- 【Reinforced 9mm Thick Base for High Load Use】9mm thick base design distributes stress evenly across the freehub body, helping prevent spline damage under hard riding. Extra-tall teeth improve chain retention, even when used with chain tensioners.
- 【Precision Tooth Profile for Reliable Engagement】Engineered with a dedicated single-speed tooth shape and precise roundness to ensure smooth chain engagement and reduced wear, offering longer service life than typical aluminum cogs.
- 【One-Piece 7075 Aluminum Construction】CNC-machined from one-piece 7075 aluminum alloy, delivering an excellent balance of strength and weight. No split or bonded structure. Approx. 66g per cog for lightweight builds.
- 【Freehub & Chain Compatibility】Compatible with Shimano Hyperglide (HG) style freehub bodies for multi-speed or single-speed hubs. Not compatible with Shimano Microspline or SRAM XD drivers. Works with 7–12 speed chains.
- 【Spacer Kit for Flexible Chainline Setup】Includes 2 × 4.5mm spacers, 1 × 6.5mm spacer, and 1 × 12mm spacer, allowing fine adjustment of chainline for different frame and hub combinations.
