CooMeng 15T/16T/18T Single Speed Cogs Conversion Kit for Multi-Speed Bike to Dirt Jump/BMX, Aluminum Single Speed Cassette with Spacer and Locking

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. Upgrade your multi-speed bike with the 15T/16T/18T Single Speed Conversion Kit.
