Why We Love It

The Profile Design RZ3 Aero Bottle System is a smart upgrade for cyclists and triathletes looking to maximise hydration without compromising aerodynamics. Designed to sit cleanly within your bike frame, the RZ3 helps reduce drag while keeping fluids easily accessible during training rides, time trials, and long-course racing. 

 

Talk Nerdy To Me

The RZ3 uses a refined shape that complies with UCI regulations while enhancing overall integration with modern road and triathlon bikes. The 510ml BPA-free HDPE bottle features a squeezable construction for easy drinking and an opaque finish that allows quick visibility of fluid levels. An injection-moulded composite cage securely mounts to standard bottle cage bosses and has been redesigned to improve bottle retention.
