CyclingDeal Conversion Kit 16T for Shimano/SRAM Hubs
The CyclingDeal 16T conversion kit enables turning a multi-speed hub into a single-speed wheel, compatible with Shimano or SRAM 7 to 11-speed cassette-type hubs on both mountain and road bikes. It does not convert the hub into a fixed-gear hub; the hub remains freewheel compatible. The kit includes a single-speed sprocket, spacers, and a lockring to help achieve a correct chain line. Chain compatibility spans 1/2″ x 3/32″ to 1/2″ x 11/128″ chains, allowing use of the existing chain if desired. A range of spacer sizes helps tailor the chain line for precise drivetrain alignment, supported by on-list instructional video guidance.
This option is well-suited for riders seeking a simple, adjustable gearing setup without extensive modifications. Compatibility with a broad spectrum of 7–11 speed systems makes it versatile for various bikes and terrains.
CyclingDeal Conversion Kit 12T for Versatile Single Speed Setup
This CyclingDeal 12T kit mirrors the 16T option in compatibility, enabling single-speed conversion for Shimano or SRAM hubs with 7–11-speed bodies on mountain and road bikes. It includes single-speed spacers, a lockring, and a sprocket to ensure proper chain line. It’s suitable for riders who want a tighter gear ratio for steeper climbs or sprint-focused riding. By preserving your original chain, you can simplify installation and reduce downtime. Watch the listing video for detailed spacer configurations to achieve the ideal chain alignment.
The kit emphasizes modularity and ease of use, making it a practical choice for riders experimenting with different gearing while maintaining compatibility across a wide range of hubs.
CyclingDeal 13T Conversion Kit for Flexible Gearing
The 13T CyclingDeal kit targets riders seeking mid-range gearing with a similar compatibility profile to the other CyclingDeal options. It supports Shimano and SRAM 7–11-speed hubs on mountain and road bikes, with a complete set of spacers, lockring, and sprocket to ensure a correct chain line. The kit’s versatility helps riders optimize pedaling efficiency across mixed terrain, from rocky ascents to fast, flowy descents. As with the 16T and 12T options, the chain can often be reused, simplifying setup and maintenance.
CooMeng Cog Kit 15T/16T/18T for Durable Single-Speed
The CooMeng cog kit features 15T, 16T, and 18T aluminum single-speed cogs with a wider 9mm base to distribute stress across the freehub, reducing potential damage under heavy loads. Its design emphasizes durability with extra-tall teeth to improve chain retention when using chain tensioners. The one-piece 7075 aluminum alloy construction combines strength with light weight (about 66g). This kit is suitable for riders who want a robust, long-lasting cog assembly with a straightforward installation process, suitable for dirt jumps and aggressive trail riding where reliable chain retention matters.
Buying Guide: Key Considerations for Single-Speed Conversions
- Hub compatibility: Ensure the kit supports your hub’s body type (Shimano/SRAM) and the range of speeds (7–11 speed) it was designed for. Some kits explicitly state they won’t convert to fixed-gear hubs.
- Chain width and length: Confirm your chain size (commonly 1/2″ x 3/32″ to 1/2″ x 11/128″) and whether your current chain can be reused. If not, plan for a suitable replacement.
- Chain line accuracy: A proper chain line minimizes drivetrain cross-talk and wear. Look for kits that include spacers and lockrings to help align the chain correctly.
- Spacer configurations: A kit with multiple spacer sizes offers versatility for achieving an optimal chain line depending on wheel dish and frame geometry.
- Strength and durability: Aluminum cog options may be lighter but require careful maintenance; heavier steel versions can offer greater durability in rugged conditions. Consider your riding style and terrain when choosing.
- Installation complexity: Some kits provide video guides or clear instructions; others rely mainly on the included parts. Choose according to your comfort with wheel work and alignment.
- Compatibility with existing chain: If you plan to reuse your current chain, verify the sprocket tooth count and chain width align with your chain model to avoid premature wear.
- Intended use: For dirt jumps and aggressive trail riding, durability and chain retention become critical; for casual trail riding, a lighter cog may suffice.
