Blackburn Trackstand Ultra Bike Trainer

Ultra-smooth, ultra-quiet, ultra-realistic resistance—Trackstand Ultra features the patented CENTRIFORCE™ resistance unit. CENTRIFORCE uses a centrifugal clutch for amazingly smooth, silent and progressive resistance that feels just like a hard road ride. CENTRIFORCE has a smooth rollout when coasting; pedal strokes feel more natural in the dead spots and when you ease up on the pedals. Features adjustable height, which allows the rear wheel to be as close as a half inch to the ground—no more phone book under the front wheel! Three different resistance curves ensure a custom feel and are user-serviceable with minor disassembly. Replaceable friction resistance element. Folding aluminum frame.
