You're looking to venture into the world of road bikes and want one that's fast, smooth, and comfortable, and won't break the bank.

Days spent pedaling under the sun sound perfect and you need a bike that is comfortable enough to let you ride as long as you see fit.

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.
