You’ll want to double-check what speed bike you have, but no matter what, if you’re putting it on a direct drive — NOT a wheel-on trainer — you’re going to need a cassette. Sure, you could use the cassette on your wheel, but that requires additional tools and labor every time you want to switch up. And why do that when you could be pedaling?

Available in a 10- or 11-speed gear ratio, the MicroShift Trainer Cassette is compatible with all direct drive smart trainers with a SRAM or Shimano free hub body.

• Continuously molded cogs for a more consistent shifting performance.
• Compatible with SRAM and Shimano systems
• Aluminum lock ring.
• Cassette Speeds: 11-25T
