The Wilier Filante SL ID2 Ultegra Di2 is an aerodynamic carbon road bike developed for riders who want responsive handling and efficient performance on the road. Drawing on the design of the Filante SLR ID2, it combines race-focused geometry with integrated components and modern features, making it suitable for racing, fast club rides and longer training sessions.

The Filante SL ID2 features a carbon monocoque frame designed around aerodynamic efficiency and responsive handling. Developed using the same design approach as the Filante SLR ID2, with input from the Groupama-FDJ United technical team, it considers aerodynamics across the complete bike and rider rather than focusing solely on the frame.

Its race-focused geometry is shared with the Filante SLR ID2, providing precise steering through corners and stability when riding at speed. The frame is designed to respond efficiently to changes in pace, whether accelerating out of corners, climbing or maintaining speed on flatter roads.

A matching Filante SL ID2 carbon fork complements the frame, providing a lightweight and responsive front end. Both the frame and fork use 12mm thru-axles for secure wheel attachment, while fully integrated cable routing creates a clean appearance and reduces exposed cables.

Despite its racing focus, the Filante SL ID2 offers practical versatility. Tyre clearance of up to 34mm allows riders to fit wider tyres for additional comfort and grip on rougher roads. The frame also supports SRAM's Universal Derailleur Hanger (UDH) standard and is compatible with single-chainring drivetrains, providing additional options for future component choices.

Shimano Ultegra Di2 provides the bike's 12-speed electronic shifting. The system delivers precise, consistent gear changes at the press of a button, making it easier to select the right gear when accelerating, climbing or riding at speed.

The Ultegra chainset is paired with a Shimano 105 12-speed cassette and KMC 12X chain, providing a practical combination of components for regular training and competitive riding. Electronic shifting also reduces the need for traditional gear cable adjustments, helping maintain consistent shifting performance.

Shimano Ultegra hydraulic disc brakes provide controlled stopping power in changing conditions. A 160mm front rotor and 140mm rear rotor offer a balance of braking performance and weight, while Shimano's Ice-Tech rotor technology helps manage heat during sustained braking.

The Filante SL ID2 rolls on Miche SWR Evo 50 wheels, featuring a 50mm rim profile designed with aerodynamic road performance in mind. The deeper rims are intended to help reduce aerodynamic drag, particularly when maintaining speed on flatter roads and faster sections.

Schwalbe One Performance TLE folding tyres provide a balance of rolling efficiency, grip and durability for road riding. Their tubeless-ready construction also allows riders to use a compatible tubeless setup, which can help reduce punctures and provide greater flexibility when adjusting tyre pressures.

One of the Filante SL ID2's standout features is the Wilier R-Bar integrated cockpit. Developed to balance aerodynamics and ergonomics, it features fully integrated cable routing and a flared drop design that increases handlebar width by 30mm at the drops.

This provides additional leverage and control when descending or cornering, while maintaining a narrower position at the brake hoods. The design allows riders to adopt a more aerodynamic position without sacrificing the stability offered by wider drops.

Handlebar dimensions vary by frame size, with integrated stem lengths of 90mm, 100mm and 110mm across the specified sizes. This helps maintain a suitable cockpit fit while preserving the bike's integrated appearance.

A Filante-specific carbon seatpost features a 15mm setback, contributing to the bike's streamlined design while allowing saddle position adjustment. The Prologo Dimension RS saddle completes the contact points, offering a compact design suited to performance-focused road cycling.

The frame also features a fully integrated headset with slim bearings and a Miche Integrale BB86 bottom bracket, contributing to the bike's clean construction and integrated design.

With its aerodynamic carbon frame, Shimano Ultegra Di2 electronic shifting and Miche SWR Evo 50 wheels, the Wilier Filante SL ID2 is designed for riders who prioritise speed and responsive handling. Its 34mm tyre clearance and adaptable frame design also provide useful versatility for training and longer road rides.

Specification note: The supplied specification doesn't confirm the chainring sizes, cassette range or fitted tyre width, so I've avoided adding those details. The manufacturer confirms clearance for tyres up to 34mm, but this shouldn't be confused with the width of the tyres supplied.

The specification also identifies Shimano Ultegra Di2 shifters and chainset, but doesn't list the front or rear derailleurs individually. I've therefore described the drivetrain as Ultegra Di2 without assigning specific derailleur model numbers.

Occasionally, without notice, manufacturers change product design and/or specifications.
