Trek Domane SL 6 (Gen 4) Performance Road Bike 2025
Domane SL 6 is an endurance road bike that's light, aerodynamic, and built to take on long, rough miles in the saddle. With the huge advantage of an electronic Shimano 105 Di2 drivetrain and clearance for 38mm tires, Domane SL 6 is ready to soar over cobbles and tarmac alike. A fully integrated cockpit keeps your setup looking as sleek as it feels and an easy-access storage compartment stows ride essentials. Pair that with road-smoothing rear IsoSpeed, easy-access internal storage, tubeless-ready wheels and you'll be riding longer—and having more fun—than you ever thought possible.
It's right for you if...
Every ride might start on the pavement, but that doesn't mean it'll end there. You want a ride that balances versatility, comfort, and speed. Looks are important, but so is reliability, and you love the high-tech electronic setup of the Shimano 105 Di2 drivetrain and stopping power of hydraulic disc brakes. Finished off with a carbon frame and rear IsoSpeed, you know every ride is going to be a dream.
The tech you get
A light and refined 500 Series OCLV Carbon frame with road-smoothing rear IsoSpeed. A Shimano 105 Di2 2x12-speed electronic drivetrain, and powerful flat-mount disc brakes. Plus, wide Bontrager Paradigm Comp 25 tubeless ready wheels, internal storage, and cable routing that add to the bike's capability and sleek look. Added top tube mounts let you secure bags for longer rides without bulky straps and bungees.
The final word
All the road-smoothing benefits of a carbon Domane, with fully wireless Shimano 105 Di2 shifting. This bike is comfortable, fast, light and ready for adventure — with lofty 38mm tire clearance that keeps you floating on paved roads and light gravel alike.
Why you'll love it
- Domane SL Gen 4's rear IsoSpeed, integrated cables, and aero Kammtail tube shapes come together for a fast, lightweight, and road-smoothing ride
- This bike is super versatile and equally suited to all-day adventures on the open road, club rides, and racing
- Shimano's 105 Di2 wireless electronic drivetrain delivers precision shifts that won't leave a hole in your wallet
- Road-smoothing IsoSpeed and clearance for up to 38mm tires absorbs fatiguing bumps in the road for a smoother, more comfortable ride
- A convenient internal storage compartment gives you a versatile spot to stow tools and gear, while top tube mounts let you cleanly bolt on a bag for all day adventures
