Types of shimano nexus 5-speed hubs

When it comes to Shimano Nexus 5 speed hub, there are a few varieties to take note of whether one is looking for a reliable internal gear hub for a bicycle. The Nexus series by Shimano is designed primarily for city bikes, comfort bikes, and touring bikes. While geared hubs are less common than derailleur systems in road bikes, they do offer the benefit of shifting gears even when the bike is stationary, as opposed to derailleur systems where the rider has to be pedaling to shift.

The Shimano Nexus 5-speed hub bike comes with some merits, like the fact that it is low-maintenance, offers smooth gear changes, and has a good range of gears. Also, because the gears are internal, they are less likely to be damaged than external systems, giving the bike a longer lifespan.

The variations of the Nexus 5-speed hub include:

• Nexus Inter 5 (without rollerbrake): This version is the one that does not have roller brakes and thus can be used with a wider range of wheel sizes, including non-standard sizes. It comprises a gear mechanism that is fully sealed within the hub, providing more reliability and offering smoother gear changes.
• Nexus 5 (with rollerbrake): This hub has a built-in roller brake that provides a stopping mechanism for bikes that do not require traditional rim brakes. Roller brakes are low-maintenance and offer consistent braking power. The rollerbrake version of the Nexus 5 speed hub is suitable for bikes with a fixed brake mount or those who prefer the simplicity of hub-mounted brakes.
• Nexus 5-speed hub with dynamo: This type of 5-speed hub is used on bicycles equipped with wheel hubs that can generate electricity using a dynamo. The dynamo uses the rotational energy from the bike wheels to power bicycle lights or other electronic gadgets. This version of the Nexus hub conveniently integrates gear systems and the dynamo for lighting, reducing clutter and the need for additional batteries or charging.

Within these broad categories, there may be sub-categories based on features such as color, weight, or the type of roller brake, but these are the main variations.
