American Custom Bicycles in Steel, Titanium and Ti/carbon mix
Mixed-Terrain Bike: The Sentinel is an agile, all-out gravel bike that incorporates our chopped chainstays, curved seat tube and moto seat stays to make it the most maneuverable dirt grinder in any rider&rquo;s arsenal.
Supreme traction is fed by its custom geometry and multi-directionally compliant seat stays (Yes! Multi-directionally compliant!!). It is 1x optimized and wears a 700c x 38 knobby stock tire. It comes with a Chris King headset, and our best in class Matador gravel fork.

Popular perception is that chainstay length is one of the most important factors in bike design because stay length affects bike handling, acceleration, climbing speed, and descending stability. With more than 30,000 custom bikes designed and built, we think Seven brings unique experience to each new bike project. Find out how.
