Wilier Filante SL Ultegra Di2 Road Bike - 2026 - Bullet Black, S

The Wilier Filante SL Ultegra Di2 Road Bike - 2026 is a lightweight aero road bike that blends race-level speed with improved comfort, using advanced carbon construction and clean integration for efficient performance. It mirrors the aerodynamic design of the Filante SLR while using a revised carbon fibre layup to reduce harshness without adding significant weight. Fully integrated cables and a streamlined cockpit improve airflow and reduce drag, while electronic shifting ensures precise gear changes under load.Key Features and Benefits:Carbon monocoque NHU MOD frame with revised lamination: The frame uses a different carbon fibre layup to reduce stiffness in key areas, which improves vibration damping and lowers rider fatigue over long distances. This results in more stable power delivery and better efficiency on varied road surfacesSLR-derived aerodynamic frame shape: The frame mirrors the proven aerodynamic profile of the Filante SLR, reducing drag at speed. This helps maintain higher speeds with less effort, especially on flat and rolling terrainFully integrated cable system with monocoque cockpit: All cables are routed internally through the frame and handlebar, which reduces air resistance and protects cables from contamination. This leads to cleaner aerodynamics and consistent braking and shifting performanceShimano Ultegra Di2 12-speed groupset: Electronic shifting delivers fast, accurate gear changes with minimal input force. This ensures reliable performance under load and reduces the chance of missed shifts during hard effortsWide tyre clearance up to 30mm: The frame supports wider tyres, which increases grip and improves comfort by allowing lower pressures. This leads to better control and reduced fatigue on rough roadsBalanced race geometry across multiple sizes: The frame is available in a wide size range with race-focused geometry, allowing precise fit. This improves rider position, power transfer, and overall efficiency on long or fast ridesThis bike is built to deliver consistent speed with reduced fatigue across long distances. The revised carbon layup works with wider tyre compatibility to improve comfort without affecting aerodynamic efficiency. The Ultegra Di2 system ensures reliable shifting in all conditions, while the integrated cockpit keeps airflow clean and reduces maintenance points. Each element supports sustained performance with less physical strain.The Filante SL Ultegra Di2 offers a practical balance of speed, comfort, and control for riders who want race-ready performance with added usability. It is well suited to long training rides, fast club runs, and competitive efforts where efficiency matters.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"
