Road endurance
Trek Domane AL Gen 4
2024 · 700c wheels · 7 sizes
Trek's alloy endurance road bike, with a 100 Series Alpha aluminium frame and a carbon fork. The Domane AL 2, AL 4 and AL 5 Gen 4 share this geometry. Stock parts listed are from the Domane AL 4 Gen 4 build. Trek uses two fork offsets across the range: 53 mm on the 44 to 54 cm frames and 48 mm on the 56 to 61 cm frames. On the 44 cm frame, Trek's published effective top tube is a few millimetres longer than its reach, stack and seat angle imply.
