The threaded top caps are usually an aftermarket or more quality fork. The ones that come with a bolt and washer are called compression caps. These are common on mountain bikes and lower level BMX bikes. I will talk about that in my next video.
@@cartracer64 no the diameters are not all the same. Animal and WTP top caps are a bit wider in diameter than say a kink or odyssey’s top cap diameter only by a couple mms, but they are not interchangeable.
