s carbon F Bar cockpit. That split gives buyers a clear choice between a more conventional alloy front end and a lighter, more integrated carbon setup. The breadth of drivetrain options is also notable: riders can choose between the familiarity of Shimano GRX, the latest wireless SRAM XPLR AXS ecosystem, or Campagnolo’s premium 13-speed gravel group. Even without pricing data, the hierarchy is clear, with Rival and mechanical GRX builds serving as entry points and Red XPLR AXS E1 or Super Record X WRL builds occupying the halo end of the range.

Review coverage has largely reinforced Wilier’s positioning of the Rave SLR ID2 as a highly specialized gravel race bike. BikeRadar, in particular, noted how clearly the frame prioritizes speed and race utility over versatility, pointing to the aerodynamic tube profiles and stripped-back feature set as evidence that this is not intended to be a bikepacking or everyday gravel-allrounder. The absence of down-tube storage and the lack of meaningful provision for mudguards or bags were highlighted as deliberate trade-offs rather than oversights.

That focused approach is likely to appeal to riders who want a fast, modern gravel race machine with current standards such as large tire clearance and a UDH rear end. At the same time, reviewers also make clear that the bike’s narrow brief limits its appeal. Riders looking for a more adaptable gravel bike—something equally suited to commuting, long mixed-surface touring, or utility use—may find the ID2 too single-purpose. The consensus is that Wilier has produced a more coherent and contemporary race-gravel package, but one that gives up practical versatility in exchange for that sharper performance focus.
