You’re after the best and lightest carbon e-road bike you can find. You want a motor that's super discreet, super quiet, and offers the support you crave on steep climbs and long days in the saddle. Versatility matters to you, and you need a bike that can handle everything from smooth roads to rough gravel grinds. You appreciate the finer things, and want the performance upgrade of the best possible components, like Shimano’s top wireless electronic drivetrain.
The tech you get
Our best and lightest 800 Series OCLV Carbon frame with rear IsoSpeed. A powerful 50Nm TQ harmonic pin ring motor that assists up to 28mph, a 360Wh integrated battery, an integrated smart LED display, and discreet hood-mounted controls for toggling through assist modes. Aeolus RSL 37 OCLV Carbon wheels, Shimano Dura-Ace 2x12 Di2 wireless electronic drivetrain, carbon cranks, a vibration-absorbing Bontrager Pro Iso-Core handlebar, and a RCS Pro stem that fully integrates your cables for a sleek look.
The final word
Domane+ SLR 9 is the best e-road bike in our lineup. The OCLV Carbon frame and discreet TQ drive system give you the added boost you want without sacrificing sleek looks and impressive performance. Plus, Shimano Dura-Ace Di2 delivers ultra fast and precise shifts every single time.

- The TQ harmonic pin ring motor is impressively discreet, compact, light, whisper-quiet, and offers a powerful assist up 28mph
- 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
- It comes equipped with a 2x Shimano drivetrain and fast 32mm tires for the pavement, but can fit up to 40mm tires when you want more off-road versatility
"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."
