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 Pride Racing "Newton SX Pro" BMX Race Cranks is a two-piece BMX race crank made from forged and then CNC-machined 7-series aluminum with a 24mm heat-treated CrMo spindle. Pride designed the arms with finite element analysis and forges them in a waffle structure, so the wall thickness stays consistent and the arms resist lateral flex at a low weight. The 168mm Q-factor and 43.5mm chainline are set up for racing, the chainring sits on a 4-bolt spider with 104mm BCD and is swapped quickly through the four integrated chainring bolts. The Pride Racing "Newton SX Pro" BMX Race Cranks fits BB86 and BSA 68/73mm bottom brackets, comes in five lengths from 170 to 180mm, weighs 738g in 175mm and is rated for riders up to 120kg. One compression bolt, two pinch bolts and four chainring bolts are included.
