The HSR Shimano Dura Ace Di2 is our flagship Shimano build, combining wireless Dura Ace ergonomics with the precise, immediate shifting of the top-end groupset. Cassette options (11–30, 11–34, 11–36) paired with 50/34, 52/36, or 54/40 chainrings provide a wide, tightly spaced gear range for any terrain.
Continental Archetype 30mm or Continental GP5000 S TR tyres run tubeless on Scandalous Carbon Collective Ultra 38, 50, or 60 wheels (24mm internal, ceramic bearings) for a light, responsive, and fast setup suitable for mountains, fast roads, or group rides.
The hand-built Columbus Spirit frame integrates the Trittico Trefoil fork, stem, handlebar, and seatpost for stiffness, adjustability, and style. Colour-matched Chris King T47 bottom bracket, Inset 7 headset, and seatpost clamp complete the premium build.
