The latest generation of carbon road bikes under £2000 offer a fantastic combination of performance and value. It's a very good material for bike frames, both light and stiff, two very desirable features in a bike frame. Modern carbon frames are comfortable as well. Gone are the days when you would expect a harsh ride from a carbon bike.
Entry-level carbon road bikes normally offer slightly less exotic groupsets and components. Yet tend to feature very well-engineered frames. Look for a carbon frame instead of steel as it’ll be almost as strong but just a fraction of the weight.
