Bring vibrant colour and elite performance to your mountain bike with the VORTEX Rainbow MTB Cassette. This precision-engineered flywheel is designed to provide exceptionally smooth shifting and a standout aesthetic for serious cyclists. Crafted from premium chrome molybdenum steel, it delivers the strength and wear resistance required for demanding mountain and road terrains.
Durability is at the core of the VORTEX Rainbow MTB Cassette, which utilizes high-tensile chrome molybdenum steel to ensure long-lasting performance. This material choice guarantees that the cassette can handle high-torque climbs and rapid descents without compromising its structural integrity. Each unit undergoes high-precision machining to ensure optimal chain engagement and consistent pedalling efficiency.
The eye-catching rainbow finish of the VORTEX Rainbow MTB Cassette adds a premium, customised look to any drivetrain. Available in multiple speeds—including 8, 9, 10, and 11-speed options—this cassette allows riders to upgrade both their bike's aesthetics and its mechanical response in one bold move. The "dazzling colour" classification ensures your bike stands out on every trail.
Whether you are tackling steep inclines or accelerating on flat sections, the VORTEX Rainbow MTB Cassette offers a versatile gear range. With options such as 11-36T and 11-42T, riders can maintain the perfect cadence across various landscapes. The 8S 11-42T model specifically weighs approximately 431g, providing a robust yet balanced addition to your rear hub assembly.
The VORTEX Rainbow MTB Cassette is designed for broad compatibility with most standard mountain bike drivetrains. The high-precision machining guarantees that gear changes remain crisp and reliable, reducing the risk of chain slippage under load. Each package also offers an optional lock cover colour, allowing for even further personalisation of your gear system.
Ideal for riders looking to replace worn-out components or upgrade their gear ratio, this cassette flywheel is a professional-grade choice. The packing list includes one high-quality chromium molybdenum steel cassette flywheel, ready for immediate installation. It is the perfect blend of high-end style and rugged engineering for the modern cyclist.

Choosing the right drivetrain component is essential for maintaining your bike's efficiency. A VORTEX Rainbow MTB Cassette made from chrome molybdenum steel is a superior choice for riders who prioritise durability over the extreme weight savings of aluminium. Steel cogs provide a much longer lifespan and are more resistant to "shark-finning" (the wearing down of teeth) caused by high-tension gear shifts. When selecting your cassette, ensure the speed count (e.g., 11-speed) matches your existing derailleur and shifter to avoid mechanical interference and poor shifting quality.
The gear range, such as 11-42T, determines your bike's climbing ability. A 42T large sprocket is ideal for steep mountain trails, providing a "granny gear" that makes climbing significantly easier. However, check your rear derailleur's "capacity" to ensure it can handle a 42T cog; some short-cage derailleurs may require a hanger extension to clear the largest sprocket. The 11T small cog ensures you still have plenty of top-end speed for descents and flat roads.
Aesthetics play a huge role in modern custom builds. The "dazzling colour" rainbow finish is achieved through a specialized coating process that doesn't just look good but also provides a layer of surface protection against moisture and grit. This finish is perfect for riders who want a "boutique" look without the boutique price tag. Pairing this cassette with a matching rainbow chain can create a stunning, integrated look for your drivetrain.
Installation of a cassette requires a specific lockring tool and a chain whip. When fitting your new VORTEX Rainbow MTB Cassette, ensure that the splines on your freehub body are clean and lightly greased. Properly torquing the lockring (usually to 40Nm) is vital to prevent the cogs from wobbling, which can lead to ghost shifting or damage to the freehub body itself. Always check your chain wear when installing a new cassette; a stretched chain will quickly ruin the new teeth of your rainbow flywheel.
Performance consistency is what separates professional gear from entry-level parts. The high-precision machining on VORTEX cassettes includes shifting ramps and specially profiled teeth that help the chain move smoothly between gears under load. This reduces the "clunk" often felt during gear changes and ensures that your power transfer remains efficient. Whether you are a weekend warrior or a daily commuter, these technical details ensure a more reliable and enjoyable riding experience.
Finally, consider the weight-to-durability ratio. At approximately 431g for the 8-speed 11-42T model, it is a sturdy component that can handle the rigours of off-road cycling. While lighter cassettes exist, they often wear out much faster and cost significantly more. For the majority of riders, the chromium molybdenum steel construction of this rainbow flywheel offers the best balance of performance, style, and value.
Does the rainbow finish wear off over time?
While the coating is durable, natural friction from the chain will eventually show some wear on the contact points of the teeth.
Is this VORTEX Rainbow MTB Cassette compatible with road bikes?
Yes, it can be used on road bikes as long as the freehub body and derailleur capacity are compatible with the chosen speed and gear range.
Do I need a new chain when I buy this cassette?
It is highly recommended to install a new chain with a new cassette to prevent premature wear and ensure smooth shifting.
What is the weight of the 8-speed 11-42T version?
This specific model weighs approximately 431g.
Can I choose the colour of the lockring?
Yes, the colour of the lock cover is optional to further customise your setup.
What material is the cassette made from?
It is manufactured from high-strength chromium molybdenum steel for maximum durability.
Does it fit standard HG (Hyperglide) freehub bodies?
Yes, the high-precision machining ensures compatibility with most standard MTB drivetrain hubs.
Which gear range is best for climbing?
The 11-42T range is excellent for climbing, as the 42T cog provides significant mechanical advantage on steep hills.
