Transform any road bike into an indoor cycling machine with a progressive fluid resistance system that ramps up as you pedal faster, simulating everything from an easy warm-up to a steep climb without manual adjustment. A heavy-duty aluminum alloy shaft and low-noise resistance unit keep friction and vibration low for quiet rides at any hour. The stand fits wheels from 26 to 29 inches or 700C, so most road bikes drop in without extra gear. Folding down to a compact footprint, it stores easily in a closet or trunk, while the quick-release skewer makes setup a matter of minutes. A carbon steel frame forms a stable triangular base, and the included front wheel riser block plus non-slip foot pads support up to 330 lbs for shake-free training.
