OVERVIEW
It's right for you if...
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 pedaling under the sun sound perfect and you need a bike that's comfortable enough to let you ride as long as you see fit.
The tech you get
A 100 Series Alpha Aluminum 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, 32mm tubeless ready road tires for added cushion, and flared handlebars for extra control and stability.
The final word
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.
