A flywheel for a stationary exercise machine having a frictional resistance strap is formed of heat-sensitive plastic, and includes a band of heat-dissipating material disposed about the periphery or rim of the flywheel for frictional contact with the resistance strap. The strap extends around the flywheel rim over the band to provide an adjustable resistance to the flywheel's rotation. The band dissipates the frictionally generated heat arising from movement of the flywheel within the strap.
