A Partnership Created at the Top

For years, the Specialized Tarmac has been a reference point for pinnacle road bike performance. As such, we’re thrilled that the iconic Californian brand has chosen to spec our SLT Headset Bearings as standard on their top-tier S-Works SL8 models for ultimate reliability.

Now in its eighth generation, the Specialized Tarmac combines aerodynamics, lightweight, and ride quality to create the fastest bike for the world's biggest races.

In true Specialized fashion, it’s a bike where no engineering or design choices are left up to chance. Everything has been meticulously developed to create their version of the ultimate road racing bike.  


We chose to spec SLT headset bearings on the Tarmac because they deliver exceptional performance for our riders. Long-term durability and low maintenance are key — and the lifetime warranty is a bonus. These CeramicSpeed bearings are a perfect match for the Tarmac, where every detail matters

Specialized’s choice of speccing our SLT Headset Bearings on the S-Works Tarmac SL8 was informed and influenced by our mutual partners from Soudal Quick-Step.

Our partnership with the storied Belgian team spans over a decade, and like Specialized, we rely on their expertise and feedback when developing products.

The Wolfpack has put our SLT Headset Bearings through their paces in the world’s biggest races and has validated their performance at the WorldTour level.

"For our mechanics, I would call the SLT Bearings a game-changer as they save them hours of work. We’ve spent countless hours testing them at races and in training, continually fine-tuning them until we’ve reached the perfect result.

The connection and way of working with Ceramicspeed is a mentality that I love! We’re working closely together, catching up every month, and adjusting product details, if needed. It’s the perfect example of a technical partnership!"

Nicolas Coosemans, Technical & Development Manager at Soudal Quick-Step

Our SLT (Solid Lubrication Technology) Headset Bearings feature an oil-encapsulated solid plastic polymer and stainless-steel materials, making them self-lubricating, corrosion-resistant, and maintenance-free.
