Trek Domane SL 6 Gen 4

The latest generation of Trek's ground-breaking Domane is here! The accommodating fit and brilliant road manners are unchanged, but the Domane SL frameset has undergone some serious refinements.

The Domane SL 6 is built around a lightweight 500-series OCLV Carbon frame. Not too different than last year's, right? That 500-series carbon fiber "recipe" and frame shaping has been refined for lighter weight and better aerodynamics. Trek also simplified the Domane SL frame with a lighter version of their award-winning rear IsoSpeed unit found at the seat tube/top tube junction. By using a more classic seatpost and internal collar, Trek kept the weight low while retaining all the ride-smoothing characteristics that made the Domane SL such a hit. The front IsoSpeed unit found in the previous version was removed for further weight savings. 32c tubeless tires were doing a better job of keeping the rider more comfortable. Tires up to 38mm wide can be added for for more adventurous riding! Kammtail Virtual Foil (or KVF) frame shaping has been rethought, allowing the Domane SL 6 to slice through the air even better than the previous model. Even if you don't race, the Domane SL 6 will help battle frustrating headwinds. The storage compartment in the down tube was kept, keeping the bike looking clean and sleek. Organizing your tool kit is easy, thanks to the included Bontrager BITS Internal Frame Storage Bag. Internal cable routing has also been refined with a new stem and brake hose aperture in the head tube. The top tube boasts a mount for a "tank bag" (sold separately) to be mounted just behind the stem.

Shimano has made electronic shifting more affordable with their introduction of their latest 12-speed Di2 105 component group. It shares many of the same features that make electronic shifting so useful for so many:

• Lightning-quick shifts with the latest generation Di2 derailleurs and wireless Di2 dual-control levers


• Programmable shifting for righties and lefties with Shimano's E-Tube Project smartphone app


• Wireless shift signal can be received by most 3rd party handlebar computers from Garmin and Wahoo


• Larger 36T rear cassette cog capacity on the 105 Di2 derailleur


• The internal battery is wired to both derailleurs and is charged by a new aperture at the rear derailleur

The Domane SL 6's Shimano 12-speed 105 drivetrain can help make short work of challenging terrain, thanks to a 50/34T alloy compact crankset and 11-34T Shimano 105 cassette. Yes, that's a 1-to-1 ratio for tackling fearsome inclines! Bontrager's alloy Paradigm Comp 25 tubeless alloy wheelset is shod with tubeless Bontrager R3 hard-Case Lite 700x32c tires, delivering easy acceleration and confident grip on rough and choppy pavement. The Domane SL 6's hydraulic disc brakes are also Shimano 105 units, bringing effective stopping power in all conditions, rain or shine. Bontrager also supplies the Verse Short Comp saddle, Domane carbon fiber seatpost, alloy RCS Pro stem and alloy Elite IsoZone VR-SF road handlebar.
