4130 chromoly construction
The hand-built 4130 chromoly chassis delivers the smooth, lively ride feel associated with the Sirius. Its durable steel construction offers a more affordable alternative to the titanium version.
Drop Optimized Geometry®
The CrMo shares its award-winning geometry with the Sirius S6 Titanium. It is designed for both trail riding and fully loaded bikepacking, with options for 29-inch, 27.5-inch or mullet wheels.
Repairable steel
Chromoly steel makes the frame field-repairable. If repairs are needed, a framebuilder can work on the material, helping keep the frame in use.
