Overview
It's right for you if...
You’re looking for a high-end carbon e-road bike that's super light, super discreet, and super quiet. Versatility is important, and you want the ability to roll on everything from pavement to gravel. You also want the advantage of a quick and precise SRAM RED XPLR AXS previous generation wireless electronic drivetrain.
The tech you get
A lightweight 800 Series OCLV Carbon frame with rear IsoSpeed. A powerful 50Nm TQ harmonic pin ring motor that assists up to 32km/h, a 360Wh integrated battery, an integrated smart LED display, and discreet hood-mounted controls for toggling through assist modes. Aeolus Pro 3V OCLV Carbon wheels, previous generation SRAM RED XPLR AXS 1x12 wireless electronic drivetrain, carbon cranks, a vibration-absorbing Bontrager Pro IsoCore handlebar, and a RCS Pro stem that fully integrates your cables for a sleek look.
The final word
Domane+ SLR 8 AXS gives you the performance boost of our most discrete e-road system yet, with quiet, natural-feeling assist for cruising up climbs. It's paired with SRAM's previous generation RED AXS drivetrain for clean shifting, and carbon wheels to keep your whole ride supremely light.
Why you'll love it
- The TQ harmonic pin ring motor is impressively discreet, compact, light, whisper-quiet, and offers a powerful assist up to 32km/h
- The smart charge port, sleek integrated display, and discreet controls keep the bike looking and feeling like a traditional road bike
- Stable endurance geometry partners with road-smoothing rear IsoSpeed that absorbs bumps in the road for a smoother, more comfortable ride
- On long rides, you can add on a Range Extender that fits neatly in the bottle cage and gives you the power you need to go the extra distance
- You get upgrades where they matter most, like the wireless SRAM drivetrain and carbon wheels
"Undeniably fun to ride"
"Ultra-quiet, ultra-stealthy...like you’ve always got a hand on your back, or the feeling you get when you’re having a really, really (really) good day."

"Genuinely an all-new animal for road riding"
"Most ebikes have a very bottom-heavy feel… Domane+ SLR 9 doesn’t have any of these ride sensations. The fact that it feels more like a traditional road bike makes you want to push the limit in corners and on the flats...Feels like an acoustic bike on the open road, especially while corning and riding tight roads."

"One of the sleekest e-road options available"
"People looking at it from a slight distance, or even up close, probably wouldn’t know this is an e-bike...rear IsoSpeed decoupler, high-end OCLV 800 carbon material, endurance geometry, internal cable routing, and generous tire clearance that pushes this bike well into gravel territory."

"A leap forward"
"Feels smooth and natural on the road...descends confidently and feels agile…and it’s still comfortable like the regular Domane SLR."

"Lightweight, quiet and looks just like the regular version"
"If the holy grail for the best electric road bikes, or at least the path to greater acceptance, is to appear largely indistinguishable from regular road bikes, then Trek has seemingly made up serious ground."
