Q. Are twenty nine inch wheels safer then their twenty six inch counter parts?

A. 29 inch wheels offer greater control by athletes when racing under stress. The 29 inch wheel has a lower angle of attack to obstacles such as rocks and roots. Bikes are less likely to be forced off the trail and riders are less likely to flip off their bikes causing personal injury. 29 inch wheel bikes also feature lower bottom brackets in relation to the center of the axle of the wheels. The lower ‘drop’ results in a lower center of gravity, giving riders more control when racing.
