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.’

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.

As good as they said

I've owned S-Works Tarmacs in the SL4 and SL6 and loved both of them. I alternated between the two and could tell a lot of improvement in the SL6. The owner of my local bike store told me the SL8 was as great an improvement over the SL6 as the 6 was over the 4. I found it hard to believe there would be that much improvement because the SL6 was somewhat of a groundbreaking bike. This week I got the S-Works SL8 and I could tell as I was rolling down my block that the bike felt a lot different than my SL6. Within the first 5 miles I could tell that it was indeed as great an improvement over my SL6 as the SL6 was over the SL4. I love everything about it. The wheels are fantastic. The 12 speed Dura Ace shifts flawlessly. The bike cuts through the wind like a hot knife through butter and climbs easily. It's even more comfortable than my SL6. Don't think there's any room left for improvement. What on earth would they change when they come out with the SL9?

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!

Simply Awesome

What a great bicycle. Perfect in every aspect. Fast and comfortable and smooth shifting and braking. I think this bike has added 1 to 2 mph to my average speed. Goes over rough pavement very nicely. Specialized put a lot of thought and engineering into this bike and it show. Worth every penny.

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.
