Wilier Filante SLR ID2 Force AXS Bike w/Power Meter
Wilier Filante SLR ID2 Force AXS Bike w/Power Meter Info
The Wilier Filante SLR ID2 Force AXS Bike w/Power Meter is Wilier's flagship aero road bike — not a derivative of a WorldTour platform, but the platform itself. Developed hand-in-hand with the Groupama-FDJ United Cycling Team, the Filante SLR ID2 is what professional riders use when the goal is pure speed. At $12,300, this build puts that machine in your hands with a factory power meter, a SRAM Force AXS wireless drivetrain, and a complete race-day setup that requires nothing further before the start line.
The ID2 represents a second-generation evolution of the SLR — and the improvements are specific, measured, and meaningful. The Crystal Liquid Polymer carbon frame holds the same 860-gram weight as the first generation (painted, size M), but bottom bracket stiffness increased by 7.49% to 201 Nm/°, delivering more direct power transfer at every pedal stroke. The aerodynamic gains are where the ID2 makes its clearest argument: a 13.1% reduction in CdA for the bike alone at 50km/h, a 5.22% reduction with rider at 0° yaw, and a 5.04% improvement at 15° yaw — the kind of real-world crosswind angle that matters in a race. Translated to effort, the ID2 requires 273.8 watts to maintain 40km/h, down from 287.95W on the ID1. Over 70 kilometers at 290 watts, the ID2 saves 1 minute and 45 seconds. These numbers came from Wilier's development work with professional riders, not a controlled lab scenario designed to produce favorable marketing copy.
The F-Bar ID2 cockpit is specific to this generation of the SLR. It's a one-piece integrated carbon bar and stem with fully internal cable routing — standard for the Filante family — but the ID2 adds a built-in computer mount compatible with Garmin and Wahoo head units. No adapter, no aftermarket bracket disrupting the front end. The data-focused rider has a clean, integrated setup out of the box. The seatpost runs a 0mm offset, positioning this firmly as a race bike with a race fit rather than the -15mm setback of the Filante SL builds. The SRAM Force AXS E1 crankset ships with a power meter integrated, so structured training with accurate wattage data begins immediately — no separate purchase, no installation appointment.
The rest of the build reflects the SLR's position at the top of the Filante lineup. Miche Kleos 50 carbon wheels replace the SWR EVO 50 found on the SL builds — a step up in quality and refinement at the same 50mm depth. Vittoria Corsa Pro 700x28c tires are one of the best clincher race tires available, significantly faster rolling than the Rubino spec on the SL. The frame accepts tires up to 34mm — wider clearance than the SL — and ships with an included aero bottle cage kit. Six color options are available, with Firelight Red, Solar Bronze, Pure White, and Aurora Blue carrying a premium paint surcharge reflected in the $12,300–$13,300 price range.
Design Benefits
- WorldTour aerodynamics with quantified improvements over the first generation. The ID2 reduces bike-only CdA by 13.1% at 50km/h compared to the original SLR, with a 5.22% reduction with rider at 0° yaw. At 40km/h, it requires 14.15 fewer watts than its predecessor — and saves 1 minute 45 seconds over 70km at 290W. These gains were developed and validated by Groupama-FDJ United at the race level.
- Crystal Liquid Polymer carbon — lighter and stiffer than the Filante SL. The 860g frame is 150g lighter than the SL's 1,010g, with bottom bracket stiffness of 201 Nm/° — 7.49% stiffer than the first-generation SLR. More power reaches the rear wheel with less frame flex under hard accelerations and sprints.
- F-Bar ID2 cockpit with integrated computer mount. The ID2-specific one-piece carbon cockpit routes all cables internally and includes a native Garmin/Wahoo mount — no adapter bracket, no afterthought hardware on the front of the bike. A clean aero front end with the head unit exactly where it belongs.
- Factory power meter — no additional purchase required. The SRAM Force AXS E1 crankset ships with an integrated power meter. Accurate wattage data from day one, fully compatible with the AXS app and any ANT+/Bluetooth head unit.
- Premium race build throughout. Miche Kleos 50 carbon wheels, Vittoria Corsa Pro tires, Prologi Nago R4 saddle, and an included aero bottle cage kit. The SLR ID2 ships ready for race day in every detail.
Final Take
The Wilier Filante SLR ID2 Force AXS is the bike Groupama-FDJ United races. The ID2 generation delivered real, measurable aerodynamic improvements over the original — not incremental refinements, but a 13.1% reduction in frontal drag for the bike alone and nearly two minutes saved over a 70km effort. Paired with a factory power meter crankset, a cockpit designed for a computer mount, and a premium race build from tires to saddle, this is a complete, data-ready aero road bike for riders who take the sport seriously. The Force AXS groupset is the only thing separating this from a Red-spec build — and the frame, wheels, and cockpit are identical regardless of which you choose.
