Wilier has launched an update to its Filante pro-level race bike, ridden by the Groupama-FDJ WorldTour pro team.<\/p>\n

Wilier claims the new Filante ID2 is 13.6% more aero than its predecessor, based on its analyses at the Silverstone wind tunnel in the UK. That\u2019s greater than Wilier had expected based on its CFD modelling, which predicted a 12% improvement in aerodynamics. When it placed a rider atop the bike, it registered a 4.5% aero benefit.<\/p>\n

Wilier says that equates to a 14.15-watt drag reduction at 40km\/h, or a 1 minute, 45 seconds faster time over 70km when riding at 290W.<\/p>\n

\"\"A trip to the Silverstone wind tunnel is becoming an essential for any bike with aero pretentions. <\/p>\n

The brand has also carried out a head-to-head comparison against five WorldTour bikes<\/a>, claiming the new Filante ID2 is 2.42% faster on average.<\/p>\n

Wilier uses a mix of M46JB, T1100 and T800 carbon fibre for the bike\u2019s frame and claims an 860g frame weight, as well as a 7.5% increase in bottom-bracket stiffness over the previous-generation Filante<\/a>. It says a complete bike equipped with Shimano Dura-Ace weighs 7.1kg.<\/p>\n

Aero bottles and cages
\n\"\"Much of the aero gain is claimed to come from the down tube shape, and the aero bottles and cages. <\/p>\n

Wilier says much of the Filante ID2\u2019s aero gain comes from its down tube shape, designed to shield the custom-designed aero bottles and cages, which are a collaboration with Elite<\/a>.<\/p>\n

As with other bikes, such as the Trek Madone Gen 8<\/a>, Wilier says the Filante ID2 is more aero with bottles in place than without, claiming they reduce drag by more than two thirds compared to standard bottles and cages. <\/p>\n

Like the Madone, its system is compatible with regular round bottles as well as its aero bottles, an important consideration for bikes used in races.<\/p>\n

There\u2019s 1,100ml total capacity with the aero bottles in place, or the option to hold a 750ml round bottle on the seat tube to carry more.<\/p>\n

New flared bar
\n\"\"The Filante ID2 follows the Wilier Verticale with its flared bar. <\/p>\n

Wilier adopted front-end integration as long ago as 2016 and the Filante ID2 is fitted with its latest bar\/stem iteration, which it calls the F-Bar ID2. <\/p>\n

As is now common on new performance race bikes, including Wilier’s own Verticale<\/a>, there\u2019s a flare to the bar \u2013 in this case, 3 degrees. Wilier has three widths available: 350\/380mm, 370\/400mm and 390\/420mm. Effective stem lengths run from 75mm to 120mm.<\/p>\n

The new handlebar completely encloses the clamping hardware, protecting it from contamination.\u00a0<\/p>\n

Wilier has also borrowed the aero, vibration-absorbing seatpost profile from its Supersonica SLR time trial bike. It comes stock in 0mm setback, but you can request a 15mm-setback version when ordering.\u00a0<\/p>\n

As is increasingly the case with modern road bike designs, including the Specialized Tarmac SL8<\/a> and the Cannondale SuperSix Evo<\/a>, there\u2019s not enough room in the seatpost to fit a Shimano Di2 battery, so Wilier has moved it to the bottom bracket area, where it\u2019s housed in a resin casing. It can be removed easily if needed. <\/p>\n

Wilier says the placement also lowers the bike’s centre of mass, improving high-speed stability.<\/p>\n

Updated fork and seatstay profiles
\n\"\"Wilier says the seatstays are angled in slightly for better airflow. <\/p>\n

Wilier has worked on its fork design, with a new aero blade profile, a more robust fork crown for increased torsional stiffness, an aero fin on the left leg that helps improve aerodynamics around the brake caliper and rotor, and a blind thru-axle bolt on the right leg to smooth airflow.<\/p>\n

There\u2019s been more work done on the rear triangle, which now offers 34mm tyre clearance and a UDH dropout<\/a>, with a slightly increased 41.1cm chainstay length. The seastays are now angled slightly inwards, with the 2.5-degree angle claimed to improve aerodynamic interaction between the stays and the rider\u2019s legs.<\/p>\n

Along with the Universal Derailleur Hanger<\/a> at the rear, the front derailleur hanger can be removed, so the Filante ID2 is compatible with SRAM Full Mount 1×13-speed groupsets<\/a> or a 56-tooth single chainring.<\/p>\n

Wilier Filante ID2 specs and prices
\n\"\"Royal blue is one of five colour options. <\/p>\n

Wilier will sell the Filante ID2 equipped with a range of top-tier groupsets, including options with and without a power meter<\/a>. <\/p>\n

There are two wheelset options: the higher-spec 1,445g Miche Kleos RD 50<\/a> and the lower-spec Kleos 50 with a 1,545g claimed weight. There\u2019s also a frame-kit option, complete with bar\/stem, and aero bottles and cages.<\/p>\n

There are six frame sizes available, which in combination with the different component choices and setups offer 420 different sizing options. The Filante ID2 is available in five colours.<\/p>\n
