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.
Don’t forget your pedals
This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style. We recommend flats for versatility or clipless pedals for control and efficiency.
Connect, customize, calculate
The Trek Central app seamlessly connects to your Domane+ for real-time range calculations, activity tracking, and custom motor tuning. Plus, navigation and mapping features help you stay on course wherever you ride.
