The Drive Belt is a necessary component of any kPulley device. Since it’s a consumable part it’s recommended that you have a spare Drive Belt nearby in order to keep your flywheel training going at all times.
The Drive Belt and its attachment to the axle is the most sensitive part of the kPulley. Be attentive to wear and check regularly. When the Belt shows signs of wear and tear, trim the end by cutting off the damaged area or replace it with an original spare Drive Belt.
