Wilier Filante SLR ID2 Super Record WRL 13 Bike Info

The Wilier Filante SLR ID2 Super Record WRL 13 Bike is Wilier's flagship aero road bike, built with Campagnolo's top wireless groupset. Wilier has been building bikes in Italy since 1906, and the Filante is the line it builds for fast group rides, road races, and the kind of windy, high-speed days where aerodynamics decide who is still on the front. This version of the Filante SLR is the second generation, and Wilier says it saves about 14 watts at 40 km/h compared with the previous Filante. That figure comes from Wilier's own testing, so treat it as a reference point, not a promise.

An Aero Frame Built Around Integration

The frame and fork are carbon monocoque, made with Wilier's HUS MOD+ carbon and Crystal Liquid Polymer. Cable routing is fully internal, and the headset uses Wilier's custom superslim bearings, which keep the front end narrow and clean. The 0 mm setback Filante SLR carbon seatpost is a custom shape that matches the frame. Max tire clearance is 700x34, and the bike ships on Vittoria Corsa Pro 700x28 tires, so there is room for wider rubber on rougher roads.

Geometry is race-oriented. Head angles run from 70.6 degrees on the XS to 73.5 degrees on the XXL, and head tube length grows from 99 mm to 183 mm across six sizes. A size M has a 541 mm stack and a 386.5 mm reach, which puts you in a low, forward position without being extreme. Chainstays are 411 mm on XS through L and 413 mm on XL and XXL.

The Cockpit

The F-Bar ID2 is an integrated carbon bar and stem with a built-in Garmin and Wahoo computer mount. It gives the front of the bike a tidy shape, and it hides the hoses and wires that would otherwise sit in the wind. The tradeoff is adjustability. You can't swap stems to fine-tune reach, so size selection matters more than on a bike with a conventional bar and stem. If you are between sizes, a fitting before you buy is worth the time.

Campagnolo Super Record Wireless

The groupset is Campagnolo Super Record WRL 13, with wireless shifting, 13 speeds, and hydraulic disc brakes. It comes with a 50/34 crankset, a 10-33 cassette, and 160 mm Campagnolo 03 rotors. A 10-33 cassette with a 34-tooth small ring gives a wide gear range for a race bike, so the climbs on a typical club ride are well covered. The bottom bracket is Campagnolo's QCK-Tech Pressfit.

Wireless shifting removes the shift cables from the cockpit and frame, which is part of why the Filante's integrated front end can be so clean. If you ride Campagnolo for its feel and finish, this is the version of the Filante built to showcase it.

Wheels and Contact Points

The wheels are Miche Kleos RD 50 carbon with CeramicSpeed bearings. The 50 mm depth is a sensible match for a bike like this, deep enough to add aero benefit and moderate enough to stay manageable in gusty conditions. The saddle is a Prologo Nago R4 PAS Tirox with a 137 mm width. Pedals are not included, so you can choose the system you already ride.

Colors and Fit

The Filante SLR ID2 comes in six colors: Eclipse Black, Pure White, Aurora Blue, Firelight Red, Solar Bronze, and Lunar Grey. Sizes run XS through XXL. RA Cycles offers bike fitting in Walnut Creek, California, and Brooklyn, New York, and it is the right first step with an integrated cockpit.

This is a bike for riders who want a pure aero race machine with a high-end Italian groupset, and who are comfortable committing to a fixed cockpit. It rewards riders who spend time on fast group rides and in races, where a tidy front end and a stiff, aerodynamic frame pay off.

The RA Perspective

The Filante SLR ID2 is a race bike first. It is fast, and the Campagnolo wireless groupset makes it feel finished in a way few bikes at this level do. The integrated cockpit keeps the front end uncluttered, and on a fast group ride or in a race you notice how settled the bike feels at speed.

Wilier says the ID2 saves about 14 watts at 40 km/h over the previous Filante. That is the manufacturer's own number, and we treat it as a reference, not a guarantee. What we can say is that the bike is built to hold a position and a pace for a long time.

The tradeoff is the cockpit. The F-Bar ID2 is a one-piece bar and stem, so you can't swap in a different stem length to change reach. Choose the size carefully, and talk to us about a fitting before you order. If you are between sizes, a fit session is worth it.

The 28 mm tires and the 700x34 maximum clearance mean it is a road bike that can handle rough pavement, but it is not a gravel or all-road machine. The 10-33 cassette with a 34-tooth small ring is generous for a race bike and handles long climbs well.

It is best for riders who already know they want an aero race bike and a Campagnolo groupset. When the plan is a fast group ride or a race on open roads, it is the bike we would reach for.
