SuperB XC

The SuperB XC is intended to be a lighter, quicker design for XC and Marathon type races.  Still having ample frame bag and bottle cage capacity, the XC can run a shorter 490mm axle crown length fork, up to a 120mm suspension fork.  The bottom bracket is lowered, and the steeper head angle is in keeping with its intended purpose.
Keeping versatility in mind, the frame was designed to work as both a short travel or rigid bike for smoother trails, or as a technical singletrack racer with the longer suspension fork.  Head tube and seat angles remain in optimum ranges for both disciplines.  This design is one to consider for someone who is looking to consolidate perhaps a gravel bike and a trail bike into one machine.
The SuperB XC can run 29″ tires up to 2.6″, and 27.5″ tires up to 2.8″.  The recommended fork length is 490mm A/C, up to 120mm travel suspension fork.
