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?

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 the 585-gram Aethos frame during a Tour stage.

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.

Key Features & Benefits

  • Aero in everything:Utilizing new UCI rules, the Tarmac SL8 has the narrowest, most aero seat post Specialized have ever made ensuring fast-moving, dirty air around the legs can flow back more cleanly.
  • Massive gains in stiffness-to-weight: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.
  • Shimano Dura-Ace Di2 groupset:Exceptional performance electronic shifting with a wide range cassette.

    View All FAQ's
    How does the DASH Store work?

    At DASH, we've created a Cycle to Work enabled storefront which allows you to browse and order a range of items, all whilst benefitting from savings of 28-47%. The cost of items you order is split into 12 months and deducted from your gross (or pre-tax) salary, allowing you to save on income tax and national insurance contributions, which is called salary sacrifice. After 12 months, you'll be able to continue using your items at no extra cost.

    What items are available on DASH Store?

    We have a range of items, from bikes and e-bikes, to accessories (such as helmets and locks), bike parts and tools, clothing (including jackets, shorts, shoes, and everything in between), even pre-owned bikes. We work with a range of brands so there's sure to be something you like in stock.

    Can I use other Cycle to Work scheme vouchers on DASH Store?

    Since we are a Cycle to Work scheme ourselves, we cannot accept vouchers from other scheme providers. If you would like to use DASH and already have a voucher, it might be worth speaking to your employer to see if they are able to refund it.
