Direct-drive and wheel-on differ in noise, not just in price · review
A wheel-on fluid trainer with progressive resistance, a stated 69 decibels at 20 mph, and a speed sensor that connects it to Zwift and Rouvy.
Our conclusion The dependable non-smart trainer: quiet, simple and honest about its noise figure.
A fluid trainer gives you road-like resistance with nothing to pair and nothing to update. The Saris Fluid2 adds one small thing: a speed sensor, so apps can follow your ride.
Fluid resistance with a progressive feel, a stated 69 decibels at 20 mph, a speed sensor for Rouvy, Zwift and other apps, and one month of Rouvy. A quick release skewer is included, and a thru-axle bike needs an adapter sold separately.
The faster the rear wheel turns, the harder the fluid pushes back. You change effort with your gears, as you would outdoors. No app can raise the resistance on a climb. If you want that, the Wahoo KICKR CORE 2 on this shelf is the direct-drive answer, at about three times the price.
Check your rear axle, because that decides the adapter. Plan on a trainer tire or an old rear tire, since a wheel-on roller wears rubber quickly. Put a mat underneath, and know that a floor transmits more noise than the headline decibel figure suggests.

No. The sensor reports your speed, so the app can estimate your effort, but this trainer has no motor to change resistance. You change gears instead.
It comes with a quick release skewer. Saris says a thru-axle bike needs a separate adapter.
