Saris Fluid2 Trainer Smart Equipped Black, One Size

Saris takes its top-selling trainer in the USA and adds a dual-band ANT+ and Bluetooth speed sensor so you can reap the benefits of virtual training via apps like Zwift and Rouvy. The fluid resistance unit is quiet (64-68 decibels at 20mph), and offers a progressive power curve that increases the resistance as you shift gears and pedal harder-just like if you were on the road.
