Tarmac Compact

Whether it’s winning the Tour de France or a city-limit sprint, Tarmac is made for racing, with its powerful acceleration and razor-sharp handling. Shimano Tiagra components and our new DT-Axis 2.0 offer high performance and low cost.
  • FACT IS 8r carbon frame with tapered head tube and elliptical seatstays is race-ready stiff and fast without sacrificing compliance
  • The FACT carbon fork is light, stiff, and compliant with a tapered steerer
  • Significantly lighter than comparable-level wheelsets, these tough new DT-Axis 2.0 hoops roll smooth and fast
  • New Specialized Tarmac Comp alloy handlebar is stiff, tough, and light for serious performance
  • New 10-speed Shimano Tiagra STI shifters provide great value and high-performance
  • Specialized BG Romin Comp features a shaped profile for max power and hollow Cr-Mo rails for durability

Tech Features

WHAT High modulus carbon frame made from our most advanced carbon construction method.
WHY Gives our Tarmac the highest stiffness-to-weight ratio ever—19% greater than last year’s S-Works—which makes for an insanely light and fast bike.
HOW Divides frame 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.
WHAT Strategically designed head tube on SL4 frames tapers from 1-1/8” at the top to 1-3/8” at the crown and facilitates massive top and down tube junctions.
WHY Increases strength and stiffness for greater steering precision and responsiveness during out-of-the-saddle efforts.
HOW The wider base creates a stiffer, stronger junction, and the gradual transition of carbon fiber from top to bottom eliminates the potential for weak spots due to sharp angles—carbon is at its best when it keeps a smooth line. Uber-oversized top and down tubes “wrap” around the front of the head tube, creating the ultra-stiff and tapered “bulges” at the junctions. The design requires a smaller lower bearing (compared to last year's 1-1/2") which saves weight.
WHAT FACT IS construction with bottom bracket and chainstays constructed as one piece on on SL3 and SL4 frame levels.
WHY Optimizes weight and stiffness in one of the most critical and highest-stress areas of the frame for superior acceleration, efficiency, and handling.
HOW The BB and chainstays are molded together creating a single unit, rather than bonded together after molding, along with the carbon BB shell. This results in a super strong and stiff unit: seamless from the BB to the dropouts, eliminating potentially weak junctions. This design resists deflection under extreme pedal loads for improved power transfer.
WHAT Entire Tarmac family borrows technologies from the top-end, Pro Tour-winning S-Works models
WHY Increases performance and overall value in every Tarmac we make. Allows all riders to enjoy technology exclusively found on pro team-level bikes a year or two prior.
HOW Each year advancements from previous S-Works models trickle down to lower level bikes. For instance all frames use FACT IS construction—our most advanced carbon construction method—featuring triangulated seatstays, tapered head tube assemblies, and oversized tube sets for torsional stiffness and light weight.
