Easy to install, quiet, and smooth pedaling. My first experience with a trainer of this type was very positive.

Good virtual workouts

Pedro Ivo

Excellent roller and good performance simulator in general, the only thing to be regretted is the terrible squeaking noise that started making just after 6 months, it's really annoying, but it's still a good simulator.
