The Adrenaline GTS 21 is a stability road trainer using GuideRails to manage excess movement. It retains the GTS 20 support concept while extending DNA LOFT from heel to forefoot and pairing it with BioMoGo DNA for smooth cushioning and transitions. Engineered mesh with larger ventilation openings and a 3D Fit Print saddle balance airflow, stretch and hold. It is built for road training, including longer runs.
