I repair a lot of old bikes and repair children's bikes. Without exception, there is no ball bearing in the headset cage or in the wheel hub. I can easily match them with these free bearings and glue them in place. I have used these bearings for this purpose at least 5 times in the past few weeks. I need another box soon. Hope that helps!
