Tarmac SL8 Expert

Delivery Icon

We deliver! Just say when and how.

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.

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.
