Your parts checklist
Cassette
Not needed — this trainer uses your existing wheel and cassette (or virtual shifting).
Freehub body
Uses your bike’s own wheel — no freehub body to buy.
Thru-axle adapter
Not required for this trainer’s setup.
Mounting your bike
What the Tacx Flow Smart actually asks of you, in order — resolved from its own spec, not a generic manual.
- Leave the rear wheel on and clamp the frame at the axle, then set the roller against the tyre. A dedicated trainer tyre cuts noise, slip and wear.
- Spin the cranks by hand before you clip in: the chain should run quiet and straight. Noise here almost always means chainline or cassette spacing, not a faulty trainer.

Frequently asked questions
It depends on the trainer: typically a cassette matching your bike’s speed on the right freehub body, and a thru-axle adapter if your frame is thru-axle. The checklist above resolves exactly which of these the Tacx Flow Smart needs.
