Wilier Triestina has been building racing bicycles in Bassano del Grappa, Italy since 1906 — a lineage that spans the golden age of European road racing and carries through to bikes like this one. The Wilier Filante SLR ID2 Red AXS Bike is the brand’s flagship aero road platform, built from HUS MOD+ Crystal Liquid Polymer carbon and equipped throughout with SRAM Red AXS E1 — their current top-tier wireless electronic groupset. “Filante” means streamlined in Italian, and the name is accurate: this is a bike engineered from first principles around aerodynamic speed, refined through the ID2 evolution of Wilier’s integrated design language.

The frame and fork share the same HUS MOD+ Crystal Liquid Polymer carbon specification — Wilier’s highest-performing material designation, combining premium fiber selection with a liquid polymer resin system that manages the stiffness, weight, and compliance balance the aero road racing category demands. Tube profiles and junctions are shaped for aerodynamic efficiency, with fully internal cable routing that keeps the frame’s surface uninterrupted from head tube to dropout.

The cockpit is the F-Bar ID2 — Filante Bar, Integrated Design, second generation. This is a single carbon unit combining stem and handlebar, built with a dedicated computer mount for Garmin or Wahoo heads and fully compatible with the internal cable routing architecture of the frame. Integration at the front end means no exposed cables, no stem clamp interface to manage, and a front profile that the wind sees as one coherent shape. The F-Bar ID2 was designed for this bike, not adapted from a road component.

The SRAM Red AXS E1 drivetrain runs through every contact point. Shifters, front derailleur, rear derailleur, calipers, and crankset are all Red AXS E1 — SRAM’s flagship tier, wireless throughout. The crankset includes an integrated power meter, making this a data-ready race build from the first ride. Chainrings are 48/35, running against a SRAM Red XG-1290 E1 cassette in 10-36 12-speed — a range that handles flat racing and genuine climbing. Brakes are SRAM Paceline X 160mm rotors front and rear.

The wheels are Miche Kleos 50 carbon clinchers — a 50mm deep Italian carbon wheelset running CeramicSpeed bearings in both hubs. Ceramic bearings produce measurably lower rolling resistance than steel alternatives at race effort levels. Tires are Vittoria Corsa Pro 700x28 — one of the fastest road tires currently available, tubeless-compatible. The frame accepts up to 700x34 for riders who want additional versatility.

Design Benefits

1. HUS MOD+ Crystal Liquid Polymer carbon — Wilier’s top-tier material specification combines premium carbon fiber with a liquid polymer resin system for the stiffness-to-weight ratio and compliance balance that defines a competitive aero road bike. Frame and fork are built to the same specification, ensuring consistent behavior front to rear.
2. F-Bar ID2 integrated cockpit — The second-generation Filante Bar is a single carbon unit designed for this frame, with internal cable routing and a dedicated Garmin/Wahoo computer mount. Integration eliminates the mechanical and aerodynamic compromises of assembled cockpits.
3. Full SRAM Red AXS E1 with power meter — Every drivetrain contact point is Red AXS E1 — SRAM’s highest wireless tier. The included power meter means this bike is data-ready without additional cost or installation. The 48/35 / 10-36 combination covers race gearing with sufficient climbing range.
4. Miche Kleos 50 with CeramicSpeed bearings — A 50mm Italian carbon wheelset with CeramicSpeed ceramic bearings in both hubs. Ceramic bearings produce measurably lower friction than steel at race effort levels, a benefit that compounds over hours of riding. The 50mm depth provides meaningful aero advantage on flat and rolling terrain.
5. Vittoria Corsa Pro 700x28 tires — Among the fastest road tires available. The Corsa Pro’s graphene-enhanced compound makes it appropriate for race day, and the 28mm width provides comfort and grip without aerodynamic penalty. Tubeless-compatible.
6. Six sizes, six colors — XS to XXL covers a broader range than most aero road bikes at this price. Six colors — Firelight Red, Solar Bronze, Lunar Grey, Eclipse Black, Pure White, and Aurora Blue — reflect Wilier’s Italian attention to visual identity.

Final Take

The Wilier Filante SLR ID2 Red AXS Bike is a complete race build from a brand that has been competing at the highest level of European road racing for over a century. HUS MOD+ carbon, fully integrated ID2 cockpit, SRAM Red AXS E1 with power meter, CeramicSpeed-equipped Miche Kleos 50 wheels, and Vittoria Corsa Pro tires — there is nothing on this bike that needs upgrading before race day. For the rider who wants a fast Italian aero bike with the equipment to match, the Filante SLR ID2 delivers the complete picture.
