Profile Profile 1 / Seventeen St HSF Aer shaft cap

The HSF stem cover allows uncomplicated integration of the Profile HSF/Aeria tanks on our standard 1/Seventeen stem.

Performance

The HSF Aeria tank reduces air resistance on the frame while offering maximum comfort when feeding on the handlebars. Previously, a special stem was required for this system, from now on this sleeve will suffice.

Compatibility

Now only the HSF stem sleeve is compatible with a 1/Seventeen stem (not the 1/Seven) and the HSF Aeria hydration system. A stem length of at least 90 mm is recommended to avoid problems with the front brake. The HSF stem cap is designed to allow more riders to enjoy the speed benefits and comfortable solution of the HSF Aeria hydration system. A simple update to transform a bike into a high-end bike.
