Festka Doppler Sigma Sports Exclusive Frameset (Inc ENVE Stem)

The Festka Doppler Sigma Sports Exclusive combines carbon fibre, titanium and a unique paint scheme to offer a truly stunning Frameset, with the performance to match.

The blend of materials offers a unique and engaging experience. The titanium provides a comfortable, refined and smooth ride, while the stiffness is greatly enhanced by the addition of carbon fibre at the most critical areas of the frame. Featuring an ultra-high modulus (UHM) carbon fibre construction, usually reserved for Formula 1 and the aviation industry, the seat tube, bottom bracket and headtube are phenomenally stiff, ensuring reduced flex and maximum transfer of power to the road.

Utilising ENVE's Road Fork, the handling is responsive and direct, while the premium carbon layup ensures high levels of comfort, effectively damping unwanted road feedback before it is transferred onto the riders wrists. Similarly, the custom painted ENVE Road Stem further enhances the ride quality and perfects the framesets already breathtaking aesthetics.

With a weight of merely 1150 grams, the Doppler is a popular choice with climbers, while the titanium tubing increases vertical compliance for a comfortable ride no matter the distance, gradient or terrain ahead. Featuring clearance for 25mm tyres and durable titanium dropouts, the Doppler is as versatile as it is aesthetically pleasing, and with a design ready to accept mechanical, EPS, Di2 and eTap Groupsets, you needn't worry about about the future-proofing of this high-performance frameset.
