Why We Love It

For triathletes and cyclists relying on liquid nutrition, the Profile Design HSC 250 Top Tube Flask delivers a smarter fuelling solution. Designed to sit neatly behind the stem, the flask integrates cleanly with your bike setup, helping create a streamlined cockpit that's ideal for long-course triathlon, time trials, and endurance cycling.

 

Talk Nerdy To Me

The HSC 250 features a 290ml BPA-free HDPE flask designed specifically for carrying concentrated liquid nutrition. Mounted directly to compatible top tube bosses, or via an aftermarket FPS kit, the flask sits low and protected behind the stem for minimal aerodynamic disruption. Its unique front shell design allows cables to route cleanly through the system, helping maintain an aero profile on modern bikes. The soft, squeezable construction makes consuming nutrition simple while riding, and the integrated cage shields the nozzle from sweat and road contamination to help keep your nutrition clean throughout your ride.
