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 JRC Components "Kizuna" Centerlock Lockring - External Spline holds a centerlock rotor on the hub and carries the machined Pathway pattern of the JRC headset top caps: CNC machined from 7075-T6 aluminium, anodised, with a stainless steel shim washer. The external spline is torqued to 40 Nm with a 16-notch 44 mm bottom bracket tool (e.g. Park Tool BBT-69.4) and fits hubs with 12, 15 and 20 mm thru axles and QR. The 4 mm thick flange with 44 mm outer diameter is the standard on MTB forks and frames; where clearance is tight there is the internal spline version. The 100 spline interface matches centerlock rotors from Shimano, Campagnolo and most SRAM rotors, not the Campagnolo/Fulcrum AFS system. Sold individually, in nine anodised colours.
