Domane+ SLR 8 is a category-defining carbon high-power e-road bike that doesnt look, fit, or feel like a standard e-bike. Its built on an 800 Series OCLV Carbon frame that hides a compact and refined motor to elevate your ride with quiet, natural-feeling assist. You get a smooth boost for soaring up climbs and over long miles, plus clean shifting from SRAMs previous generation wireless 1x12 RED XPLR AXS drivetrain thats great for road and gravel alike.
- The TQ harmonic pin ring motor is impressively discreet, compact, light, whisper-quiet, and offers a powerful assist up to 28 mph
- 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
Compact, quiet, and mighty e-system
The TQ harmonic pin ring motor is super efficient with an amazing range-to-weight-to-speed ratio. Its ultra-compact, whisper-quiet, and offers an unbelievably natural-feeling assist up to 28 mph.
