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 SD Components "BB386 Spinning" BMX Race Bottom Bracket - 24mm is a CNC-machined aluminum bottom bracket in the BB386 standard. It takes a crankset with a 24mm spindle and fits frames with an 86mm shell width and a 46mm inner diameter. The bearings have a conical outer race and only fit one way into the cups, the side marked OUT faces outwards. This aligns the bearings coaxially by itself for a clean power transfer. The SD Components "BB386 Spinning" BMX Race Bottom Bracket - 24mm is installed via the 20-spline internal fitting on both sides, and its threaded design keeps dirt out and makes the bottom bracket stiffer.
