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 Promax "HF-3" BMX Race Crankset is the top of the Promax aluminum crank range. Both arms are hollow forged from 6061-T6 aluminum and CNC machined, which makes them stiff yet light. They spin on a 30mm 7075 aluminum spindle. Chainrings with SRAM 3-bolt direct mount sit right on the arm and save the spider, for classic chainrings a 4-bolt 104 BCD spider is included. Pedal washers are included, the bottom bracket is not: a match is for example the Promax EX-2 with 30mm spindle.
