Lightweight design

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

Right for any road

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

Long-haul comfort

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

Pack it up, pack it in

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

Modern ergonomics, premium integration

A modern handlebar with 4cm 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.

High-value performance

Domane AL Disc is built in Trek's road race heritage, which means it's a road bike you won't outgrow as your rides get longer and faster.
