Trek Domane AL 4 Gen 4

Domane AL 4 is the ideal road bike for those who want to go faster, farther, and on more varied terrain. The Alpha aluminum frame with endurance geometry prioritizes comfort without sacrificing responsiveness, making it perfect both for your first gran fondos and for long group training rides.

The 11-speed Shimano Tiagra drivetrain offers smooth shifting and a wide range of gears, so you can tackle demanding climbs and fast flat sections with maximum confidence. The new full carbon fork and the lighter frame design reduce weight by about half a kilo compared to the previous Domane AL Disc, improving acceleration, control, and comfort over long distances.

Thanks to the wide tire clearance and the top tube mounting points , the Domane AL 4 is ready for light bikepacking, rides on hard-packed gravel, and white roads. Stable, agile, and incredibly versatile, it’s the perfect road bike for anyone looking for a single solution for training, amateur racing, and adventures beyond the tarmac.
