After eight generations and over two decades of development, it’s more than the fastest Tarmac ever - it’s the world’s fastest race bike. Your legs up for it? Aerodynamics or lightweight alone don’t win races - speed is what matters. Delivering that speed requires creating an uncompromising combination of aerodynamics, lightweight, stiffness, and compliance. Through race simulations using real world data our Ride Science team knows the Tarmac SL8 is the fastest race bike ever made on the routes that matter - 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo, 20 seconds faster over the legendary Tourmalet climb.\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAERO IN EVERYTHING: We’re putting aero where it matters - the leading edge - not just where it looks good. In the process we’ve created our most aerodynamic road bike ever. Yes, it’s more aero than the Venge. Clean air is optimized for maximum advantage with the Tarmac’s new nose cone - the Speed Sniffer. By moving the steer tube back - the tube that determines head tube width - the leading edge of the head tube can be much sharper, delivering a much lower drag shape. Utilizing new UCI rules, the Tarmac SL8 has the narrowest, most aero seat post we’ve ever made ensuring fast moving, dirty air around the legs can flow back more cleanly. Doesn’t victory smell sweet?\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 class=\"accordion__title inline-richtext h4\"\u003eSPECIFICATION\u003c\/h4\u003e\n\u003ctable cellspacing=\"0\" cellpadding=\"6\" border=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFrame\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTarmac SL8 FACT 10r Carbon, Rider First Engineered™, Win Tunnel Engineered, Clean Routing, Threaded BB, 12x142mm thru-axle, flat-mount disc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFork\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFACT 10r Carbon, 12x100mm thru-axle, flat-mount disc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCrankset\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eShimano 105 R7100, 52\/36t\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eChain\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eShimano SLX CN-M7100, 12-speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCassette\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eShimano 105 CS-R7100, 12-speed, 11-34t\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eShift Levers\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eShimano 105 Di2 R7170, 12-speed hydraulic disc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFront Derailleur\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eShimano 105 R7170, braze-on\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRear Derailleur\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eShimano 105 Di2 R7150. 12-speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFront Brake\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eShimano 105 Hydraulic Brake\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRear Brake\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eShimano 105 Hydraulic Brake\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFront Wheel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDT Swiss R470 rim, 20mm internal width, tubeless ready, 24h, Specialized full sealed bearing thru axle hub, centerlock disc, DT Swiss Champion 14G stainless steel spokes, DT Swiss brass nipples.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRear Wheel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDT Swiss R470 rim, 20mm internal width, tubeless ready, 24h, Specialized full sealed bearing thru axle hub, centerlock disc, DT Swiss Champion 14G stainless steel spokes, DT Swiss brass nipples.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFront Tyre\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eS-Works Turbo, 120 TPI, folding bead, BlackBelt protection, 700x26mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRear Tyre\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eS-Works Turbo, 120 TPI, folding bead, BlackBelt protection, 700x26mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHandlebars\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSpecialized Shallow Drop, 6061, 70x125mm, 31.8mm clamp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSaddle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBody Geometry Power Sport, steel rails\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeat Post\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eS-Works Tarmac SL8 Carbon seat post, FACT Carbon, 15mm offset\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeat Binder\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTarmac integrated wedge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInner Tubes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTurbo Ultralight, 48mm Presta valve\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBottom Bracket\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eShimano Threaded BSA BB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHeadset\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStem headset spacers kit for SL7 stem \u0026amp;
