Description
At CHAPTER2 we believe that cycling is one of the purest sports. Just you, your bike and a healthy appetite for adventure and suffering.
AO means “earth” in Maori. With the introduction of the AO we take you back to the essence of why you started cycling in the first place. Where you take it and how you ride it is all a matter of how you express yourself on a bike. Whether you are the gravel racing kind looking to put together a race inspired dream build or heading out with family and buddies for a journey cross country with panniers and ample bottles/cargo, the AO will suit your quest for speed, fun and adventure.
The dropped drive side chainstay and generously sized fork crown will allow you to make all those cool choices that matter for where you want to take the AO. The whole rig has been elegantly engineered to accept up to 47mm tires with 650B or 42mm with 700C, giving you numerous tire and wheel combos to suit each and every terrain you want to throw at the AO.
As with any new frame design project, the geometry is the foundation to an awesome ride. Using an extensive database of ergonomic data we were able to map out the ideal geometry that matches both the seasoned gravel racer and adventure seeker. The AO’s geometry has a linear stack and reach correlation from XS all the way to XL just like the human body.
Married to this balanced geometry is a beautiful form factor that elevates the whole experience, employing carefully selected Toray® T700 and T800 in specific locations throughout the frame and fork to achieve a ride quality that will add smiles to every hill you crest and every sand or gravel turn you throw the AO through.
With a frameset only offer, the AO offers endless choices for gear combos, whether you want 2X or 1X you make the call. With a 2X set-up you can fit up to a 50/34T chainring and if you are 1X minded, you can install up to 48T ring with or without the factory supplied chain guide so that you never have to worry about dropping the chain when hit that rugged terrain.
The whole package is finished off with a compliant 31.6mm carbon seatpost, a dropper post friendly external seatclamp, internal cabling and a matching stem and headset to create an elegant yet exhilarating ride.
