Trek Domane AL 4 Gen 4 Endurance Road Bike
The Trek Domane AL 4 Gen 4 is a versatile endurance road bike built for riders who want to go faster and farther with comfort and confidence. Its lightweight Alpha Aluminum frame uses all-day geometry to keep you stable on long rides, rougher roads and mixed-surface detours. The new frame and full carbon fork help reduce weight by around half a pound compared to the previous Domane AL Disc, improving efficiency and handling.
The Domane AL 4 pairs the updated frame with an 11-speed Shimano Tiagra drivetrain for smooth shifting and a wider gear range than entry-level builds. Larger tyre clearance and confident handling make it suitable for long group rides, fitness miles and adventurous gravel shortcuts. Top tube mounts add practical storage options for bags and accessories, and mudguard mounts keep the bike ready for all-weather riding.
The carbon Domane AL fork uses a tapered steerer, internal brake routing and a 12×100 mm thru axle for precise steering and improved stability. The frame includes flat-mount disc brakes and fender mounts for year-round versatility.
