PRO DISCOVER STEM 10 Alloy Stem

Developed in Eindhoven, Netherlands, it reflects PRO’s Dutch engineering philosophy and is manufactured to Japan’s industry-leading standards. Its robust AL 7075 alloy construction pairs perfectly with Discover series alloy and carbon handlebars, delivering comfort, control, and performance.
