When aftermarket is the better choice
An aftermarket part is not automatically worse or better than the original. It is another engineer answering the same question.
- Durability: race parts are often made from tougher material than the series item.
- Weight: aluminium and titanium solutions cut mass.
- Cost: for wear items aftermarket is often the better value.
Check model and year compatibility before buying. Replace wear parts such as sprockets and chain as a set so they wear evenly.
