The HSR Shimano Ultegra Di2 is our second-tier Shimano build, offering Dura Ace trickle-down technology for fast, precise shifting with semi-wireless functionality and ergonomic levers. Cassette options (11–30, 11–34, 11–36) paired with 50/34 or 52/36 chainrings provide a wide, tightly spaced gear range for any ride.
Continental GP5000 STR tyres run tubeless on Scandalous Carbon Collective Ultra 38, 50, or 60 wheels (24mm internal, ceramic bearings) for a light, responsive, and fast setup across all terrains.
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.
