The Trek Domane+ SL 9 AXS combines discreet electric assistance with a lightweight carbon endurance road platform. Its compact TQ drive system provides subtle support that works alongside your own effort, helping take the edge off climbs and longer rides while maintaining the natural feel of a road bike.
The TQ-HPR40 motor delivers up to 40Nm of torque and 200 watts of peak power. Its compact design allows the drive system to integrate neatly into the frame, helping the Domane+ retain balanced handling and a clean appearance. The motor is powered by an integrated 360Wh TQ battery.
A TQ colour LED display provides key ride and assistance information without adding a bulky screen to the cockpit. Bluetooth and ANT+ connectivity also allow the system to communicate with compatible devices.
The 500 Series OCLV Carbon frame is designed around the TQ drive system, combining low weight with the comfort and efficiency expected from an endurance road bike. A tapered head tube and 12mm thru axles contribute to precise handling, while internal routing keeps the overall finish clean.
Up front, the Domane+ carbon fork uses a tapered carbon steerer and 12x100mm thru axle for predictable steering. Internal brake routing maintains the uncluttered appearance, while integrated mudguard mounts on the frame and fork add useful versatility for year-round riding.
SRAM RED XPLR AXS brings premium wireless electronic shifting to a simple 1x13-speed drivetrain. The 10-46T SRAM XG-1391 cassette provides a broad gear range for changing gradients, while removing the front derailleur keeps gear selection straightforward.
SRAM RED AXS hydraulic disc brakes provide powerful and controlled stopping performance. SRAM Paceline X 160mm rotors are fitted front and rear, giving consistent braking and plenty of modulation for managing speed smoothly on longer descents and in changing conditions.
Bontrager Aeolus RSL 37 carbon wheels combine a relatively shallow 37mm profile with lightweight carbon construction, balancing aerodynamic efficiency with responsive handling. They're paired with Bontrager Kwaremont RSL 700x35mm tubeless-ready tyres, featuring a supple 320 TPI casing and GR puncture protection.
The 35mm tyres add useful volume for comfort and grip over rougher roads, while clearance for tyres up to 40mm gives you scope to tailor the bike towards even greater comfort or mixed-surface riding. This versatility makes the Domane+ equally at home on smooth tarmac, broken back roads and routes incorporating light gravel.
A Bontrager Pro carbon riser bar adds 20mm of rise, helping create a comfortable position for long days in the saddle while keeping weight down. The separate Trek RCS stem also retains useful cockpit adjustability.
A 27.2mm Bontrager RSL carbon seatpost adds compliance to help reduce road chatter and is paired with a Verse Short Pro saddle with carbon rails, further supporting the bike's balance of low weight and long-distance comfort.
Integrated frame bag and mudguard mounts make it easier to carry essentials or adapt the bike for changing weather. UDH compatibility also makes replacement derailleur hangers easier to source.
With its TQ-HPR40 drive system, SRAM RED XPLR AXS drivetrain and Aeolus RSL 37 carbon wheels, the Domane+ SL 9 AXS is a premium option for riders who want discreet electric support without losing the responsive, comfortable character of an endurance road bike.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimeters for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but is like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the e mountain bike column.
