When we’re building a race-ready triathlon cockpit, clean integration is everything. The Tri Stem from Profile Design is engineered to simplify front-end setup while maximizing aerodynamic efficiency and hydration compatibility. Forged from 6061-T6 aluminum, the stem delivers stiffness and reliability in an aggressive -17. 5° angle suited to performance-focused positions. Designed to accommodate both top tube and headset cable routing, it helps create a streamlined, clutter-free cockpit. The integrated HSF faceplate allows direct mounting of compatible hydration systems like the HSF/Aeria bottle, keeping fluids accessible without disrupting airflow. Available in 80mm and 105mm lengths, and built around a 31. 8mm clamp with 1-1/8in steerer compatibility, the Tri Stem is a refined solution for modern triathlon and time trial builds seeking aerodynamic integration and practical versatility.
