THE TARMAC SL4 MCLAREN IS SO LIGHT, STIFF AND SO EXPENSIVE WE ARE ONLY MAKING FIVE HUNDRED
YOU WON’T BELIEVE IT With a highly successful spring season behind us, we proudly add numerous victories to our list of incredible accomplishments in the pro peloton. But it’s easy to forget that when we first jumped into the professional road game, over 10 years ago, we were seen as an American mountain bike brand which had no place trying to shake things up. Soon after Specialized started racing in Europe, I was out on one of my long “thinking rides.” It was this ride where I first came up with the Tarmac name and concept. We built several prototypes, which culminated in Italian racing legend Mario Cipollini racing the original S-Works Tarmac E5 in the 2003 Giro d’Italia, Tour of Georgia, and Vuelta a España. In 2005 the first full-carbon Tarmac was born and raced by Team Gerolsteiner to victory in Stage 14 of the Tour de France and the San Francisco Grand Prix. I worked on that bike, and I’ve worked on every Tarmac since: the Tarmac SL, SL2, SL3, and now the all-new Tarmac SL4–our lightest and stiffest Tarmac ever. During these years, I’ve watched, sometimes from the team car, as the Tarmac has collected an astonishing number of wins, including the Tour of Flanders four straight times, a World Championship, a dominant 1-2 finish at last year’s Tour de France… and now the Giro d’Italia. I’ve personally worked with riders, ridden with them, and incorporated their feedback into each new iteration of the Tarmac. Our new Tarmac SL4 is truly remarkable in its stiffness-to-weight ratio—a critical factor in racing performance—with a 19% improvement over last year’s industry-leading frame. With features like the King Cobra tapered head tube, one-piece BB/chainstay, and internal cable routing, we’ve distilled this machine down to the purest expression of racing performance. The SL4 is the flagship of our road racing program. Alongside the Tarmac SL3, Roubaix, Shiv, and Venge, we offer the most dominant and complete race collection in the industry. While we know we’re still not always welcomed by traditionalists, we stopped listening to them a long time ago. Over 10 years ago, to be exact. We’re only interested in listening to the riders, so we can keep making the best and fastest bikes.

TECHNOLOGY
STIFFNESS The overall torsional stiffness of a bike is the single best determinant of its acceleration and handling. So nothing was spared in making the SL4 the stiffest frameset and complete module possible, without sacrificing ride quality. The high-modulus carbon frame, with massive top and down tubes, is constructed in our most advanced FACT IS method: The frame is divided into four monocoque sections (plus dropouts)—with carbon fibers running continuously from tube to tube within each section—for more precise optimization of tubes shapes, sizes, and joints. With advancements like our King Cobra head tube, strategically placed ultra-stiff pitch fiber, internal ribbing, and tweaks to seatstays and fork, we were able to create the stiffest race bike on the market, and realize an amazing 19% increase in stiffness-to-weight ratio over last year’s industry-leading SL3.
TORSIONAL STIFFNESS (N*m/deg)
WEIGHT We could have made the SL4 lighter, but we refused to compromise the explosive acceleration or sharp handling Tarmac riders demand. So we shaved every gram possible—it remains one of the lightest framesets in the industry—while maintaining these essential ride characteristics. The new head tube design means less material and a smaller, lighter lower bearing. We also save material through our proprietary internal ribbing in the head tube and BB, while the new hollow carbon front and rear dropouts are feather light but remain stiff and durable. Throw in an impressive 10% weight reduction in the fork plus our uber-light S-Works crankset and the complete module weighs in at a scant 1995 grams.
FRAME MODULE SYSTEM WEIGHT (g)
KING COBRA HEAD TUBE Our proprietary King Cobra tapered head tube has allowed us to achieve the best of all worlds: save weight, increase torsional stiffness, and improve vertical compliance. Through “wrapping” super oversized down and top tubes partially around the tapered head tube, thereby eliminating flat surfaces and smoothing transitions, we’ve stiffened and strengthened these critical junctions so much that we are now able to use a narrower head tube (only 1-3/8” at the crown, down from 1-1/2”). This of course also means less material in the head tube and a smaller bearing, resulting in considerable weight savings. Finally, the narrower, 1-3/8” head tube/crown interface means no sacrifice in ride quality.
ONE PIECE BB/CHAINSTAY With FACT IS construction on the SL4 frames, the bottom bracket and chainstays are constructed as one piece, optimizing weight and stiffness in this critical and highstress area, improving acceleration, efficiency, and handling. The oversized BB and chainstays are molded together creating a single unit, rather than bonded together after molding, along with the carbon BB shell. This super strong and stiff unit is seamless from the BB to the dropouts, eliminating potentially weak junctions. This design resists deflection under extreme pedal loads for improved power transfer.

SEATSTAYS The new seatstay design features a significantly wider stance which improves lateral stiffness. Plus specifically-engineered, dual-taper shaping near the bridge optimizes overall brake performance.
CARBON DROPOUTS Front and rear hollow carbon dropouts provide a stiffer interface with the wheels for improved handling and efficiency. The front and rear dropouts also feature co-molded steel inserts for added durability when taking wheels on or off. Rear dropouts are also designed to allow for cable routing through the seatstays.
INTERNAL CABLE ROUTING Rear brake cable is routed through the top tube and both derailleur cables run through the down tube, with the rear cable continuing through the chainstay. This protects the cables from the elements and road grime, assuring optimal shifting and braking performance with lower maintenance. It also keeps this frame looking as sleek and sexy as possible!
