The classic Spinner® model, the Spinner® Shift is built to be the workhorse of your facility. It features a heavier steel frame and more adjustment options, like the fore/aft handlebar adjustments, than the Spinner® Ride. The Spinner® Shift is a great choice for facilities with 10 or more classes per week, and seeking differentiation in their well established indoor cycle offering. Available with both chain and belt drive. Superior feel from our perimeter weighted flywheel Every Spinner® model uses a 43 lb. (19.5 kg) perimeter weighted flywheel. Putting more weight on the outer ring of the flywheel creates more inertia, helping to give each Spinner® that signature feel of smooth, fluid motion more closely matching outdoor cycling than any other bike. Experience driven design for reliability With aerodynamic styling and rounded tube shapes, all Spinner® bikes are designed to shed sweat and be easier to clean and maintain. All aluminium adjustment extrusions and covered rear stabilisers
