CHAPTER2 MANA GRAVEL HANDLEBAR

CHAPTER2 MANA-GRVL

Engineered for Gravel. Built for Adventure.

Purpose-built for the AO Gravel/Adventure platform, the MANA-GRVL is CHAPTER2’s answer to riders who demand performance, integration, and durability across the roughest terrain. While optimized for the AO, its universal 1-1/8” steerer tube compatibility makes it an excellent upgrade for other CHAPTER2 framesets like the RERE, TERE, and HURU, where cable routing is from the underside of the bar.

Performance Meets Precision

Crafted from 100% Toray® Uni-Directional Carbon, the MANA-GRVL combines optimal stiffness for sharp, confident steering with vertical compliance to absorb gravel vibrations and trail chatter. Every carbon layer—sourced and engineered in Japan—is strategically placed for strength, feel, and rider comfort.

With a 12° flare and a one-piece bar-stem construction, it delivers extra control and leverage, ideal for aggressive gravel descents and technical terrain.
