The Kimera is one of the last production bikes with a triple drivetrain. In the age of eleven-speed cassettes, these are threatened with extinction, which is why Koga has largely equipped the bike with the "old" ten-speed 105. Only the brakes are from the new 105, and those who opt for a triple usually have good reasons for doing so and accept the inevitable extra weight. One argument remains the possibility of combining a wide range of gear ratios with a narrow gradation. However, if you utilise the possibilities of modern eleven-speed drivetrains, you can achieve almost the same range of gear ratios. A comparison between the older and the new 105 fitted here shows that the new shifting system is more precise and the slimmer grips are more comfortable to hold. Positive: The extremely sporty frame is available up to size 66.
