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 Reverse Components MTB Stem Shim turns a 35 mm stem clamp into a 31.8 mm one. The two half shells go into the stem before the handlebar, then the face plate is tightened as usual. It is the cheap answer to a stem you want to keep and a handlebar that does not match it. Made from aluminium, the extra weight is negligible, and because the shells spread the clamping force over the full width, the load on the bar stays the same as with a matching clamp.
