A handlebar stem or bike stem is an essential component for the cockpit, and offers riders the opportunity to tweak their riding position. At Sigma Sports you'll find stems for road, gravel and mountain bikes from brands such as ENVE, Bontrager, Deda Elementi, PRO, Specialized, Zipp and many more.
Want to adjust your riding position or tweak your handling? A new bike stem can do just that. With a different stem length or angle, you can completely adjust your position on the bike, something popular with mountain bikers who prefer a shorter stem, which cuts down the reach and quickens the steering. Roadies may prefer a longer stem as it lengthens your reach which helps improve positioning for those long days in the saddle. Learn more about stems in our guide.
