Trek Domane+ SLR 9 eTap Electric Road Bike 2023
The Trek Domane+ SLR 7 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.
The perfect complement for a frameset of this calibre is SRAM's top-end wireless electronic groupset. SRAM RED eTap AXS keeps weight to a minimum, paired with carbon Praxis cranks, and delivers a smooth and almost instant shifting experience. The hydraulic RED brakes create confidence-inspiring stopping power in all conditions. Crank length, stem, handlebar and saddle are all frame-size specific, creating a more personalised ride feel for every rider.
The bike rolls on the fast, light and durable Bontrager Aeolus RSL 37V wheels fitted with Bontrager GR1 Team Issue Gravel Tyres so you're ready for any adventure or race on mixed terrain.
