The Shimano CS-HG41-8 Acera cassette represents a robust and affordable 8-speed drivetrain solution for MTB, trekking and urban use. Featuring Shimano's Hyperglide technology, it ensures precise and smooth gear changes even under load, thanks to engineered tooth profiles and strategically positioned shift ramps. With its 11-32T range, this cassette offers an excellent compromise between responsiveness on flat terrain and climbing capability on sustained ascents.

Technical highlights

• Hyperglide technology: Optimized ramps and tooth profiles for fast, clean and seamless gear changes, even under full effort. The chain is continuously guided to the next sprocket, eliminating hesitation.
• Lightweight construction: Cut-away sprockets reducing weight without compromising rigidity or durability. Compared to previous generations, the CS-HG41-8 displays an attractive weight for its range level (approximately 308-330 g depending on sources).
• Anti-corrosion finish: Silver nickel plating on all sprockets and anti-corrosion treated steel lockring. Increased resistance to wear and corrosion, ensuring longevity.
• Wide compatibility: Compatible with HG and IG 8-speed chains (CN-HG40, CN-HG71, etc.) and standard Shimano 8-speed freehub bodies. Integrates perfectly into Acera, Altus and other 8-speed groupsets.

Range and usage

The 11-32T range (11-13-15-18-21-24-28-32 teeth) offers versatile gearing: the small sprockets (11-15T) ensure speed on road and flat terrain, while the 32-tooth sprocket allows you to tackle steep slopes with ease. Ideal for recreational MTB rides, cycle touring and hilly urban commutes. This cassette is aimed at cyclists seeking reliability, ease of maintenance and accessible performance.

Available variants
