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 "Premium" MTB Headset Top Cup - ZS44/28.6 is the top half of the Wolf Tooth Premium headset for frames with a zero stack headset (ZS44: 44 mm head tube inner diameter on top) and a fork with a 1 1/8 inch steerer, machined from 6061 aluminium in Minnesota. Wolf Tooth sells top and lower cups separately, so you replace only the half your frame needs and mix colours freely. Inside is an Enduro stainless steel bearing with a lifetime warranty, an O-ring on the steerer and a lip seal over the bearing keep water out. The stem cap with integrated 5 mm spacer, the aluminium bolt and a star nut are included; a carbon steerer needs a compression plug instead of the star nut. The 6 mm top cover gives a 6 mm stack.
