Trek Domane AL 2 Gen 4
Trek / Performance Road Bikes
Ride farther. Feel better doing it.
Domane AL 2 is a lightweight road bike built for new riders who want speed, versatility, and confidence on the road. It features an Alpha Aluminum frame, an 8-speed Shimano Claris drivetrain, and a comfortable all-day geometry that’s great for group rides, fitness riding, or fast commutes. Rack, fender, and top tube mounts add everyday utility, and clearance for larger tires means you can venture off the pavement onto light gravel.
Based on the bike's size chart. Your complimentary baseline fit in store dials in the rest.

Questions are welcome. No pressure, no bike jargon required.
The ride, not just the specs
Domane is the road bike for real roads: rough pavement, long days, and rides where you want to feel good at the end, not just fast at the start.
It's comfortable, capable, and ready for the century you keep talking about.
What makes it special
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 tires let you ride everything from smooth pavement to most gravel roads in comfort.
A more upright road riding position keeps you comfortable, confident, and efficient during long days in the saddle.

“Credibility both on road and on dirt”
Added capability makes the Trek Domane AL a worthwhile choice for someone looking to dabble in both road bike and gravel bikes. While the bike is still a road bike at heart, its features make it capable enough to ride lighter gravel frequently [...] The gravel bike tire clearance, mounts for racks and fenders, and full carbon fork are nice upgrades to a bike that I think will make a lot of people happy.

“Most bang for the buck”
The frame is aluminum, the fork is carbon, and the accessory mounts are plentiful, meaning this bike can do much more than a local fondo.
