 A notable boost to their popularity came with Lance Armstrong, racing and winning on a Gary Fisher 29er.Advantages to the larger wheel formats are less need for suspension due to a decreased angle of attack, and also less loss of momentum.Disadvantages include increased weight, decreased acceleration, higher rolling inertia, rider fit issues for those under 5'5" (165 cm), and slower handling, although handling issues are being addressed successfully in newer designs with geometry changes like steeper head tube angles and higher fork offsets.
