Domane AL 4 Gen 4

With a lightweight aluminum frame, clearance for larger tires, a 2x10-speed Shimano Tiagra drivetrain, top tube mounts, and an all-day road comfort geometry — Domane AL 4 is perfect for casual pedaling, group rides, fast commutes, and even venturing beyond paved paths to most gravel roads.

What do you get over the AL 2?

-A lighter weight 10-speed Shimano Tiagra drivetrain with a wider gear range for long days of riding in hilly terrain
-Shimano hydraulic disc brakes for stopping power in all conditions

Upgrade to the Domane AL 5 for a race-worthy 12-speed Shimano 105 drivetrain and an even wider range of gearing to tackle any road ride or light gravel ride.
