• The HSF Stem faceplate allows the Prole Design HSF/Aeria bottle to be fitted to our standard 1/Seventeen stem
• The HSF Aeria bottle smoothes airflow onto the frame, offering the chance to lower aero drag while increasing hydration carrying capacity
• The HSF Stem faceplate was designed to allow more riders to enjoy the speed advantage and convenience of the HSF Aeria bottle system – it is a simple upgrade to turn a normal bike into a superbike
