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 Rennen "Decimal Threaded" BMX Race Chainring - Black is a CNC machined 4-bolt chainring (104mm BCD) by Rennen for BMX race. The Decimal sizes (e.g. 40.2T or 42.7T) are not literal fractional tooth counts: Rennen machines the pitch circle and tooth profile so that the effective gear ratio sits exactly between two whole tooth counts. This lets you tune your gearing in tenth-of-a-tooth steps, much finer than with regular chainrings. The threaded version has threads directly in the chainring, no nuts needed. The Decimal size is selectable as an option.
