Typical materials that make up pedal bodies are aluminium, carbon, composite plastic materials and titanium. Aluminium offers a good monetary value and very good durability – especially for mountain biking, where you can run into a fair share of rocks and hard objects. If you want to save weight and are prepared to invest a little more, you can opt for carbon pedals for your road bike. In mountain biking, on the other hand, carbon pedals are more of an exception that is usually found in cross-country sports. Titanium is another option for building lightweight yet robust pedals, but it is also rather seldomly used. Technical composite materials, often fibre-reinforced, are found in both road bike and mountain bike pedals, and also offer a very good price-performance ratio. Steel is, of course, a proven suitable material for axles. Using titanium, however, will help you to spare a few grams around this area.
