Weighing in at 16.3 oz / 462 g, the Vesper is relatively lightweight for its class, contributing to its appeal among performance-oriented cyclists. The hub also offers customization options in terms of bearing types, catering to different preferences and requirements.

Users have praised the Vesper for its silent operation and high engagement, a significant advantage for those who prefer a quieter ride without compromising on performance. This silent operation is achieved through the unique Sprag clutch system. However, it's essential to ensure proper installation, as the cassette needs to be properly tightened and thread locked to prevent loosening during rides. The hub's quality and fit are highly regarded, and Onyx's customer support and a 10-year warranty add to the product's value.

Despite these positives, some users have reported a 'spongy' feeling during engagement, which might be off-putting for some riders. This sensation is due to the sprag clutch system's operation, which, while providing instant engagement, also has a unique feel compared to traditional ratchet systems. Some users find this sensation smooth and preferable, while others might take time to adjust to it. Additionally, there have been reports of the Vesper hub failing, particularly under heavy loads or with heavier riders, although warranty support seems to be robust.

Onyx Vesper - Silent, Instant Engagement MTB Hubs



Types of Mountain Bike Hubs

Freewheel Hubs

Freewheel hubs are a classic design in which the freewheel mechanism (the component that allows the wheel to spin freely while coasting) is a separate piece that screws onto the hub. This type of hub is commonly found on older or entry-level mountain bikes. Freewheel hubs are known for their simplicity and ease of replacement, as the entire freewheel can be unscrewed and replaced. However, they tend to be less durable under high torque conditions, such as those encountered in mountain biking.

Cassette Hubs

Cassette hubs are now the standard in modern mountain biking. Unlike freewheel hubs, the cassette hub has the freewheel mechanism built into the hub itself, and the gears (cassette) slide onto the hub and are held in place with a lockring. This design allows for a wider range of gears and a more efficient transfer of power from the rider to the wheels. Cassette hubs can handle higher torque loads and are generally more durable and reliable than freewheel hubs, making them a preferred choice for most mountain biking applications.

Direct-Engagement Hubs

Direct-engagement hubs, a relatively newer innovation in mountain biking, are designed for instant power transfer and minimal lag in engagement. These hubs have a mechanism that allows for almost immediate engagement of the drive system when the rider starts pedaling. This results in less lost motion and a more responsive ride, which is particularly beneficial in technical mountain biking where quick bursts of power are needed. Direct-engagement hubs are favored by riders who require precise control and immediate response from their bike.



MTB Hub Materials and Construction

Aluminum

Aluminum is a widely used material for MTB hubs due to its excellent balance of strength, weight, and cost. It is lighter than steel, making it a popular choice for riders looking to reduce the overall weight of their bike. Aluminum hubs are strong enough for most mountain biking demands and come in various designs and colors, offering both performance and aesthetic appeal.

Steel

Steel is known for its exceptional durability and strength, making it a suitable material for MTB hubs in high-stress situations. It's often used in hubs designed for extreme riding conditions or for heavier riders. Steel hubs are typically heavier than aluminum, but their resilience in tough terrains is unmatched. They are a great option for those who prioritize longevity and robustness.

Carbon Fibre

Carbon fibre is a high-end material used in some premium MTB hubs. It's incredibly lightweight and stiff, offering superior performance benefits. Carbon fibre hubs are often chosen by competitive riders and those seeking the best in technology and weight savings. However, they come at a higher cost compared to aluminum and steel hubs. Carbon fibre's rigidity and lightness translate into faster acceleration and a higher degree of responsiveness, making them ideal for performance-oriented riders.



Types of Hub Bearings

Sealed Bearings

sealed mtb bearings

Sealed bearings are the most common type found in modern bike hubs. They are known for their low maintenance and durability. Encased within a sealed unit, these bearings are protected from dirt and moisture, making them less susceptible to wear from external elements. They provide a smooth, consistent performance and are relatively easy to replace when worn out. Ideal for riders who prefer a hassle-free, low-maintenance setup.

Ceramic Bearings

Ceramic bearings represent a step up in terms of performance and efficiency. They are lighter and harder than steel bearings, which reduces friction and increases speed. These bearings are also more resistant to wear and less affected by heat, ensuring a longer lifespan. However, they come at a higher cost. Ceramic bearings are favored by performance-focused cyclists who seek every advantage in efficiency and longevity.

Cup and Cone Bearings

Cup and cone bearings are a traditional design found in many older and some high-end hubs. They consist of loose ball bearings placed between a 'cup' in the hub and a 'cone' in the axle. One of their main advantages is the ability to be serviced and adjusted for smoothness and play. While they require more maintenance and precise adjustment, they offer a level of customizability and repairability that sealed bearings do not. Ideal for enthusiasts who enjoy hands-on maintenance and fine-tuning of their bike components.



Types of Axles

Quick-Release

Quick-release axles are a popular and traditional choice for many bicycles. They consist of a skewer that passes through the hollow axle, clamped in place by a lever-operated cam mechanism. The key advantage of quick-release axles is the convenience they offer; they allow for fast, tool-free removal and installation of wheels, making them ideal for situations where wheel removal is frequent, such as for transportation or tire changes. However, they can be less rigid than thru-axles, which might affect stability, especially in high-performance or off-road situations.

Thru-Axles

mtb thru axle

Thru-axles are increasingly common, especially in mountain bikes and newer road bike designs. They are a single, solid rod that slides through the hub and attaches directly to the bike's frame or fork. This design provides a stiffer and more stable wheel-to-frame connection, enhancing handling and performance, particularly in rough terrain or at high speeds. Thru-axles also improve the alignment of disc brake rotors, reducing the likelihood of brake rub. They require a tool for removal, which can be less convenient than quick-release axles but offers a significant increase in performance and safety.


What to Look For in an MTB Hub?

Hub Engagement Speed

The engagement speed of a hub is crucial, especially in mountain biking. A faster hub engagement results in a quicker response to pedaling. This is particularly beneficial in technical terrains where quick starts and stops are frequent. It enhances the bike's efficiency and performance.

Bearing Quality

Bearings are the heart of a hub's smooth operation. High-quality bearings, like sealed cartridge bearings, offer better durability and protection against elements. They ensure a smoother ride and prolong the hub's lifespan.

Hub Durability

Durability is key in mountain biking. Hubs made from robust materials like aluminum or steel can withstand harsh conditions and impacts. A well-constructed hub not only lasts longer but also maintains performance under various riding conditions.

Bike Compatibility

Compatibility with your bike is essential. This includes making sure the hub fits the frame and fork dimensions, as well as being compatible with your bike's brake system, whether it's a disc or rim brake.

Weight Considerations

The weight of the hub can influence the bike's overall weight and handling. While a lighter hub can be beneficial for agility and speed, it shouldn't compromise the hub's strength and durability. The choice often comes down to personal preference and riding style.

Sound Quality

The sound a hub makes is a personal preference. Some riders prefer a quieter hub, while others enjoy the audible feedback of a louder hub. The sound often correlates with the number of engagement points a hub has.

Brand Reputation and Warranty

Opt for hubs from reputable brands that are known for their quality. A good warranty is also a sign of the manufacturer's confidence in their product, offering peace of mind and assurance of quality.
