Trek Domane AL 5 (Gen 4) Performance Road Bike 2027

Domane AL 5 is a smooth, capable road bike built for riders who want performance without sacrificing comfort. Its Alpha Aluminum frame pairs with a 12-speed Shimano 105 drivetrain for precise shifting and a wide gear range. All-day geometry keeps you comfortable on longer rides, while bigger tire clearance and top tube mounts add versatility for light gravel, gear, or daily commutes.
