The stem sets your position on the bike — length and rise determine your reach and stack, and getting those numbers right matters more than almost any other fit variable. Stems at RA Cycles covers 176 products across road, gravel, mountain, track, and triathlon setups: standard aluminum options for everyday riding, carbon stems for weight-conscious builds, aero-profile stems for riders focused on frontal area, and internal cable-routing stems for clean cockpit builds.

The range spans from entry-level alloy through to flagship carbon pieces from THM, Look, ENVE, FSA, and Lemond — with options from Deda, MOST, 3T, PRO, Easton, and more. Whether you’re dialing in fit, reducing weight, or cleaning up a cable run, the selection here covers every discipline and most major handlebar interface standards.

About Stems

Stem selection is fundamentally a fit decision. Length affects your reach — shorter stems bring you upright and increase responsiveness; longer stems extend your position and favor aerodynamics over sustained efforts. Rise angle determines stack height, which shifts how much weight lands on your hands and how open your riding position feels. Beyond fit, material affects ride character: aluminum is durable and cost-effective across the full range; carbon saves meaningful weight and can take the edge off road vibration on longer rides.

RA Cycles stocks stems across every discipline and material. At the premium end, THM’s Tibia stem represents the extreme of what carbon manufacturing can achieve in terms of weight. Look’s aero stems are built around frontal area reduction for road and track applications. ENVE covers both road and mountain with carbon construction throughout. FSA offers a broad range from aluminum options through to full carbon internal-routing stems for integrated cockpit builds. Deda, MOST, 3T, PRO, and Easton round out the range across road and gravel setups.
