SUNSHINE Road Bike Cassette Review: 8 to 12 Speed HG Cogset
Problem & Solution
A worn or mismatched rear cassette leads to imprecise shifting, skipping chains under heavy pedaling load, and inefficient power transmission. For cyclists looking to replace a worn-out cogset or adjust their gear ratios for steeper climbing or faster flat riding, finding a compatible replacement can be confusing given the variety of speed standards and hub interfaces.
The SUNSHINE Road Bike Cassette addresses this challenge by providing a direct replacement option across a broad spectrum of speeds (8, 9, 10, 11, and 12-speed) designed specifically for the widely used Shimano Hyperglide (HG) freehub standard. It offers multiple max-tooth cog sizes (from close-ratio 23T options up to wide-range 36T cogs) so riders can tailor their cadence and gearing directly to their riding style.
Who Is It For?
This product is designed for road cyclists, bike commuters, and home bicycle mechanics looking to service or upgrade their drivetrain. It is ideal for riders who use standard Shimano HG spline freehub bodies and need a replacement cassette in 8V, 9V, 10V, 11V, or 12V configurations.
It is particularly useful for riders adjusting their gear ratio—whether seeking a tight road ratio for smooth flatland pedaling (e.g., 23T or 25T max) or wider gearing for tackling steep climbs (e.g., 32T, 34T, or 36T max).
Key Features

- Standard HG spline compatibility ensures straightforward fitment on conventional freehub bodies
- Offers low-gear options up to 36T for improved climbing capability on road and gravel routes
Cons
- Larger max cog sizes (32T, 34T, 36T) may require a long-cage rear derailleur or a derailleur hanger extension
- Exact alloy or steel material composition for individual cogs is not specified in available data
FAQ
The cassette utilizes the standard Shimano HG spline pattern. It works with standard HG-compatible freehubs and shifting systems operating on matching speed counts (e.g., an 11-speed cassette requires an 11-speed shifter and chain).
Short-cage road derailleurs typically max out around 28T or 30T. Using a 34T or 36T cassette will likely require a medium/long-cage derailleur or an added derailleur hanger extension (Road Link) to clear the largest sprocket.
No, this model is designed specifically for standard Shimano HG (Hyperglide) spline freehubs. It is not compatible with SRAM XD/XDR or Shimano Micro Spline freehubs.
Yes, installing a new cassette with an old, stretched chain can lead to accelerated cog wear and skipping gear transitions. Replacing the chain alongside the cassette is standard recommended practice.
Final Verdict
A practical choice for cyclists needing a direct replacement cassette on a standard HG freehub body. Highly versatile due to the wide selection of speed options (8-12 speed) and cog sizes (23T to 36T). However, riders choosing larger cog sizes must verify their rear derailleur cage length and chain length prior to installation.
