2025 Trek Domane SL 6 Gen 4 – Endurance Road Bike with Electronic Precision
The Trek Domane SL 6 Gen 4 is engineered for endurance riders who crave speed, comfort, and versatility. Its lightweight carbon frame features rear IsoSpeed technology to smooth out rough roads, while a Shimano 105 Di2 electronic drivetrain delivers precise, effortless shifting. With 38mm tire clearance, tubeless-ready wheels, a fully integrated cockpit, and an internal storage compartment for essentials, this bike excels on everything from tarmac to cobbles, letting you ride longer and enjoy every mile.
KEY FEATURES |
The smooth advantage: Newly refined IsoSpeed soaks up fatiguing bumps and saves weight so you can ride stronger 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 tire clearance: Comes equipped with fast rolling 32mm tires, but offers clearance for up to 38mm tires so you can confidently ride everything from smooth pavement 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. |
