Trek Domane+ SLR 9 Electric Road 5274702 2025

Trek Domane+ SLR 9 Electric Road Bike 2025 The Trek Domane+ SLR 9 Electric Road Bike redefines e-bike technology; a compact motor is subtly incorporated into the frame and it runs extremely quietly so you get all the benefits of an extra boost without any drawbacks. The complete build only weighs around 12kg, size-dependent, and this is down to the lightweight harmonic pin ring e-system motor and advanced 800 Series OCLV frame construction. A 360Wh battery sits neatly within the downtube, delivering an excellent 60-mile range that can be stretched to 90 miles if a Range Extender is added, and the pedal-assisted boost is provided up to 25kph (15.5mph). Using the Trek Central app, you can customise the system to suit your needs. Intuitive mode control buttons are easy to access on the hoods, with the user interface sitting neatly on the top tube in clear view. The frameset is designed with Trek's Endurance Geometry, which is a little less aggressive than the most extreme race bikes, and this makes for a stable yet still lively ride. IsoSpeed in the rear helps to smooth out bumps and this, together with the wide tyre clearance, makes for more comfortable all-day riding.  Shimano's top-drawer Dura-Ace Di2 groupset is the ideal complement. The 2x configuration with compact chainrings and a wide-ranging cassette creates plenty of gears for hills, descents and fast flats alike. Hydraulic braking takes care of stopping, both on dry and wet roads. Crank length, stem, handlebar and saddle are all frame-size specific, creating a more personalised ride feel for every rider. The bike rolls on strong, stiff Bontrager Aeolus RSL 37 tubeless-ready wheels fitted with Bontrager R3 Hard-Case Lite tyres in a 32mm width for effective shock absorption, fast rolling and traction.
