TREK Domane+ SLR 9
Our finest high-speed assist carbon e-road bike that doesn’t look, fit, or feel like a standard e-bike is the Domane+ SLR 9. It has a frame made of 800 Series OCLV Carbon that conceals a small, sophisticated motor that will enhance your ride with a natural-feeling assist. On calm solo spins and club rides, the motor blends in with the environment so well that it almost completely vanishes under you, allowing you to stay more in the moment while still having enough power for challenging climbs and protracted, epic excursions. The cherry on top is that it boasts the highest-quality components the market has to offer, such as Dura-Ace Di2, Shimano’s top wireless electronic drivetrain.
It is appropriate for you if…
You’re looking for the best and lightest carbon e-road bike available. You want a motor that is both discreet and quiet, while still providing the support you want on steep climbs and long days in the saddle. You value versatility, and you require a bike that can handle everything from smooth roads to hard gravel grinds. You value finer things and want the best performance improvement possible, such as Shimano’s top wireless electronic drivetrain.
The technology you receive
Our lightest and best-performing 800 Series OCLV Carbon frame with rear IsoSpeed. A strong 50Nm TQ harmonic pin ring motor that can assist at speeds of up to 28mph, a 360Wh integrated battery, an integrated smart LED display, and discreet hood-mounted controls for switching between assist modes. Shimano Dura-Ace 2×12 Di2 wireless electronic drivetrain, carbon cranks, a vibration-absorbing Bontrager Pro Iso-Core handlebar, and an RCS Pro stem that totally integrates your wires for a sleek aesthetic are all features of the Aeolus RSL 37 OCLV Carbon wheels.
The last word
The Domane+ SLR 9 is our best e-road bike. The OCLV Carbon frame and discreet TQ drive system provide the extra boost you need without sacrificing sleek looks or performance. Furthermore, Shimano Dura-Ace Di2 delivers ultra-fast and precise shifts every time.
