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 JRC Components "Kizuna" Centerlock Lockring - Internal 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 internal spline is torqued to 40 Nm with a 12-spline Shimano/SRAM cassette tool (e.g. Park Tool FR-5.2); with a 40 mm outer diameter and 3 mm flange it is the slim version for hubs with 12 mm thru axles and QR where an external spline lockring has no room. For 15 and 20 mm thru axles there is the external 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.
