Magnificent, isn't it?

The design team and engineers at Trek wanted to keep the best elements of the previous Domane SL 5, but improve the 2020 bike's overall performance in a wider range of conditions. From terrible pavement to relentless hills to gusty crosswinds, the 2020 Domane is better everywhere. The frame and fork were given an aero treatment, allowing it to slice through the wind with less effort by the rider. Cable routing tucks in behind the stem, making the bike even sleeker. A Kammtail shape was used at the back of the frame's down tube and seat tube, reducing overall drag in headwinds. Aerodynamics weren't the only thing considered for the updated Domane SL 5. Clearance for 38mm tires has been added, allowing for wider, more adventurous rubber. A storage compartment in the down tube practically eliminates the need for a tool kit bag under the saddle. A single lever opens it, and a port for a multi-tool (sold separately, along with the rest of the flat repair kit) sits just inside. This feature lowers the bike's center of gravity, improving handling on poor pavement and high-speed turns (or both). 

The Domane hasn't forgotten its roots, though. Built with Trek's proprietary 500 Series OCLV carbon fiber, the Domane SL's frame exhibits incredible strength as well as light weight, just like the best-selling previous generation. The front and rear IsoSpeed decouplers are still there, making short work of harsh tarmac and potholes. Even the Endurance fit and geometry that allows a wider range of riders -and rider flexibilities- to get comfortable remains in all sizes. An aperture in the left chainstay for a DuoTrap S speed/cadence sensor (sold separately) makes for a clean installation, while a 3S chain keeper prevents dropped chains and roadside stops (and greasy fingers). 12mm thru-axles not only make hub installation a snap, but improve the frameset's torsional strength for better power transfer and high-speed handling. The Domane's new T47 bottom bracket is far less likely to creak after prolonged miles. No, they didn't rest on their laurels when they revisited the Domane SL 5.

In the drivetrain department, Trek chose Shimano's recently revised 11-speed 105 components for the Domane SL 5. Changes and improvements to the venerable component group include:


  • A Shadow-style rear derailleur with a wider gearing capacity (up to 34T!), improved aero profile, and a lighter touch at the shifter under pedaling loads
  • A toggle-pivot front derailleur requiring less effort to operate at the shift lever
  • A stiffer 50/34T compact crankset with a more aero profile
  • Reshaped levers with an improved hood texture and adjustable lever reach for smaller hands
  • Flat-mount hydraulic brake calipers boast lighter weight and improved torsional stength compared to post-mount units
  • An 11-34T cassette that allows a 1-to-1 gear ratio for tackling exceptionally steep grades


 Rolling stock consists of Bontrager's tubeless-ready alloy Affinity Disc wheels, featuring a 21mm width for wide, road-holding rubber. 700x32c Bontrager R1 Hard-Case Lite tires bring an extra layer of smoothness to every mile. A Bontrager Arvada Comp saddle sits atop a carbon fiber micro-adjust seatmast cap that boasts a mount for a tail light. An accessory-ready alloy Bontrager Elite Blendr stem and alloy Bontrager Comp VR road handlebar complete this well-engineered masterpiece.
