Trek Domane SL 5 Gen 4 Carbon Road Bike 2026

The Domane SL 5 is an endurance road bike ready to comfortably take on rough roads and long miles in comfort. It's crafted with a lightweight 500 Series OCLV Carbon frame speced with a reliable Shimano 105 drivetrain, and aluminium wheels and aluminium handlebars to balance performance and price.

The smooth advantage

Newly refined IsoSpeed soaks up fatiguing bumps and saves weight so you can ride stronger for longer.

Podium-topping speed

Raced to victory on the infamous cobblestones of Paris-Roubaix, the new carbon Domane is faster than ever thanks to new aerodynamic improvements and an ultra-light design.

Lighter than ever

Light and strong 500 Series OCLV Carbon and a new gram-saving design make this the lightest Domane SL disc ever.

Versatile tyre clearance

Comes equipped with fast-rolling 32 mm tyres, but offers clearance for up to 38 mm tyres so you can confidently ride everything from smooth tarmac to light gravel.

Internal storage

Internal downtube storage and top tube bag mounts make it easy to carry everything you need for all-day rides.

Refined integration

Domane is more integrated than ever, with hidden cables and a hidden seatpost clamp.

Shimano 105

With shift technology inherited from mechanical Ultegra and Dura-Ace, Shimano 105 gives you top-shelf shifting at a budget-friendly price. Whether you’re commuting year-round or training for the big race, Shimano 105 is a workhorse drivetrain that won’t hold you back as you grow in the sport.

Don’t forget your pedals

This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style. We recommend clipless road pedals for control and efficiency.
