Specialized Tarmac SL8 Pro Ultegra Di2 Carbon Road Bike 2025 in Gloss Liquid Silver/Blue Pearl Over Black
£8,250.00
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.
The Tarmac SL8 Pro delivers exceptional performance with a full Shimano Ultegra 8100 series Di2 groupset with power meter, Roval Rapide CL II tubeless-ready wheelset, and a Roval Rapide Cockpit, Integrated Bar/Stem. You’re ready to race out of the box.
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 Ultegra Di2 groupset:Exceptional performance electronic shifting with a wide range cassette.
