If it's important to you to make every workout count, the Fluid2 trainer is the most valuable weapon you can add to your indoor training arsenal.
Saris engineers designed the Fluid 2 to capture real road feel through the use of a 2.75 lb individually precision–balanced flywheel for more momentum and stability of your rear wheel.
They've also adjusted silicone fluid levels for better resistance and improved the position of sealed–cartridge bearings for better inertia and an ultra quiet ride that ensures increased wattage as you increase your speed.
And just like riding outside, simply shift gears to increase or decrease resistance. When you spin your wheels on the Fluid2 it feels like you're actually getting somewhere.
