Everything you love about road riding, nothing you don’t
The all-new Domane+ SLR electric road bike
An e-road bike unlike ever before
Take the tailwind with you and leave your limits behind on the all-new Domane+ SLR.With a groundbreaking ratio of lightweight design and high-speed assist, Domane+ SLR offers pro peloton power and real road feel in a shockingly sleek and speedy package. This performance e-road bike looks, sounds, fits, and feels like a traditional road bike, with a discreet, natural-feeling assist that helps you fly up climbs, hang with the fast group, and venture to places far, far away.
So, go ahead – take the long way home. With Domane+ SLR, there’s always room for more miles, more speed, and more fun.
All speed. No limits.
More than meets the eye
True power lies within. Hidden behind the front chainring, Domane+ SLR’s harmonic pin ring transmission blends seamlessly into the frame, and its compact design offers a Q factor similar to a traditional road bike for a more comfortable ride. Plus, a compact but powerful 360Wh battery allows for a smaller downtube than most e-road bikes, resulting in a sleek and subtle ride your friends won’t believe is electric.
Shockingly light, thrillingly fast
Most e-road bikes make you choose between light weight and high speed. Domane+ SLR offers
the best of both worlds, weighing in at just ~26 pounds with a fast max assist of 28mph.
Our best and lightest carbon
Premium 800 Series OCLV Carbon helps make Domane+ SLR our lightest e-road bike ever.
A compact harmonic pin ring motor saves weight while providing a natural feeling assist.
One of the best parts about road riding is the moment when the rest of the world fades away. When all that’s left is the open road, the hum of rubber on pavement, and the rhythm of your deepening breath. Domane+ SLR’s remarkably quiet and discreet e-system limits distracting noises so you can focus on the people and places that surround you.
Data recorded in an anechoic chamber using a TQ system and calibrated B&K 4966-h-041 microphone and Siemens SCADAS data acquisition unit with an acoustically isolated Wahoo Kickr trainer set to 300W total resistance and bikes in maximum assist mode. Microphone was located 1 m laterally from the bottom bracket and 1.7 m off the floor (head height) and sampled at 51,200 Hz. Tonality calculated in Siemens Testlab Neo according to the ECMA-74:2019 standard.
Up for anything
All Domane+ SLR models feature versatile 40mm tire clearance and road smoothing rear IsoSpeed so you can venture from smooth pavement to gravel roads with ease.
The new Domane+ SLR
Rigged for paved roads
Prefer pavement over pebbles? Domane+ SLR Shimano models are built with smooth and fast-rolling 32mm road tires and a road-specific 2x drivetrain.
Geared toward gravel
Like to take the road less traveled? Domane+ SLR SRAM models are built with gravel-specific components like capable 40mm gravel tires and a gravel-specific 1x drivetrain.
Nothing else like it
Most e-bike motors use gears and belts to move you forward – but gears and belts lash, slip, rattle, and wear out over time, which can disconnect you from your ride. The Trek Domane+ SLR uses a unique TQ harmonic pin ring transmission that’s not only smaller and lighter than traditional e-bike motors, but – because it has fewer moving parts – it’s also smoother, quiet, and more durable.
A faster ride at your fingertips
Easily switch between three modes of natural-feeling assist with discreet hood-mounted controls conveniently located right next to your shifters.
A sleek integrated display on the top tube provides live updates of your range, battery life, and speed.
