The Saris Fluid2 Smart Equipped is ready for any "virtual" or "non-virtual" training ride. It's the ideal setup for athletes looking to join fun, virtual communities, like Rouvy and Zwift, without a traditional smart trainer. Simply install the magnetless speed sensor on the rear wheel of your bike, mount your bike to the solid Fluid2 trainer with the innovative clutch knob, connect to your indoor cycling app of choice via Bluetooth or ANT+ (USB sold separately).
