SPECS
The KAHA features fully integrated cabling via the MANA-GRVL Handlebar, Internal downtube storage compartment as well as a race ready and well balanced performance geometry.
The design brief for the KAHA was relatively simple, scratched onto the back of an envelope were the words “Controlled Speed”.
However, the journey to arrive at the perfect solution was anything but simple. We don’t want to skimp on practical details like storage, pannier/ fender racks, or ability to fit TT-Clip bars. Iteration after iteration, review after review, every little detail and decision was scrutinized to the nth degree.
Needless to say, all that effort was worth it, as the final deliverable achieves all the performance metrics we had envisioned for a High-Performance Gravel Racer.

MANA GRVL Aero Bar Innovation
The MANA-GRVL has been designed for the KAHA to optimise aerodynamics and enable integrated cabling.
The MANA-GRVL’s one-piece bar and stem construction features a 12º flare for tackling any gravel adventure you throw at it.
Made 100% from TORAY® Carbon and tested to EN ISO 4210:2014. The careful use of specific carbon lay-ups made in Japan creates just the right blend of stiffness for accurate and predictable steering yet enough “give” to take the sting out of any uneven road surfaces.
The MANA-GRVL is available in 6 size combinations so that you can dial in your desired position with effective stem lengths from 80-130mm and widths from 469-525mm.
Finally, with the adoption of trigger-happy electronic shifting and use of out-front GPS devices for those Strava® moments, the CHAPTER2 Bar + Stem combo comes ready to install Shimano® EW-RS910 bar end mounted Junction Box and Barfly® or K-Edge® style GPS mounts respectively.
