Chapter 2 recently unveiled its most stunning aero (UCI approved) and adjustable road frameset to date. The new KOKO frameset features Kammtail sections for aerodynamic gains and an adjustable seat clamp, where the rider can fine-tune for their intended ride feel. Chapter 2 is very confident the new KOKO is the fastest bike out there.

Chapter 2 KOKO — How aero are we talking about?

The new KOKO takes a lot of influence from its predecessor, the Chapter 2 Rere, which also takes advantage of Kammtail profiling.

The KOKO takes the Reres credentials and goes to the next level and has Kamm-Tail incorporated into the downtube, increasing the overall stiffness of the bottom bracket and headtube by 13.35% and 35.64%, respectively.

Air resistance is the single most critical factor that separates a fast bike from a super-fast bike (well that and the rider). The combo works seamlessly with the Chapter 2 ergonomic Mana bar; the addition of the bar makes for a  sleek, high-performance racing machine. It seems fitting as the word Koko means “to soar, fly” in Maori, and as the name suggests — this bike will have you flying.

Japanese carbon fiber by Toray

Each Chapter 2 carbon fiber frame is made from 100% Made in Japan Toray carbon. The process for the front triangle uses a Latex Mandrel for each size and ensures that the carbon wall thickness and resin flow are carefully controlled during production.

The bottom bracket and headtube junctions employ high-tensile directional Toray carbon to increase front triangle torsional stiffness.

Fully integrated and fast

Chapter 2 fully integrated the cabling and hydraulic hoses in the new KOKO, presenting a super clean visual look and keeping it slippery in the wind.

The fork crown blends with the headtube contributing to the seamless look with little pops of color for style.

When paired with Chapter 2s’ Mana one-piece bar combo, the KOKO levels up in aerodynamics. The Mana system uses a Quick-Fit spacer system to quickly adjust your fit without having to re-cable or disassemble the cockpit.

What about that adjustable compliance?

You can now dial in your compliance for your personal preference. The rider can do this by installing the aero Seatpost in the lower position (one of the two), increasing the cantilever action of the Seatpost by 8.5%.

The KOKO has two seat post compliance options

Standard position: This is the standard less compliant of the two. When in Position 1 (facing up), the compliance is regular. The KOKO still rides well in this position and will still glide over road chatter, but not as well as Position 2.
Increased Compliance: The seat clamp in position 2 (facing down) sets the comfort level to the maximum optimized compliance.

How does KOKO differ from the Chapter 2 Rere?

You can think of the KOKO as an all-out aero racing platform with the ability to deliver world-class handling and response — basically an upgrade over the Rere.

Additionally, the KOKO receives a service-friendly T47BB bottom bracket, differing from the press-fit BB86.5 of the Rere.

The Chapter 2 KOKO is a disc brake only with a 12 x 100mm front and 12 x 142mm thru-axle. The frameset is compatible with mechanical and electronic shifting groupsets. Those worried about stashing batteries fear not, the KOKO frame will easily fit both Di2 SM-BTR-2 and EPS V3 batteries. The tire clearance is a generous (for an aero road frame) 32mm and uses the T47 (86.5) threaded bottom bracket standard.

Soooo, what’s different about the seatpost, or is it the saddle clamp or is the the insertion point in the frame (fore vs aft)? How about an image of whats being explained and how it’s functionally different…
