JetBlack Z1-Pro Fluid Indoor Trainer (with SQR Fit System)

The JetBlack Z1 Pro Fluid is an indoor bicycle trainer known for its high-quality fluid resistance, offering a more realistic road-like experience compared to magnetic trainers. It features one of the heaviest flywheels available, providing an extended run-down time. The unique fluid technology increases resistance exponentially with speed, making workouts more challenging as you pedal faster. The JetBlack HydroGel Roller significantly reduces noise by 55% and decreases tire wear by 25-30%. Its 3-dimensional polyionic polymer structure gives it a jelly-like feel, minimizing tire wear by reducing contact heat and slippage compared to traditional alloy rollers.
