Shopping for a new direct drive smart trainer? Some need a cassette. Zwift makes it easy to get started with both a 10- and 11-speed option.

You’ll want to double-check how many speeds your bike has. Sure, you could use the cassette from your wheel, but that requires additional tools and labor every time you want to head outdoors.

• Continuously molded cogs for a more consistent shifting performance.
• Compatible with SRAM and Shimano systems.
• Aluminum lock ring.
