Tri Stem Faceplate

The Tri Stem Faceplate lets a Profile Design HSF/Aeria or HSF/Aeroflow bottle mount to the standard Tri stem, smoothing airflow onto the frame so you can carry more fluid without adding drag. It fits the Tri stem only — not the 1/Seven — and Profile Design recommend a stem length of 80mm or more so the bottle clears the front brake.
