Trek Domane AL 2 Gen4 (2026)

A new full carbon fork and updated frame design helps shave around half a pound from the previous generation Domane AL Disc.

Room for bigger tyres let you ride everything from smooth tarmac to most gravel roads in comfort.

A more upright road riding position keeps you comfortable, confident and efficient during long days in the saddle.

Mounts for a top tube bag, rack, mudguards and water bottles let you carry everything you need for day-long adventures, fast commutes and anything in between.

A modern handlebar with 4 cm of flare between the drops and hoods put you in a more comfortable position, and new hidden cable routing offers premium integration typically found on more expensive models.
