Trek Domane AL 2 Gen 4 Road Bike – Crimson / Dark Carmine Fade

The Trek Domane AL 2 Gen 4 is the perfect entry point into the world of road cycling — fast, comfortable and incredibly versatile. Whether you’re joining weekend bunch rides, commuting through the city, or exploring smooth gravel paths, this bike is built to make every ride feel smooth and confidence-inspiring.

At the heart of the Domane AL 2 is Trek’s lightweight 100 Series Alpha Aluminium frame, paired with a carbon fork that absorbs road vibration and keeps handling precise. The geometry is designed for all-day comfort, giving new and returning riders a more relaxed position without sacrificing speed. It’s a bike that feels quick when you push it, but forgiving when you’re just cruising.

The Shimano Claris 8-speed drivetrain offers reliable, easy-to-use shifting and a wide gear range that handles rolling hills and flat sprints with ease. Mechanical disc brakes provide dependable stopping power in all weather conditions — ideal for year-round riding and urban commuting.

One of the Domane AL 2’s biggest strengths is its versatility. With clearance for wider tyres, plus rack, mudguard and top-tube mounts, you can easily set it up for commuting, fitness rides, or light gravel adventures. Out of the box, the Bontrager 32mm tyres strike a great balance between speed and comfort, smoothing out rough roads and bike paths.

Finished in a striking Crimson / Dark Carmine Fade, this Domane stands out visually while delivering the performance and durability Trek is known for. It’s a bike designed to grow with you — from your first serious road ride to long weekend kilometres and beyond.

Size Guide

How tall are you?

To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inside leg?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
