The Domane has become a crowd favorite here at Machinery Row, but the price of the SL models were a bit daunting for some. The Domane SL 4 lowers the barrier to Trek's outstanding road masterpiece!


Starting with Trek's exclusive 500 Series OCLV carbon fiber, the Domane SL 4's frame boasts light weight and impressive torsional strength. Stable handling, instant pedaling response and feather-lightness are all part of the Domane SL 4's bragging rights. The Domane SL models for 2020 feature a more aerodynamic frame and fork treatment, helping to cheat the wind. Even the brake and shifter lines get tucked away behind the stem. The Endurance geometry of the Domane SL 4 is more upright and stable, allowing a wider range of riders -and rider flexibilties- to get comfortable. The open secret to the Domane's ultra-smooth ride quality is IsoSpeed technology. Front and rear decouplers at the frame's seat tube/top tube juncture and top of the head tube allow the bike to soak up impacts and road chatter, keeping the rider fresher for longer. The frame details are useful as well, including 12mm thru-axles front and rear, vanishing fender mounts and even an aperture on the left chainstay for a DuoTrap S speed/cadence sensor (sold separately). Trek even added a downtube storage compartment to all the Domane SL models, eliminating the need for a seat bag to store tools and an inner tube. Cool, huh? There's room for tires up to 38c, allowing excursions down unpaved roads and trails!


The drivetrain that Trek added to the Domane SL 4 won't hold you back, featuring 10-speed Shimano Tiagra dual-control levers, Tiagra derailleurs, Tiagra and a 12-28T Tiagra cassette. An alloy Praxis Alba crankset with a 50/34T compact chainring combination adds a wide gearing range for tackling challenging inclines. Bontrager supplies the tubeless-ready alloy Affinity Disc wheelset and 700x32c R1 road tires, bringing effortless speed and a smooth feel. Shimano Tiagra hydraulic disc brakes help reign in speed in all conditions, rain or shine. A Bontrager Arvada Comp saddle, alloy Bontrager Comp VR series road handlebar and accessory-ready alloy Elite Blendr stem completes this value-packed performance machine.
