Elevate your ride with a drivetrain component that reflects your ambition and demands. This high-performance cassette freewheel is engineered for cyclists who value weight-savings, precision and reliability on every terrain. Crafted from carbon-steel and built with the HG (Hyperglide) spline standard, it delivers seamless shifting across 9, 10, 11, 12 or 13-speed configurations. Upgrade your bike’s gearing and experience smoother transitions, stronger engagement and the freedom to climb harder and ride smarter.

Key Features

  • Carbon-steel construction delivers durability and strength under load, without sacrificing performance.

  • Includes options across 9/10/11/12/13-speed setups, making it compatible with a wide variety of drivetrains and upgrades.

  • HG spline design ensures compatibility with most Shimano-style freehubs and optimized shift ramping. Wikipedia+2Wikipedia+2

  • Ultralight orientation reduces rotating mass — enhancing acceleration feel and responsiveness.

  • Suitable for mountain bikes, road bikes and hybrid setups—ideal for riders upgrading their drivetrain or building a high-spec bike.

Why Choose Our SUNSHINE Ultralight HG Carbon-Steel Cassette
While many aftermarket cassettes compromise either material quality or shifting precision, this model strikes the optimum balance: a robust carbon-steel build (better wear resistance) combined with HG spline compatibility and ultralight design. Feedback from cycling communities suggests the brand performs well for the money:

“I have that cassette on my 3000 w e-bike … it’s doing well. … All the gears are steel so, cheap, heavy and strong.” Reddit
For riders who want cost-effective performance upgrades rather than premium-price ornaments, this cassette is a smart choice.

Perfect For (Occasions & Uses)

  • Cyclists building a lightweight machine and seeking to shave rotating mass with drivetrain upgrades.

  • Mountain bike riders needing a reliable 12 or 13-speed cassette for wide-range gearing and smoother climbs.

  • Road cyclists upgrading to higher-speed setups (11/12/13) with compatible HG freehub bodies.

  • DIY bike mechanics or home-wrenchers looking for a value upgrade component without compromising core performance.

How to Use & Care
Install on compatible freehub body: ensure the HG spline is clean, apply light lubrication on the freehub splines, slide the cassette into place aligning the wide spline, and torque the lockring to manufacturer spec. Regularly clean the cassette by removing the wheel, degreasing the cogs, and re-lubricating the chain to maximize gear life and smooth shifting. Manuals++1

Ride Faster. Shift Better. Upgrade Now.
Step into a smoother, stronger drivetrain experience with the SUNSHINE Ultralight HG Carbon-Steel Cassette. Because your ride deserves nothing less.

    Beautiful dress
    Really happy with this purchase. I only wish I had steamed it before trying it on because it arrived with a few wrinkles from shipping.

    Worth every dollar
    The quality surprised me. The material has a nice weight and doesn't feel see-through at all. I'll definitely order another style.

    Runs slightly roomy
    I was between sizes and ordered the larger one. It still looked great, but I probably could have gone with my usual size.
