Trek Domane+ SLR 7 eTap Electric Road Bike 2023
The Trek Domane+ SLR 7 eTap 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.
Thanks to the ability to fit the Domane+ with tyres up to 40mm, and its stable ride feel, this bike is well suited to both on and off-roading. Rolling on Bontrager Aeolus Pro 3V carbon wheels and Bontrager GR1 Team Issue Gravel Tyres, you can set up tubeless and hit gravel tracks and trails in complete comfort, with confidence-inspiring traction and puncture protection. The 1x wireless SRAM Force eTap AXS drivetrain is adventure-ready and delivers fast, smooth electronic shifting and powerful hydraulic braking.
