Frame materials
Koga stands for absolutely top quality. Painstaking tests in our own test centre ensure that our technical innovations deliver what they promise in real world use. So Koga offers a lifetime guarantee on its frames, with the exception of carbon frames, for which the guarantee is 10 years.
Chrome-Molybdenum
A classic frame material. A high quality type of steel. Ideal for frames with which you want to achieve an optimal mix of durability, comfort, rigidity and low weight.
Aluminium
Aluminium is one of the most commonly used frame materials for cycles. There are numerous types and qualities of aluminium alloy. Koga uses only the highest quality alloys. At the entry level Koga uses 6061 aluminium. This lets Koga achieve an excellent combination of strength, rigidity and low weight. Koga also uses 7005 aluminium, an alloy with which it’s possible to build frames with very high stiffness and light weight. And for those frames which face the ultimate demand for light weight, robustness and rigidity, Koga uses 6069 aluminium.
Carbon
For everyone who wants to extract the most extreme performance from their bike. A carbon frame consists of carbon fibre layers held together with epoxy resin. A carbon frame is a complex product in which the type of fibres, the fibre orientation, the number of fibre layers, the frame shape and the weave of the fibres all influence the final quality. Koga employs advanced computer analysis (Finite Element Methods) to determine the optimal orientation of the various layers of carbon fibre. The result is super-lightweight frames and perfect rigidity.
Differences between 1k, 3k, 12k and UD carbon fiber
1k
1k is a rare type of fiber used in the cycling industry. It is lighter than other fibers and provides a smoother ride than a larger weave. These smaller carbon fibers also display the incredible amount of craftsmanship needed to complete one of our bikes. The Koga Signature Kimera Carbon 1k is the only model in the Koga collection that features this high-end type of carbon.
3k
3k is the most common carbon fiber that you will find externally on a bicycle. It provides a comfortable ride while still allowing the bike to be stiff and strong enough to handle a powerful rider in the midst of his/her best sprint. This type of carbon fiber is used on the Koga Kimera Road and Koga Signature Kimera Carbon 3k.
12k
12k is the largest weave and the stiffest. This outer layer results in the stiffest "feeling" ride in comparison to 1k and 3k carbon fiber. It is slightly heavier and much less expensive to use in production.
Uni-Directional
Uni-Directional (UD) carbon is another type of carbon fiber that can be used to create a carbon bicycle. UD carbon has fibers that run the same way rather than being woven together. This carbon is used on the Koga Kimera TeamEdition.
