Bike Cassettes & Freewheels

Bike Cassettes & Freewheels are the core of your gearing performance — controlling cadence, power, and climbing ability. Whether you ride a road bike cassette 10-speed or a mountain bike 11-speed cassette, a quality drivetrain ensures smooth shifting and maximum efficiency.

At The Outdoor Warehouse, we offer a wide selection of Shimano, SRAM, and SunRace cassettes for every type of bike — from wide-range MTB cassettes to lightweight road bike options. Perfect for upgrades, replacements, or full drivetrain rebuilds.

Pro Tip

When upgrading your bike cassette, always pair it with a new bike chain to prevent skipping and premature wear. Match your freehub body and derailleur capacity for best compatibility. Clean your cassette regularly to remove debris and extend its lifespan.

Frequently Asked Questions

What’s the difference between a cassette and a freewheel?

A cassette slides onto a freehub body, while a freewheel has a built-in ratchet mechanism. Most modern bikes use cassettes for better performance and easier maintenance.

Can I upgrade to a 12-speed cassette?

Yes, if your hub, derailleur, and shifter are compatible. Many 10 or 11-speed drivetrains can be upgraded by replacing the cassette, chain, and shifter together.

How often should I replace my bike cassette?

Replace every 3,000–5,000 miles or when shifting feels rough or skipping occurs. Use a chain checker tool — if chain wear exceeds 0.75%, it’s time to replace the cassette too.

What cassette size is best for climbing?

Choose a wider-range cassette such as 11–34T or 11–40T for steep terrain. A larger lowest cog (higher “T” number) makes climbing easier by reducing gear ratio strain.
