Kinetic Riser Ring

Manufacturer Warranty: lifetime
Put the Kinetic Riser Ring under your front wheel and watch the pros ride last year's tour while you sit and spin for a few hours. The Riser Ring accommodates tires up to 2. 25 inches wide and features four heights in half-inch increments to level out your bike. If you really want to enhance the simulation, stack some phone books underneath and pretend you're climbing Ventoux.
