Trek Checkpoint ALR Frameset

Trek Checkpoint ALR Frameset Overview

The Trek Checkpoint ALR Frameset is a gravel bike frameset built around a 300 Series Alpha Aluminum frame and a full carbon Trek Checkpoint fork. It gives riders a clean platform for a custom gravel frame build with internal cable routing, T47 bottom bracket standard, UDH, flat mount disc brake compatibility, and thru axle spacing.

The frame includes practical mounting points for gravel and adventure setups, including rack mounts, fender mounts, and integrated frame bag mounts.
