Giant Propel Advanced Pro 0 Di2 Road Bike in Prismatic Haze

When the race is on the line and the bunch is together with a kilometre to go, the Giant Propel Advanced Pro 0 Di2 is exactly the kind of Giant road bike you want under you. Built to slice through wind and shed weight over the previous generation, it's a machine that's been engineered around one thing: going faster with less effort.

Features:

• Integrated aerodynamics: AeroSystem Shaping, developed through CFD analysis and dynamic wind-tunnel testing, has been optimised across every yaw angle. On open roads where the wind rarely comes straight at you, that matters more than most people realise. The truncated ellipse airfoil tube shapes and Contact SLR/SL Aero cockpit work together to produce the best overall aero performance in the Propel range, keeping drag to a minimum whether you're sitting in a group or out front on your own.
  
  
• Easier adjustability: all-new cable routing through the stem and head tube makes adjusting or swapping cockpit components considerably more straightforward than on older setups. For riders who like to fine-tune their position between events, or who are switching bars and stems between seasons, that's a welcome practical improvement that saves time and frustration in the workshop.
  
  
• Race-winning efficiency: advanced-grade composite frameset uses high-performance materials and Giant's proprietary manufacturing processes to come in lighter than the previous generation, with a stronger stiffness-to-weight ratio as a result. Shimano Di2 electronic shifting ties everything together cleanly, and on the Giant Propel Di2 the combination of an aero frameset and precise, reliable gearing makes for a bike that feels genuinely complete at this level.

The Giant Propel Advanced Pro Di2 sits just below the top-of-the-range SL 0 in the Propel family, but carries much of the same aero DNA at a more accessible price point. Across the full range of Giant road bicycles, the Propel line is the one to look at when speed and aerodynamics are the priority over all else.
