FlexTail is a technology designed to have a Flexible HardTail. This means that the tail of the frame is able to filter out small obstructions.

THE BERG TECHNOLOGY
Using a special mixture of 800 and 1000 toray carbon technology, the FlexTail is a fully engineered to the highest degree of precision and functionality. It’s hardtail riding reimagined.

HUMAN-CENTERED DESIGN
Tests have been performed with a ridersweight of 100kg to simulate the stroke of the FlexTail technology. This stroke resulted in a 6mm movement without damage to the rear chainstays.
LOW EMISSIONS & EFFICIENCY
The Frames are painted with a single shot clearcoat to reduce the environmental effect that painting causes. Did you know that some of our products don't have a clearcoat but an epoxy inside the carbon as a protective layer?
SIGNATURE DESIGN
We have developed an hardtail frame that shows the signature BERG line across the side of the frame.

REDUCED WIND IMPACT
Signature Aerodynamic shape that reduces the impact of side and front winds. From above these tubes are wider and flat to receive and extra push from back winds.
