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 e*thirteen "Helix Race 12-speed" Cassette Aluminium Cluster - 43-52T is the aluminium cluster with the two largest cogs (43 and 52 teeth) of the two-piece Helix Race 12-speed cassettes 9-52 and 13-52. Unlike one-piece cassettes you only replace the worn part with e*thirteen: the steel cluster stays, the aluminium cluster is swapped, which makes running costs a lot lower. The 43-52 cluster also fits the steel cluster of a Helix or TRS Plus 9-50 cassette and turns it into a 9-52. Check chain wear when swapping; from 0.5 % elongation e*thirteen recommends a new chain, or the new cluster suffers. Colour naranja (orange).
