Frame and Fork

Frame: The foundation of this bike is the 500 Series OCLV Carbon frame, Trek’s premium lightweight laminate . It features the signature Domane endurance geometry, which prioritizes stability and comfort for long days in the saddle . The frame is equipped with both front and adjustable rear IsoSpeed, a decoupler system that allows the seat tube to flex independently, effectively absorbing road vibrations and smoothing out rough pavement for a less fatiguing ride . The frame is meticulously designed to integrate the Fazua drive system, keeping the motor and battery hidden within the downtube for a clean, stealthy aesthetic . It also features internal cable routing, flat-mount disc brakes, and a 148x12mm thru-axle .
Fork: The matching Domane SL carbon fork features a tapered carbon steerer for precise steering and internal brake routing . It’s designed with the same endurance-minded geometry and includes fender mounts for added versatility .
Project One Customization: As a Project One bike, this Domane+ LT features a unique, owner-selected paint scheme that sets it apart from standard production models, making it a true one-of-a-kind .

Motor and Battery

Motor: The bike is powered by the innovative Fazua Evation drive system . This mid-drive motor delivers a natural and intuitive 250W of power (max 400W peak) with 60Nm of torque, providing assistance up to 25 km/h (15.5 mph) . It features three assistance modes accessible via a sleek, integrated top tube button with LED indicators: Breeze (a gentle, constant 100W tailwind), River (a demand-responsive mode up to 210W), and Rocket (a more powerful, steeper power-curve mode up to 250W) . The motor is renowned for its smooth, linear power delivery and near-silent operation .
Battery: A fully integrated 250Wh Fazua Evation battery is discreetly housed within the downtube, contributing to the bike’s clean lines . It offers a real-world range of approximately 60-80 km (37-50 miles) or up to 1,200 meters of elevation gain on a single charge, depending on the assistance mode and terrain .
Removable System: A key feature of the Fazua system is its full removability. The entire motor and battery unit can be easily taken out of the frame, and a replacement cover can be installed (sold separately), effectively converting the e-bike into a conventional, non-assisted road bike weighing as little as 10.7 kg .

Drivetrain

Shifting: The bike is equipped with the crisp and reliable Shimano Ultegra R8020 2×11-speed mechanical groupset . The shifters are ergonomically refined and integrated with the hydraulic brake controls.
Derailleurs: The Shimano Ultegra R8000 front derailleur (braze-on) and Shimano Ultegra R8000 GS rear derailleur (long cage) deliver precise and dependable shifting performance across the wide gear range .
Crankset: Power is transferred through a custom FSA alloy crankset, designed specifically for the Fazua system, with a compact 50/34T chainring combination . For the 56cm frame, the crank arms are sized at 172.5mm to ensure an optimal fit .
Cassette & Chain: The wide-ranging Shimano Ultegra HG800-11 11-34T 11-speed cassette provides the gearing needed to conquer steep climbs, paired with a durable Shimano Ultegra HG701 chain .

Brakes

Confident and consistent stopping power comes from Shimano Ultegra R8070 hydraulic disc brakes . These brakes offer excellent modulation and reliable performance in all weather conditions. They are paired with 160mm centerlock rotors, providing ample stopping force for confident descending, even with the added weight of the e-bike system .

Cockpit and Finishing Kit

Handlebar & Stem: The cockpit features a Bontrager Elite IsoZone VR-CF alloy handlebar, which includes IsoZone dampening material in the drops to reduce road vibration . For the 56cm frame, the bar width is 42cm . It’s paired with a Bontrager Pro stem (31.8mm, 7-degree rise), sized at 100mm for the 56cm to ensure a proper, stable fit, and is Blendr-compatible for a clean accessory mount .
Seatpost: A Bontrager carbon internal seatmast cap with an integrated rear light mount is used, contributing to the bike’s aerodynamic and clean look . For the 56cm frame, the “short length” mast cap is typically used .
Saddle: Comfort is provided by a Bontrager Arvada Comp or Elite saddle (depending on the final Project One spec) with steel or stainless steel rails, designed for all-day riding performance .
Integrated Lighting: A notable feature is the inclusion of integrated front and rear lights, powered by the main battery, enhancing safety and visibility for commuters and endurance riders .

Wheels and Tires

Wheelset: The bike rolls on a durable and reliable DT Swiss G1800 wheelset . These alloy rims are tubeless-compatible, 25mm deep, and feature 12mm thru-axles (front 100mm, rear 148mm) for stiffness and security .
Tires: It is fitted with fast-rolling and grippy Bontrager R3 Hard-Case Lite tires in a 700x32c size, offering excellent puncture protection and a supple ride . The frame has generous clearance, officially supporting tires up to 38mm, which allows for light gravel and all-road adventures .
