Weight
The heaviness of a BMX part, measured by weighing. It's worth noting that weight specifications for BMX parts can vary and may not always be precise. Several factors contribute to this:Manufacturer's weight specifications may be inaccurate or incomplete.The weight of two identical parts can also differ.We cannot weigh every individual part.For example, if there are handlebars in different heights, the manufacturer usually provides just one weight specification for all heights. When weighing two identical tires, you might get two different results.

The Wolf Tooth "Performance" MTB Headset Lower Cup - ZS56/40 is the lower half of the Wolf Tooth Performance headset for frames with a zero stack headset (ZS56: 56 mm head tube inner diameter at the bottom) and a tapered fork with a 1.5 inch crown race seat (40 mm), machined from 6061 aluminium in Minnesota. Wolf Tooth sells top and lower cups separately so any combination of head tube and steerer can be put together. Inside runs an Enduro black oxide steel bearing with a one year warranty; the crown race with its over-moulded dual lip seal is included and is best installed with the Wolf Tooth installation adapter, which protects the seal.
