Wilier Filante SL ID2 Ultegra Di2 Bike Info
The Wilier Filante SL ID2 Ultegra Di2 Bike is an aero road bike for riders who want the shape and race-ready position of Wilier's flagship Filante at a more approachable price. Wilier has been building bikes in Bassano del Grappa, Italy, since 1906, and the Filante is the line the brand aims at the fastest end of road racing. The SL ID2 takes its silhouette and much of its technology from the top-tier Filante SLR ID2, then pairs it with a build meant for real riding rather than a spec-sheet arms race.
The frame and fork are carbon monocoque construction, with every cable routed internally through the R-Bar integrated cockpit. That one-piece carbon bar and stem is new to the SL this generation. Wilier designed the R-Bar with about 3 cm of flare between the tops and the drops, so your hands sit wider in the drops for control without pushing the brake levers outward. The position underneath stays compact and forward-leaning, in line with the SLR's racing geometry. This isn't a relaxed endurance bike, and it doesn't try to be. It's built for sitting low, putting your head down, and holding speed.
Shifting and braking come from Shimano's Ultegra Di2 R8150 group, a 12-speed electronic system with a 50/34 crankset and an 11-30 cassette. If you've ridden Ultegra Di2 before, you know what to expect: fast, consistent shifts and a familiar two-chainring layout with gearing that suits rolling terrain, fast group rides, and sustained climbs. Hydraulic Ultegra R8170 disc brakes handle stopping, with 160mm rotors up front and 140mm in the rear. The frame has a UDH derailleur hanger and a removable front derailleur mount, which keeps it flexible if you later change drivetrain setups.
Tire clearance is one of the more practical updates on this generation. Wilier lists room for tires up to 34mm, up from 30mm on the previous Filante SL, and the bike ships with Vittoria Rubino V tires in a 700x30 size. That extra volume matters on rough pavement, mixed-surface detours, and long days where comfort decides how strong you feel at the end. It also means you can run wider rubber if your roads call for it, which makes this aero frame less of a one-trick race machine.
The Vision SC45 i23 carbon wheels match the frame's aero intent and give the bike a deep-section look from the first ride. They're a reasonable place to start, and if you later want to trim weight or sharpen acceleration, wheels are the logical upgrade. A Selle San Marco Shortfit 2.0 open-fit saddle comes fitted, and a Filante carbon seatpost with a -15mm offset rounds out the contact points. Pedals are not included, so you'll choose your own.
The Filante SL ID2 is offered in six sizes, XS through XXL, so riders from compact to tall can find a fit. Wilier also offers an optional Aerokit SL that integrates bottles and holders into the frame, using standard round bottles rather than the flattened ones on the SLR. If you want an aero road bike with Shimano Ultegra Di2, wide tire clearance, and the lines of Wilier's top Filante, this is the build to look at.
