The Domane+ SLR 9 is a category-redefining carbon e-road bike built with intensely light 800 Series OCLV Carbon. It hides a compact, refined motor to elevate your ride with natural-feeling assist that quietly blends in with the elements, all but disappearing under you, so you stay more connected to the experience while enjoying extra power for crushing climbs and long, epic adventures.

The Domane+ SLR is our lightest e-bike ever, weighing only ~11.8 kg thanks to our best and lightest 800 Series OCLV Carbon and a smart frame designed to shave weight.

Designed to go the distance
An integrated 360Wh battery is hidden in the downtube and offers an impressive range of around 100 kilometers in Eco mode.

Optional Range Extender
Explore farther with an optional 160Wh Range Extender that gives you an extended total range of around 145 kilometers in Eco mode. Want even more miles? The Trek Connect App lets you customize your assist to extend your range even more.


The smooth advantage
Newly refined IsoSpeed soaks up fatiguing bumps and saves weight so you can ride stronger for longer.

Real road feel
A road-specific tune, narrow Q factor and intuitive mode change buttons on the hoods make the Domane+ SLR feel and handle like a traditional bike with the added benefits of electric.

All-road versatility
This Domane+ SLR comes with 32 mm smooth tyres that roll fast on tarmac roads, but has clearance for up to 40 mm tyres to enjoy every road, from smooth tarmac to gravel.


Shimano Dura-Ace Di2
The pinnacle of Shimano road technology and innovation, the new 12-speed Dura-Ace Di2 R9200 is Shimano’s fastest ever. Speed was the driving force behind this next-generation road group. That’s why every component was refined, designed and fine-tuned to make you faster – whether you’re sprinting to the finish on the Champs-Elysees or crushing your local climb.
