The ZeroRC Hub-W-6-2 is a 22mm adjustable offset metal wheel hub designed specifically for the RW00 series. While the "W-6-1" version typically identifies the primary 5-spoke design with a specific offset or color, the W-6-2 designation often refers to a variation in wheel spoke pattern (such as a multi-spoke or mesh design) or a different base offset range. 
 
Key Features:
 
Stepless Adjustment: Like the rest of the W-6 series, these feature a steplessly adjustable offset (typically ranging from 0mm to +3.5mm). This allows you to precisely align your tires with the fender of any 1/24 or 1/28 body shell.
Material: CNC-machined from 7075 aluminum alloy, providing high durability and reduced rotational mass for better throttle response.
Compatibility: Designed for the ZeroRC RW00 and RW00SR, but fully compatible with other micro-drift platforms like the Kyosho Mini-Z (MR-03), DriftArt, DRZ, and BMR.
Diameter: 22mm, which is the standard competition size for micro-drifting. 
 
Visual Variants:
 
While the "6-1" often refers to a White or Purple set, the 6-2 is frequently associated with different colors or spoke counts: 
Hub-G-6-2: Green 5-spoke rims.
Hub-S-6-2: Chrome 5-spoke rims.
Hub-W-6-2: Typically identifies a White or Silver multi-spoke variant in the metal wheel series.
