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.Source: BMX Glossary

The Marin Bikes "Alcatraz 2" MTB Frame - 26 Inch is Marin's dirt jump frame with a geometry fine-tuned by Matt Jones. The Series 3 frame made of 6061 aluminum has short chainstays for poppy manuals and a low standover, and the cables run internally. Horizontal 135 x 10 mm dropouts with Marin's chain tension device, a 73 mm BSA bottom bracket and ISCG 05 tabs for a chain guide are part of it, as are the FSA headset and the seat clamp that come in the box. There are two sizes: Short keeps you close to your BMX roots, Long rides calmer and is made for taller riders.
