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 "CK-1 Carbon" BMX Race Crankset is the lightest crankset from Promax: the crank arms are carbon, the beefy 30mm spindle is permanently fitted in the left arm and keeps the drivetrain stiff when you sprint. Chainrings mount directly (direct mount, SRAM 3-bolt), which saves the spider. If you want to run 4-bolt chainrings with a 104mm BCD, the matching Promax spider is available separately. Pedal washers and three bolts for spider or chainring are included, the bottom bracket is not. Choose the crank length as an option.
