Ultra smooth, Ultra quiet, and Ultra-realistic. The TrakStand Ultra cycle trainer features a patented CENTRIFORCE resistance unit. Up to 745 watts of resistance is generated by bearings in a centrifugal clutch which move outward and push the flywheel onto a resistance plate with acceleration.

Provides an amazingly smooth, quiet, and progressive resistance that feels just like a hard road ride. 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.

Super-stiff folding aluminium frame with height adjustable legs, which allows the rear wheel to be as close as 12 mm to the ground. Fits 700C, 650C and 26 inch wheel bikes.

3 different resistance levels available by swapping the internals around. Blackburn no-quibble lifetime warranty.
