Deda ADJ Adjustable Stem
The Deda ADJ is an adjustable stem designed to help riders find the optimal riding position. It is also widely used by professional team mechanics when setting up time trial and triathlon bikes, allowing precise evaluation and fine-tuning of rider position.
Unlike workshop-only fitting tools, the Deda ADJ can be installed directly on the bicycle and tested on the road or track, making it easy to adjust and refine your position under real riding conditions. The stem offers a wide adjustment range from +30° to -40°, providing excellent flexibility for handlebar height and reach setup.
