Description
The Shimano Altus HG31 8-Speed Cassette is a dependable entry-level MTB cassette built for riders who need consistent, low-maintenance shifting on everything from Pune's weekend trail rides to daily commutes through Chennai or Kolkata. At Rs. 880 with free delivery above Rs. 2,500, it offers genuine Shimano engineering at a price that makes upgrading or carrying a spare cassette easy to justify.
Use Cases
Climbing setups. Wide-range cassettes for steep Western Ghats, Lavasa, and Nilgiris climbs.
Flat-terrain training. Tight-ratio cassettes for criterium and flat-road training in cities like Chennai and Ahmedabad.
All-rounder. Mid-range cassettes for rides combining flats and climbs.
Our Take
For Indian mountain bikers and hybrid commuters running an 8-speed drivetrain, the Altus HG31 punches well above its price. Shimano's HG spline pattern ensures predictable indexing even after the kind of monsoon mud-bath you encounter on Lonavala trails or Coorg forest roads. The steel construction resists the accelerated corrosion that humidity and dust bring to cheaper cassettes, keeping your shifting crisp across thousands of kilometres.
Sizing for Indian Riders
This cassette is sized by speed count and sprocket range, not by body dimensions. Confirm your rear derailleur is an 8-speed unit and that your freehub accepts an HG-compatible cassette — the overwhelming majority of entry and mid-range MTB hubs in India do. If you ride steep Western Ghats climbs or Ooty switchbacks, check that your derailleur's capacity covers the full cassette range before ordering.
Compatibility Notes
Designed for 8-speed HG-compatible freehubs. Pair with an 8-speed Shimano or compatible chain; do not mix with 9, 10, or 11-speed chains. Works with Shimano 8-speed shifters and compatible third-party units. Replace the chain at 0.5–0.75% wear using a chain wear tool to avoid premature cassette wear. Clean and re-lube weekly during monsoon season.
Pairs Well With
Complete your drivetrain service kit with a wet-condition chain lubricant suited to Indian monsoon riding, a chain wear checker tool, an 8-speed replacement chain, and a cassette lockring removal tool for home servicing. All categories are available at Cobbled Climbs.

Frequently Asked Questions
What is the Shimano Altus HG31 8-Speed Cassette best used for?
The Altus HG31 is best suited to mountain biking and hybrid commuting on 8-speed drivetrains. It handles trail riding, weekend climbs in the Western Ghats or Coorg, and daily urban commutes equally well. Its steel construction copes with the dust and humidity typical of Indian riding conditions, making it a practical choice for riders who prioritise reliability over weight savings.
What size Shimano Altus HG31 cassette should I order?
Cassette sizing here means confirming speed count and freehub compatibility, not a physical size. This is an 8-speed HG cassette. Verify your rear derailleur, chain, and shifters are all 8-speed rated. Most entry and mid-range MTB wheels sold in India use an HG-compatible freehub, so fitment is rarely an issue. Check your derailleur's sprocket capacity if you ride steep climbs.
Will the Shimano Altus HG31 hold up in monsoon conditions and 35°C+ heat?
Yes. Steel sprockets resist the accelerated corrosion that affects cheaper cassettes during India's monsoon months. To maximise lifespan, clean and re-lube your chain weekly during the rains using a wet-condition lubricant, and switch to a dry or wax lube post-monsoon. A full drivetrain clean before and after monsoon season will keep the cassette shifting crisply for longer.
How does the Shimano Altus HG31 compare to higher-speed Shimano cassettes?
The Altus HG31 offers fewer gear steps than 9, 10, or 11-speed cassettes, meaning slightly larger jumps between sprockets. For trail and commute riding this is rarely noticeable, but competitive riders or those tackling steep Ooty or Leh gradients may prefer a wider-range, higher-speed option. The trade-off is significantly lower cost and greater compatibility with budget 8-speed groupsets common in India.
Is the Shimano Altus HG31 worth Rs. 880 in India, and what warranty does it carry?
At Rs. 880 with free delivery above Rs. 2,500 and cash on delivery available, the Altus HG31 represents strong value for 8-speed MTB and hybrid riders. Shimano backs its components with a standard manufacturer's warranty against defects; contact Cobbled Climbs with your order details for warranty support. Replacing a worn cassette promptly also protects your chain and chainring from premature wear, saving money long-term.
