The Parts Kit for Heavy Duty Training Wheels includes the original hardware package that would normally be included with a set of BikeHard Heavy Duty training wheels. 2 Extension bolts (“standoffs” – part A), 2 Wheel fixing bolts (part C), 2 Wheel Fixing Nuts (part E), 2 Height Adjustment Bolts (part G), and 2 Height Adjustment Nuts (part H). Hopefully, no parts are ever lost from a training wheel set, but if they are, these are the parts that replace them.
Features

• Two wheels bolts and nuts
• Left side and right side elongated axle nuts
• Nut and Bolts for connecting training wheel legs
