1974 to 2024: A 50-Year Tradition of Innovation

As Specialized celebrates its 50th Anniversary of innovating to improve riders’ lives, we have our sites set on the next half century and creating the future of cycling. Join us as we look back at five decades of innovation so we can continue to Pedal the Planet Forward together.

One Bike to Rule Them All
Tarmac SL8

One Bike to Rule Them All

The engineering obsessed Germans at Tour Magazine declared the Tarmac SL8, ‘the best road bike in the world’. Reaching the previously unimaginable rating of ’1.3’ *- the highest Tour score ever - Tarmac SL8 beats every competitor. Or, as these serious, data driven journalists put it, ‘No other racing bike functions better as a complete package.’

Aero In Everything
Our Most Aero Race Bike Ever

Aero In Everything

After a decade of working in the Win Tunnel, our engineers put aero where it matters, not just where it looks good. The result? A new Nose Cone called the ‘Speed Sniffer’ helps the new Tarmac SL8 be 16.6 seconds faster over 40km than the Tarmac SL7. And yes, more aero than the Venge.

Minimum Weight, Maximum Aero
685 Gram Frameset

Minimum Weight, Maximum Aero

We saw how the lightest production road bike in the world - the Aethos - could marry blistering response in the mountains with a supple, all-day ride. The Tarmac SL8 took those learnings from Aethos to be easily built at the UCI minimum with a full aero set up.

Goes Like Hell, Rides Like Heaven

Goes Like Hell, Rides Like Heaven

The Tarmac SL8 delivers a massive 33% improvement in stiffness to weight vs the SL7, all while being 6% smoother in the saddle. With World Championship proven geometry and 32mm tire clearance, it adds up to an unprecedented ride quality.

The Tarmac SL 8 White Paper

Our Ride Science team tests our solutions versus the competition before a pedal is even turned. Through complex simulations of real world race routes with identical real world data, our Ride Science team knows the Tarmac SL8 is the fastest race bike ever made.

Aren’t You Glad Some Kids Stayed in Science Club?

Creating a bike more aerodynamic, 15% lighter, with a 33% improvement in stiffness-to-weight than the 4X World Championship winning Tarmac SL7 took more than an obsessive commitment to Innovate or Die. Our engineering team created an entirely new process.

Made in Racing

Since day one at Specialized, the rider has been the boss, so the best all arounders in the world - Remco Evenepoel, Demi Vollering - had a hand in developing and refining the Tarmac SL8. Ultimately, we co-created the fastest race bike in the world.

Nothing is faster than the Tarmac SL8 thanks to a combination of aerodynamics, lightweight, and ride quality previously thought impossible. 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.

  • AERO 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?

  • MINIMUM WEIGHT, MAXIMUM AERO: Tarmac SL8 took learnings from Aethos to be easily built at the UCI minimum with a full aero set up. The team delivered a mind bending, scale tickling 685 gram frame - 15% lighter than the Tarmac SL7 and lighter than anything on else on the World Tour*. With the ability to make lightweight a top priority in the down tube, seat tube, and rear of the bike lessons from Aethos were applied. The frame’s shape carries load so efficiently that extra carbon stiffness layers become redundant. *Unless of course you count the time Kasper Asgreen raced our 585 gram Aethos frame during a Tour stage.

  • GOES LIKE HELL, RIDES LIKE HEAVEN: With massive gains in stiffness-to-weight - an improvement of 33% over the SL7 - the Tarmac SL8 takes legendary handling, aggressive responsiveness and World Championship proven geometry to the next level. The bike is stiffer at the pedals, more precise at the bars, and combines it with a compliant ride in the saddle that sets a new benchmark for race bike comfort. Thanks to our Rider-First Engineering, every rider, regardless of size, gets the same unprecedented ride quality and handling. In the saddle the Tarmac SL8 delivers 6% more compliance, floating over rough road with a supple feel unique in the high strung world of race bikes. Tarmac’s proven geometry and 32mm tire clearance are identical to the SL7, ensuring easy adaptation and the versatility to run higher volume tires when needed.

  • BEYOND GENDER: There can be more difference between two male cyclists than between a male and female. Gender alone doesn’t provide nearly enough data to specialize and that means creating male or female bikes is arbitrary and outdated. Every rider can get the next level advantage of Tarmac SL8. It’s time to go Beyond Gender.

  • S-Works Tarmac SL8 is spec’d with only the best components. A full Shimano Dura-Ace 9200 series Di2 groupset with dual-sided power meter, and a Roval Rapide CLX II tubeless-ready wheelset is the perfect complement to the world’s fastest frame. All S-Works Tarmac SL8 models ship with a Roval Rapide cockpit to save weight and for the fastest possible leading edge.

Incredible Bike

I was blown away by the difference in the SL8 from my previous road bike. The bike just wants to go fast and is coupled with incredible handling and is unbelievably light weight. Every detail has been considered in the design. I was a skeptic of the hype before purchasing it, but am a believer now.

9 Months in...

After 9 months, and almost 3,500 miles, I love this bike just as much as the day I picked it up! It's fast, comfortable, light weight and looks the business in Viavi Cyan Blue colorway. My only two wishes: 1. A lighter stock wheelset - 1520g is average, but they should really be 1350g (but please DON'T go hookless). 2. The 4iii power meter - goes through a set of batteries every other month. Specs say 100 hours of run time, but I'm not sure I'm even getting that. Aside from those two, the bike is PERFECT! If you're on the fence, make the jump!

Traumrad

Ich bin Sphären vom Dasein eines Radprofis entfernt. Nichts desto trotz habe ich mir jetzt den lange gehegten Wunsch eines Profirennrades erfüllt und habe dieses traumhafte Rennrad in Vollendung des Tarmac SL8 als S-Works-Ausführung gefunden. Die Ausstattung lässt keine Wünsche offen. Man fühlt sich im Sattel sofort wohl. Trotz des sportlichen Anspruchs fährt sich das Rad relativ komfortabel. Über die intuitive Bedienung, die Leichtigkeit, die Aerodynamik, die Beschleunigung und das Handling wurde schon ausführlich berichtet. Dass man auf dem Rad aber relativ bequem sitzt, ist für einen Nichtprofi unbedingt kaufüberzeugend da ansonsten womöglich schnell die Freude an den anderen Vorteilen schwinden würde. Ein tolles Rad! Die tolle Farbe kommt im übrigen nur bei Sonnenlicht zur Geltung - schaut euch das mal an! Das Rad ist nämlich in Realität nicht langweilig weiß!

Una obra de arte

Mejora en su eficiencia de pedalada y con el adn de las predecesoras, es más confortable y ágil en las bajadas. Si te preguntas si vale la pena, te aseguro que si.

Perfect.

After having a Venge, then SL6, then Aethos; the Tarmac SL8 is exactly what I wanted. Venge speed with Aethos weight and comfort. Absolutely love it. Boris at Sheepshead Bay is just the best when it comes to getting top-end gear and taking care of all the little details.
