Get stronger and have fun riding indoors with Giant's Cyclotron Fluid ST Trainer. Using a 7.5-pound flywheel and Real Road Simulation technology, it provides up to 2000 watts of quiet, smooth, progressive resistance. Well thought out details abound like the TurboTron 70mm-diameter roller with internal cooling fins that reduce heat build-up and prolong your tire life. The quick-release mount and torque-set knob make bike installation and removal a snap as well. Go ahead, jump out of the saddle and work it, the steel frame provides excellent stability, while the anti-skid feet keep your trainer in place and your floors clean.
