TEMPO ARGO R3 is a versatile endurance road saddle with a short-nose design and generous ischial support that encourages stability. Where a traditional saddle shape encourages riders to shift their position frequently for better leverage, Argo puts the rider in a more planted position, making for greater stability and better weight distribution.
