The frames

Our frames are made of  3AL/2.5v Titanium. We selected Titanium for its excellent fatigue and corrosion resistance, along with strength that will guarantee a CIRCA Bike’s place in history.
Whether you're riding a CIRCA Gravel, City Single, Cyclo-Cross or Road, the geometry and some design details will vary. CIRCA has a formula for frame layout to provide a great balance in providing exceptional performance and comfort, without conforming to rigid rules and expectations of the individual cycling disciplines.
