Is it really worth the time and effort to build your own wheels, or are the benefits of custom-built wheels largely a myth perpetuated by enthusiasts who enjoy tinkering with their bikes? Ive seen many riders swear by the improved performance and reliability of hand-built wheels, but others claim that the differences are negligible and that the time spent building wheels could be better spent training or fine-tuning other aspects of the bike. What are the actual advantages of building your own wheels, and are they significant enough to justify the investment of time and money? Are there any specific scenarios or types of riding where custom-built wheels truly make a difference, or is it mostly a matter of personal preference?
