Trek Domane AL 4 Gen 4 Road Bike 2025 in Era White

The Domane AL 4 is a speedy and versatile road bike that’s a perfect starting point for anyone looking to get into road riding. With an Alpha Aluminium frame, clearance for larger tyres, a 10-speed Shimano Tiagra drivetrain, top tube mounts and an all-day road comfort geometry – Domane AL 4 is perfect for casual pedalling, group rides, fast commutes and even venturing beyond tarmac paths to most gravel roads.

You’re looking to venture into the world of road bikes and want one that’s comfortable, smooth and most importantly, won’t break the bank. You want to ride primarily on roads but also want a bike that can handle a rail trail or crushed gravel path, too. Days spent pedalling under the sun sound perfect and you need a bike that’s comfortable enough to let you ride as long as you see fit.

A 100 Series Alpha Aluminium frame with advanced tube shaping for high-end looks and ride quality, a 10-speed Shimano Tiagra drivetrain, powerful disc brakes for all-weather stopping, super-durable wheels, integrated frame mounts for carrying additional gear, 32 mm tubeless-ready road tyres for added cushion and flared handlebars for extra control and stability.

The Domane AL 4 is a true road bike and the perfect option if you’re just getting into riding. It’s comfortable for long days, quick enough to hang with the group and extremely versatile for when you’re ready to venture off road.
