help Saris Fluid2 FAQ
Is the Saris Fluid2 a fully smart indoor bike trainer?
The standard Fluid2 is a wheel-on fluid trainer, not a fully controllable smart trainer. The Smart Equipped version adds a speed or cadence sensor for Bluetooth and ANT+ app connections, but it does not electronically change resistance like a direct-drive smart trainer.

Which cycling apps work with the Saris Fluid2 Smart Equipped setup?
Saris lists apps such as Zwift, Rouvy, TrainerRoad, and Kinomap as compatible with supported sensors and connections. These apps can use wheel speed and the trainer's known resistance curve to estimate training data.
What bike wheels and axles fit the Saris Fluid2?
The trainer supports common 650b and 700c wheels, plus 27.5-inch tires up to 2.0 inches wide and 29-inch tires up to 1.5 inches wide. Its standard rear-dropout settings are 120, 130, and 135 mm, while some thru-axle bikes need a separate adapter.
Does the Saris Fluid2 measure real power?
The trainer itself uses progressive fluid resistance rather than a built-in power meter. The Smart Equipped package supplies a speed or cadence sensor, and Saris lists power feedback for that setup at about plus or minus 5 percent.
