Trek Domane AL 2 Gen 4 Overview

The Trek Domane AL 2 Gen 4 is a gravel bike built with a 100 Series Alpha Aluminum frame, Domane AL carbon fork, and Shimano Claris 8-speed drivetrain. Its frame includes internal routing, fender mounts, flat mount disc compatibility, UDH, and a 142x12mm thru axle. The carbon fork uses a tapered carbon steerer with internal brake routing, fender mounts, flat mount disc fitment, and a 12x100mm thru axle.

The drivetrain uses Shimano Claris shifters with a Shimano Claris front derailleur and Shimano Claris long-cage rear derailleur. A Shimano RS200 50/34 compact crankset pairs with an 11-32, 8-speed Shimano HG31 cassette for a straightforward 2x setup.

For braking, the bike uses Tektro C550 mechanical disc brakes with dual-piston flat mount calipers and 160mm Tektro 6-bolt rotors. The wheel setup includes Formula alloy hubs, Bontrager Paradigm SL Tubeless Ready rims, 14g stainless steel spokes, and Bontrager R1 Hard-Case Lite 700x32mm tires. Finishing parts include a Verse Short saddle, Bontrager Comp alloy seatpost, Bontrager alloy handlebar options by size, Bontrager Supertack Perf tape, and a Bontrager Elite Blendr-compatible stem.
