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.

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

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 tyre clearance, it adds up to an unprecedented ride quality.

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-rounders 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.

  • The Tarmac SL8 Expert delivers exceptional performance with a full SRAM Rival eTap AXS groupset with power meter, C38 carbon tubeless ready wheelset, and an SL7 stem with Specialized Expert Shallow Drop alloy handlebars makes for an accessible performance-packed bike.

Great bike but…

More like 4.5 stars, but I’ll round it up. Have satin powder indigo. Great color and finish! Overall, the frame is fast and ride smooth. Handles great. Bike has aluminum drop bars. Very disappointing at this price point. It has to be carbon and aero. Also, I had to upgraded the DT Swiss hub from 18t to 36t star ratchet. Easy install but should have been stock with the Roval wheels.

SL8 Expert Headset Clearance

Hello, the bike is sweet and has been so much fun to ride (hence the 4 stars). That being said I think I may have gotten a lemon or the Specialized shop that put it together didn’t install the headset correctly. For some reason, the dust cap has rubbed against the frame and it wore down the paint/frame right around the headset area. I just noticed this after cleaning the bike this past weekend. I took it to an Incycle shop near me and they advised that the clearance between the headset and frame is not ideal on my bike. I am pretty bummed to have this happened to my bike, it was very expensive and I’ve taken extremely good care of it. The shop emailed the warranty department to see what they thought of it so hoping they can replace the frame and install a new headset with the right amount of clearance in this particular area. Fingers crossed!

Great expert level bike

Geometry is both comfortable and aero position, this's almost impossible to find in other bikes, the frame is stiff and feels as smooth as butter, the Roval carbon wheel-set is light and stiff making the ride fast, the grip of the S-Work tyres is high on tarmac yet has minimum surface contact. With this bike, I was performing as good as Pro bikes with DuraAce group-set, the frame is definitely a the secret sauce here.

50살에 딱 맞는 자전거.

자전거 출퇴근을 위해 샀다. 평생 운동 한번 안해본 몸으로 주행 20Km 완주 평속 15Km. 최고 속도 20Km. 페달링을(왼쪽으로 진행) 뒤꿈치로 11시 방향에서 7시방향 일때만 지렛대 원리를 이용 발목을 꺽어 힘주었다. 평속 25Km. 최고속도 38Km로 변했다. 70Km 완주. 달리는 쾌감을 알려준 자전거.
