Trek Domane+ SLR 7 Metallic Red Smoke Red Carbon Smoke 2026 electric road bike

The Trek Domane+ SLR 7 Metallic Red Smoke/Red Carbon Smoke 2026 is a high-end electric road bike that combines performance and comfort thanks to its ultra-lightweight and stiff 800 Series OCLV carbon frame and rear IsoSpeed technology. Its quiet and compact TQ motor, featuring a pin-ring harmonic gear system, provides natural assistance up to 25 km/h. The 360 Wh battery, integrated into the down tube, preserves the bike’s aesthetics.

The Shimano Ultegra Di2 2x12-speed wireless electronic drivetrain ensures rapid gear changes. The rear IsoSpeed system and endurance geometry ensure optimal comfort. The Bontrager Aeolus Pro 37 carbon wheels optimise aerodynamics. The Trek Central app customises assistance modes and tracks performance data.

The frame’s 800 Series OCLV carbon offers an excellent weight-to-stiffness ratio. The Bontrager Aeolus Pro 37 wheels are lightweight and aerodynamic. The carbon handlebars and stem reduce weight and increase stiffness.
