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.

Carbon rim notice
On carbon rims, single layers of the laminate can crack, usually from hard landings or overloading. Such damage from use is not a defect: it is covered neither by the statutory warranty nor by any manufacturer's warranty. A rim with cracked layers should be checked before it is ridden again.
Our recommendation: carbon rims are best suited to experienced, professional use. Front wheel rather than rear, and park, dirt or race rather than street. Land clean and you keep the weight advantage for longer. Worth being aware of.
