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
