May 2, 2025 - Trek’s Domane+ SLR 9 looks like a traditional road bike, but hidden discreetly within the 800 Series OCLV Carbon frame that features rear IsoSpeed is a near-silent 250W TQ HPR50 harmonic pin-ring mid-drive motor with 50Nm of torque and powerful pedal assist up to 32kph. The system pairs with an integrated 360Wh battery to provide up to 100km of range with an optional 160Wh range extender. A Shimano Dura-Ace Di2 12-speed drivetrain can be customized via the Shimano E-Tube app. Bontrager tubeless-ready 32mm tires are mounted on Aeolus Pro 37 carbon wheels, but the frame can accommodate up to 40mm tires allowing for more versatility.
