The Wilier Filante SL 105 Di2 SWR Road Bike - 2026 is a lightweight carbon road bike that combines race-level aerodynamics with improved comfort for sustained performance over long distances. It carries the same aerodynamic frame shape as the Filante SLR, paired with a revised carbon layup that reduces harshness without adding significant weight. Fully integrated cables and a clean cockpit improve airflow and reduce drag, while Shimano 105 Di2 electronic shifting delivers consistent gear changes under load.Key Features and Benefits:SLR-inspired aerodynamic frame design: The frame uses the same shapes developed for the Filante SLR, refined in the wind tunnel to reduce drag across the full bike. This improves efficiency at speed, helping you maintain momentum with less energy output over long efforts and high-speed riding.Revised carbon fibre lamination: The frame uses a different composite layup to reduce stiffness in key areas while keeping overall strength high. This absorbs more road vibration, reducing fatigue and allowing you to sustain power for longer without discomfort.Lightweight carbon monocoque construction: Built using Carbon Monocoque NHU MOD, the frame keeps weight to around 1010g while maintaining structural rigidity. This supports efficient power transfer and responsive handling when accelerating or climbing.Fully integrated cable routing and cockpit: Cables are routed internally through the frame and cockpit using a monocoque handlebar system. This reduces aerodynamic drag and protects cables from external elements, resulting in smoother airflow and lower maintenance needs.Shimano 105 Di2 12-speed electronic groupset: The electronic drivetrain provides precise, consistent gear changes in all conditions. This improves shifting accuracy under load and reduces the need for manual adjustment, supporting reliable performance on varied terrain.Clearance for up to 30mm tyres: The frame allows wider tyres for improved grip and vibration damping. This increases comfort on rougher roads while maintaining speed and control, making the bike suitable for both racing and long-distance riding.This bike supports consistent speed and reduced fatigue across long rides and demanding routes. The aerodynamic frame limits wasted energy at higher speeds, while the revised carbon structure reduces road vibration that can affect endurance. Shimano 105 Di2 ensures accurate shifting without hesitation, and the integrated cockpit keeps the front end clean and efficient. Together, these features create a balanced setup that maintains performance without compromising comfort.This is a strong choice if you want a fast road bike that remains efficient over longer distances. Its aerodynamic efficiency, controlled ride feel, and reliable electronic shifting make it well suited to consistent training and racing use.Size Guide:XXS (44): 4'8"-5'1"XS (48): 5'1"-5'4"S (51): 5'4"-5'7"M (54): 5'7"-5'10"L (56): 5'10"-6'0"XL (58): 6'0"-6'3"XXL (60): 6'3"-6'5"XXXL (62): 6'5"-6'9"
