Confirm replacement component standards, tire clearance and the actual build with Go Grava before changing wheels, tires, drivetrain or cockpit parts.

The AD9 is built like a true flagship race machine. The included power meter saves a major upgrade cost most brands leave for later, and the Branta carbon wheelset with carbon spokes puts this bike directly against bikes that typically retail for significantly more. This is the kind of bike where proper initial fit, torque setup, and Di2 setup matter from day one. We strongly recommend professional fit confirmation before final delivery.

• Best for aero road racing, fast group rides, triathlon prep, and high-speed climbing
• Good for riders who already know their fit numbers and riding position preferences
• Excellent value compared to other Dura-Ace Di2 superbikes in the $12k+ category
• Less ideal for casual fitness riding or frequent fit experimentation
• Best when purchased with professional sizing guidance due to integrated cockpit limitations

Good Fit: Strong riders, racers, triathletes, and performance-focused road cyclists looking for a true aero race platform with elite-level spec. Ideal for riders who want Dura-Ace Di2, integrated power data, and carbon wheel performance without paying traditional superbike pricing.

Not A Fit: Not ideal for riders prioritizing comfort-first endurance geometry, relaxed fit, or heavy all-road use. Not a good fit for riders who frequently change stem length or handlebar width since the integrated cockpit limits quick fit changes. Not ideal for beginners still figuring out aggressive road positioning.

This is a full aero race bike with integrated routing and an aggressive front-end. Fit matters. Integrated cockpits are clean and fast, but sizing mistakes are more expensive than traditional bar/stem setups. The T47 bottom bracket is a major positive for serviceability compared to many press-fit systems. UDH compatibility also helps future hanger support and replacement.

Components can vary by production batch; confirm the actual bicycle before selecting replacement parts.

Manufacturer rider-height ranges are a starting point, not a fit guarantee. Confirm your fit with Go Grava, especially between sizes. Measurements are shown in cm and mm.
