THM Tibia Road ICR Carbon Stem

The Tibia ICR Carbon Road Stem elevates precision road performance with internal cable routing compatibility and world-class lightweight construction. This stem is one of the lightest in the world, tipping the scales at approximately 90 g for the 100 mm length

Constructed entirely from carbon fiber using THM’s proprietary layup and carbon molding process, the Tibia ICR delivers elite stiffness while absorbing vibration for smoother, more controlled steering. Its four-bolt faceplate ensures even clamping force, reducing stress on handlebars and enhancing structural integrity.

THM reinforces its reputation for top-tier engineering: all stems, bars, and combos are 2024 ICR-ready, meaning the Tibia can be configured for either D‑shaped or standard headset exit routing depending on frame design. The stem remains one of the stiffest and strongest in its ultralight category and even holds an MTB approval for the 80 mm length
