The new TrakStand Ultra features our patented CENTRIFORCE resistance unit with a centrifugal clutch for amazingly smooth, silent and progressive resistance that feels just like a hard road ride. And unlike magnetic and fluid trainers which lose speed quickly, CENTRIFORCE has a smooth rollout when coasting, so your pedal stroke feels more natural in the dead spots or when you ease up on the pedals. The Ultra also features adjustable height, which allows the rear wheel to be as close as 1/2" to the ground. No more phone book under the front wheel.
