Dutchmann | The Vicious Cycle



On the cusp between form and function, The Vicious Cycle is a collaboration between retired frame-builder Duncan MacIntyre and composite specialist Anton Dekker, facilitated by Dutchmann. Partnering the characteristics of great design and functionality, South Africa’s most accomplished bicycle frame builder MacIntyre – whose work dates back to the early 70s for competitive brands and his own marquee label ‘Gemini’ – came out of retirement to collaborate with Dekker on the special limited edition of 10. Dekker runs a specialist composite workshop producing bespoke components for brands such as Porsche, Lamborghini and Ferrari. A collectors’ item for premium enthusiasts, The Vicious Cycle is hand built using original MacIntyre frames, Dekker Tri-spoke wheels and select contemporary components.


MacIntyre built the featured frame for SA Track Cyclist Malcolm Cochrane for competitive use in the Track World Championships in the mid 1980s and it was later used by SA Olympic contender Timothy Abbot. The hand-brazed frame is made from 653 Columbus steel tubing renowned for its impressive strength-to-weight ratio and flexing properties suitable for track racing. The frame was stripped and coppered by Gavin Oliver, provided with black lacquer detailing by Malcolm Sampson and rebuilt by Timothy Abbot using a range of classic and contemporary components including a 3T, Campagnolo, Vredenstein, Cinelli and Brooks.

The bespoke Tri-Spoke wheels were custom crafted for The Vicious Cycle project by Anton Dekker and his team at Exclusive Conversion using state of the art carbon fiber composites. The process includes the development of a custom mould and the hand-layering of 4 layers of composites & honey-comb to deliver the safety and performance requirements of a high performance rim. The Dutchmann rims are available as a separate order for front and rear use, with either a fixed gear hub or coaster (back pedal) braking hub and take a standard 700c tyre.




The Vicious Cycle logo was designed by Gustav Greffrath. Hand-drawn with purposeful reference to the hybrid classic/contemporary nature of the project, the logo speaks of movement, speed and craftsmanship.
