The material question: carbon or aluminium?
As far as choosing a frame is concerned, it’s a fundamental question for many. As is often the case, however, both materials have their advantages and disadvantages. The significant advantage of carbon over aluminium is its low weight combined with high stiffness values. Carbon fibres, which are imbued with a high degree of vibration damping, provide more comfort and allow for specifically flexible constructions. Carbon also has the advantage of a much freer design, which can be seen in designs such as flatter tops on aero handlebars. However, compared to aluminium, carbon road bike handlebars are more expensive and are also more delicate. However, since most of the handlebar surface is wrapped with tape, this aspect, unlike the frame, plays a rather minor role. Even so, you should still pay attention to the correct tightening torques for carbon handlebars and use a torque wrench and carbon assembly paste for assembly. Aluminium has its own advantages as well, and not just in terms of price. In this regard, manufacturer LEVELNINE offers very good and inexpensive road models. Furthermore, aluminium is robust and can also be forgiving when it comes to improperly tightened screws. Even if aluminium handlebars weigh a little more overall than their carbon counterparts, the difference is only perceptible by a few hundred grams at most. Incidentally, be on the lookout for those who use aluminium handlebars in their "Pain Cave" during training. That said, sweat is a known cause of unpleasant corrosion disasters that can build up under handlebar tape. Carbon has a clear advantage here.
