The NOX Teocalli 27.5 is a lightweight, durable carbon rim designed for riders who want one wheel that can handle everything from everyday trail riding to XC riding and racing. Combining a generous 26mm internal width with a remarkably low 350g rim weight, the Teocalli delivers an excellent balance of speed, stiffness, and trail-ready durability.
Built around NOX’s asymmetric rim design, the Teocalli 27.5 features a 2.6mm offset to improve spoke tension balance and create a strong, laterally stiff wheel. The UniWeave™ carbon construction combines 3K and unidirectional carbon fibers for a lightweight structure engineered to withstand demanding trail conditions.
For additional impact protection, NOX equips the Teocalli with its RockGuard HL™ reinforced hookless bead. The wide, seamless bead is designed to improve durability against rock strikes and direct rim impacts, while the integrated Anti-Burp Bump™ helps with tubeless inflation and improves tire retention when running lower pressures.
At only 350 grams, the Teocalli 27.5 approaches XC-level weight while maintaining the durability expected from a true trail rim. It’s an excellent choice for riders looking to build a fast, responsive 27.5” wheelset that doesn’t need to be treated delicately.
