Is the conventional wisdom that mountain bikes with narrow-range cassettes are completely unsuitable for long-distance riding based on outdated assumptions, and are we being overly cautious by immediately dismissing them as a viable option for endurance rides?
It seems that many people instinctively reach for the widest-range cassette they can find when building a bike for long-distance riding, but is this really necessary? Are there situations where a narrower-range cassette might actually be beneficial, such as when riding on relatively flat terrain with a strong tailwind, or when the rider is particularly fit and able to maintain a high pace?
Some might argue that the additional weight and complexity of a wide-range cassette is actually a hindrance, and that a narrower-range cassette would allow for a more streamlined and efficient drivetrain. Others might point out that the trend towards 1x drivetrains in mountain biking has shown that a narrower range of gears can be perfectly adequate for a wide range of terrain and riding styles.
Of course, there are also arguments to be made that a narrower-range cassette would leave riders vulnerable to unexpected changes in terrain or weather, or that it would be inadequate for riders who are less experienced or less physically able. But are these concerns based on real-world experience, or are they simply a matter of conventional wisdom?
Its also worth considering the fact that many professional cyclists have been using narrow-range cassettes for years, and have developed strategies for dealing with the limitations of these cassettes. Are amateur riders being overly cautious by assuming that they need a wider range of gears in order to tackle long-distance rides?
Ultimately, the question is whether a mountain bike with a narrow-range cassette can be a viable option for long-distance riding, and whether the conventional wisdom on this topic is based on fact or fiction. Can anyone provide some insight into this, and share their experiences with using narrow-range cassettes for long-distance riding?
