KOGA Kimera Carbon 3K Di2
Lightweight FEM optimized carbon frame. Built with
Highmodulus carbon fiber and finished with a durable 3k carbonfiber mesh.
Equipped with Koga's Powertrain Technology, Tapered head tube with integrated 1
1/8"-1 1/4" headset. Integrated cable routing, Press-Fit bottom
bracket, Carbon dropouts and a replaceable rear derailleur hanger.
Front fork: Full carbon 3k woven.
Using advanced computer calculations (Finite Element Analysis) the ideal fibre
orientation for each of the carbon layers has been determined. This method
allows us to achieve an optimal stiffness-to-weight ratio.
Koga's Powertrain Technology
The flowing transition from top tube to the seatstays gives the frame high
rigidity and guarantees that forces applied by the rider are transferred
perfectly to the rear wheel.
Tapered head tube
The lower headset bearing is of a larger diameter (1 1/4") than the top
one (1 1/8”). The larger fork dimensions create a more rigid fork, with more
stable steering characteristics for the same weight.
Integrated cable routing
All the brake and shifter cables are fully integrated into the frame.
Press-Fit bottom bracket
The bottom bracket bearings are pressed into the frame: this saves weight and
provides improved rigidity, because the downtube can be made with a larger
diameter where it connects to the bottom bracket.
The dropouts on both frame and fork are made in carbon, giving low weight and
assuring the best possible connection to the rest of the frame. The aluminium
derailleur hanger can be easily replaced in the event of damage.
