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 Surly "Karate Monkey" MTB Frame + Fork Set - 27.5/29 Inch is Surly's versatile hardtail for all sorts of terrain and a canvas for almost any build.

Dropper post compatibility, a 44 mm head tube, Gnot-Boost spacing, thru axles and a suspension corrected fork make it compatible with most mountain bike standards, perfect for the parts bin.
