The HSF Stem Cap allows the Profile 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. To this point it has required a specific stem – the new HSF Stem cap increases the options for access to the HSF Aeria technology.

The HSF Stem cap is only compatible with the 1/Seventeen stem (not the 1/Seven) and the HSF Aeria bottle. It is recommended to be used with stem lengths of 90mm and above in order to avoid interference with the front brake.
