{"product_id":"wilier-filante-slr-frameset","title":"Wilier Filante SLR Frameset","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eWilier Filante SLR Frameset\u003c\/strong\u003e is the starting point for the fastest road bike in Wilier's lineup — the same carbon chassis raced by the Groupama-FDJ WorldTour team when the race comes down to speed. Buying the frameset means building exactly the machine you want around a frame that has no peer in Wilier's catalog: a 870-gram monocoque carbon structure reinforced with a Crystal Liquid Polymer compound, engineered to push the absolute boundaries of stiffness-to-weight ratio in an aerodynamically optimized package. This is where the Filante SLR's reputation lives — the frame and fork you build around, not the components that come with it.\u003c\/p\u003e\n\u003cp\u003eWilier's aerodynamic development on the Filante SLR is thorough in a way that shows its professional racing origins. The tube profiles use NACA Airfoil and KAMM Tail geometries with deliberately rounded edges — a change from earlier sharp-edged designs that reduces turbulence and drag across a wider range of real-world angles. The fork interior has been widened by 7mm specifically to reduce the turbulent air column between the fork blades and the front wheel, a detail that only matters if you're serious about measured speed gains. The entire design was validated in a wind tunnel across -20 to +20 degree yaw angles, and then confirmed in real-world conditions — the kind of development program you get when the same frame is used by riders whose jobs depend on it being fast.\u003c\/p\u003e\n\u003cp\u003eAt 870 grams for a painted size M, the Filante SLR frame sits in rarefied company. The Crystal Liquid Polymer compound is what separates it from the Filante SL — a premium material that allows Wilier to simultaneously reduce weight and increase stiffness without the usual tradeoffs. The result is a frame that feels genuinely race-sharp under load: lateral stiffness when you're sprinting out of a corner, compliance where it matters for sustained riding, and a handling precision that comes from a chassis that doesn't flex where it shouldn't.\u003c\/p\u003e\n\u003cp\u003eThe fit system built into the Filante SLR frameset is unusually sophisticated for a race bike at this level. The Filante Integrated Carbon Bar\/Stem is available in five stem lengths and accommodates up to 35mm of spacers under the bar, creating 240 distinct accufit points across the six frame sizes. Add the two seatpost setback options and that number effectively doubles to 480 individual fit configurations. The geometry — identical to the Filante SL — is carried by the same steep seat tube angle and aggressive stack\/reach relationship, but the fit range means this frame works for a wider variety of rider proportions than the numbers alone suggest. Riders who prefer an alternative cockpit can fit a V-Bar or Z-Bar with Wilier carbon spacers.\u003c\/p\u003e\n\u003cp\u003eIntegration is complete. All cables route internally through the Filante Bar and into the frame via Wilier's proprietary superthin bearing at the headset — a component Wilier Triestina designs and manufactures independently, not sourced from the open market, and available for service only through authorized dealers. There is no external cable housing on a properly built Filante SLR. The Speed Release thru-axle system — 12x100mm front, 12x142mm rear, with Miche thru-axles included — makes wheel changes fast and secure. The frame is compatible with electronic groupsets only and disc brakes only; no provision exists for mechanical shifting or rim brakes. This is a dedicated racing instrument.\u003c\/p\u003e\n\u003cp\u003eTen colorways are available, ranging from understated options like Blue White Glossy, Grey Glossy, and Silver Blue Glossy to premium special editions: the Groupama-FDJ team replica, the Tricolore, Ramato, and White Gold. Pricing varies by colorway — $6,800 for standard colors, up to $8,000 for special editions. All are available in six sizes from XS to XXL.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e870g painted frame (size M)\u003c\/strong\u003e — Crystal Liquid Polymer compound delivers climbing-bike weight with aero-bike stiffness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNACA Airfoil and KAMM Tail profiles with rounded edges\u003c\/strong\u003e — reduces drag and turbulence across the full range of real-world riding angles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFork interior widened 7mm\u003c\/strong\u003e — purpose-built reduction in turbulence between fork blades and front wheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWind tunnel validated at -20° to +20° yaw\u003c\/strong\u003e — tested across the angles that matter in actual racing conditions, not just ideal lab setups\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e240–480 accufit positions\u003c\/strong\u003e — five stem lengths, 35mm spacer range, and two seatpost setbacks accommodate an exceptionally wide fit range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProprietary superthin headset bearing\u003c\/strong\u003e — full internal cable routing with zero external housing; Wilier-owned design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorldTour proven\u003c\/strong\u003e — the active race frame of the Groupama-FDJ team, available in team replica colorway\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eFinal Take\u003c\/h3\u003e\n\u003cp\u003eThe Wilier Filante SLR Frameset is for the rider who wants to build their fastest road bike from the ground up on a proven WorldTour chassis. The 870g frame, Crystal Liquid Polymer carbon, thorough aero development, and near-unlimited fit range make it one of the most technically accomplished framesets available at this price. Build it with the groupset you want, the wheels you've been waiting to run, and the saddle that actually fits — and you'll have a race bike that's faster and more dialed than almost anything you could buy off the shelf.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Wilier","offers":[{"title":"Blue White Glossy \/ XS","offer_id":44141729579052,"sku":"E303
