Every Kestrel design is proprietary. Kestrel engineers everything in-house in Philadelphia, PA, beginning with computer-aided designed and analysis and ending with exacting manufacturing procedures and quality standards. While other companies order up a mass-produced, generic-design carbon frame from a nameless factory and slap their own stickers and paint on it, Kestrel engineers every Kestrel bike from scratch. The end result? Everything is monitored from the design to production, bringing to life what the engineers created and only what the consumer dreamed of.
