9mm Thick Base: The wider 9mm base evenly distributes stress across the freehub, preventing damage under heavy loads. These aluminum single-speed cogs feature extra-tall teeth for reliable chain retention, even with chain tensioners.
Premium Single Speed Cog: Designed with a unique tooth shape, narrow-wide profile, and perfect roundness, these sprockets are built to last longer than other aluminum counterparts.
One-Piece 7075 High-Quality Aluminum Alloy: Unlike most split designs on the market, our one-piece flywheel offers superior strength and lighter weight, weighing only 66g.
Freehub and Chain Compatibility: Compatible with Shimano Hyperglide style freehub body splines (multi-speed or single-speed). Not compatible with Shimano Microspline or SRAM XD freehub bodies. Works with all chains from 7 to 12 speeds.
Versatile Spacers Included: The set includes 2pcs 5mm spacers, 1pcs 7mm spacer, and 1pcs 12mm spacer, providing flexibility for different setups.
