The HSG GRX Di2 is our core Shimano build, powered by the latest 1×12 GRX RX827 wireless groupset with a 10–51 cassette for an exceptionally wide gear range. It comes standard with a 40t or 42t GRX crankset, with upgrade options to Wolftooth chainrings (36–46t) or a boutique Garbaruk crankset.
Schwalbe G-One RX Pro tyres run tubeless on Pacenti Arch XC28 carbon rims (28 mm internal), delivering a strong, resilient and fast wheel setup ready for any terrain.
The build is completed with the full ENVE In-Route system—Aero stem, SES AR handlebar and carbon road seatpost—plus colour-matched Chris King components: Aeroset 3 headset, T47 bottom bracket and seatpost clamp.
