CyclingDeal 16T Single Speed Conversion Kit
This CyclingDeal kit enables a multi-speed hub to become a single-speed wheel. It is compatible with Shimano or SRAM 7 to 11 speed cassette-type hub bodies, for both mountain and road bikes. Important to note: the kit does not convert the hub into a fixed-gear setup—the hub remains a freewheel hub, preserving coast and glide functionality. The sprocket supports chain widths from 1/2″ x 3/32″ to 1/2″ x 11/128″ (7–11 speed chains), so you can reuse your existing chain rather than purchasing a new one. This flexibility helps riders maintain gearing without a major overhaul of the drivetrain.
With a 16-tooth option, you can tailor your pedaling ratio to your local terrain, whether you’re tackling hills, urban climbs, or longer flats. The kit includes a set of single-speed spacers, a lockring, and the sprocket, plus spacer sizes that help achieve a straight chain line across a range of hub widths. The packaging suggests watching the listing video for setup details, which can be a helpful reference for first-time installers. In practice, this kit offers a straightforward path to a clean, reliable single-speed configuration on compatible hubs.
CyclingDeal 12T Single Speed Conversion Kit
This variant from CyclingDeal provides a 12-tooth single-speed sprocket intended for converting a multi-speed hub into a dedicated single-speed wheel. Like the 16T version, it targets Shimano or SRAM 7–11 speed cassette-type hubs, appropriate for both mountain and road bikes. It does not convert the hub into a fixed-gear arrangement, preserving the freewheel behavior for coastability. It accepts the same chain widths as the 16T kit (1/2″ x 3/32″ to 1/2″ x 11/128″), allowing you to maintain your current chain if it fits your preferred gear ratio. The included spacers and lockring help you achieve proper chain alignment during installation.
The 12T option allows even lower gearing, which can be advantageous for riders who prefer easier climbs or smoother acceleration at slower speeds. As with the 16T version, the kit is designed to be user-friendly with spacer variations to help dial in the chain line. Review the listing video for installation guidance and ensure your hub matches the described compatibility before purchasing.
Hycline 16T Freewheel
The Hycline 16T Freewheel offers a threaded, screw-in design that makes it a straightforward replacement for compatible freehub bodies. It uses a 16-tooth cog, compatible with 1/2″ x 1/8″ chains, and features an inner diameter around 34.1mm with a thread pitch of 1.375mm. Made from high-tensile steel, this cog emphasizes durability and smooth rotation. The installation process is described as screwing in the freewheel, with the caveat that achieving a perfect balance may require some attention to thickness alignment to maintain proper chain line. This option suits riders seeking a simple, robust single-speed cog without spacers or adapters.
Key advantages include strong metal construction and precise threading, which contribute to reliable performance under varied riding conditions. Potential trade-offs involve the need to ensure chain line compatibility on a given hub and proper deburring or alignment during install. For riders mainly interested in a fixed, low-maintenance cog that fits threaded freewheels, this Hycline model provides a solid option with clear installation steps and durable materials.
CyclingDeal 13 Teeth Single Speed Kit
This CyclingDeal option offers a 13-tooth single-speed sprocket compatible with multi-speed hubs to create a dedicated single-speed configuration. It shares the same compatibility scope as other CyclingDeal kits, working with Shimano or SRAM 7–11 speed cassette-type hub bodies for mountain and road bikes. The kit emphasizes that the hub remains non-fixed gear; once installed, it functions as a standard single-speed wheel with chain width compatibility from 1/2″ x 3/32″ to 1/2″ x 11/128″. The included spacers and lockring aid precise chain line alignment when adjusting the setup for your frame. As with its peers, a video guide in the listing can assist during installation.
With a range of tooth options, this kit supports dialing in gearing to meet riding preferences, whether for urban commutes or light trail use. The combination of spacers and lockring helps ensure the chain line stays straight as the chain tension changes with gear selection and wheel alignment. This model is a practical option for riders who want a middle-ground gearing step with straightforward installation steps and tested compatibility with common hubs.
Bibike 16T Single Speed Cassette Kit
The Bibike 16T kit is designed for Shimano or SRAM 8–11 speed HG cassette bodies on mountain and road bikes. It accepts chain widths from 1/2″ x 3/32″ to 1/2″ x 11/128″, accommodating a range of riding setups. The package includes a 16T cassette plus spacers: 10mm, two 5mm, a 3.7mm spacer, a 2mm spacer, and a locking ring. This kit is ideal for riders looking to convert to a clean, reliable 16T single-speed configuration with a complete spacer set to help achieve proper chain line and tension. Installation may require basic hub and wheel work, but the included hardware supports straightforward setup.
Because it includes a complete spacer stack, the Bibike 16T kit offers a practical balance between gearing options and installation flexibility. It’s suitable for riders who want a ready-to-install solution with all necessary components included, minimizing the need for additional purchases. As with any conversion kit, confirm hub compatibility and measure chain line expectations before committing to the upgrade for your specific bike frame and drivetrain layout.
CooMeng 15/16/18T Single Speed Cogs
The CooMeng conversion kit presents 15T, 16T, and 18T single-speed cog options, designed for multi-speed bikes converting to dirt jump or BMX-style single-speed setups. A key feature is the 9mm thick base, which distributes stress across the freehub to reduce potential damage under heavy loads. The cogs use a premium one-piece 7075 aluminum alloy, offering a strong yet lightweight alternative to split designs. Weighing about 66g, these cogs emphasize durability while keeping overall weight down. The kit highlights a narrow-wide tooth profile for reliable chain retention and a robust overall construction intended for aggressive riding patterns.
While the 9mm base and one-piece design contribute to improved durability, users should verify compatibility with their specific freehub and chain line. The tool-free assembly is generally straightforward, but some setups may require careful alignment with spacers and locking rings to ensure optimal performance. For riders seeking a lighter, sport-oriented cog with strong retention features, the CooMeng option provides a compelling balance of weight, strength, and gearing flexibility across 15T–18T teeth counts.
Buying Guide
Choosing a single-speed upgrade involves weighing drivetrain compatibility, gearing needs, and installation practicality. Start by confirming hub compatibility: most kits target Shimano or SRAM 7–11 speed cassette-type hubs, suitable for mountain and road bikes. If your hub is a true freewheel or has a different interface, some options may not be compatible. Be mindful that many conversion kits do not convert hubs into fixed-gear setups; they create a dedicated single-speed configuration while preserving coast and freewheeling functionality.
Gear teeth options matter. A wider range (e.g., 12T to 16T or 15T–18T) lets you tailor gearing for varied terrain. Consider your typical riding environment—hills, flat commutes, or mixed terrain—and select a tooth count that provides an efficient balance between cadence and leg effort. Also check chain width compatibility (commonly 1/2″ x 3/32″ to 1/2″ x 11/128″), since using an incompatible chain can cause poor shifting, noise, or chain drop.
Chain line and spacers are important. Most kits include spacers and a lockring to achieve a straight chain line, but the exact spacer set must align with your frame width and hub spacing. If a kit advertises a video guide, watch it to understand the recommended spacers and alignment steps for your bike. Weight considerations vary by material; aluminum cogs are typically lighter, while steel versions may offer different durability profiles. For lightweight, aggressive riding, consider a one-piece aluminum cog with a narrow-wide tooth design that helps retain the chain under heavy loads.
Installation complexity ranges from straightforward to moderately technical. Some kits include everything needed for a quick swap; others may require additional tools or wheel work. If you’re unsure, seek guidance from a bike shop or consult the listing’s installation video. Finally, compare long-term value: a kit that offers multiple tooth options, durable materials, and reliable chain-line alignment may justify a higher upfront cost by reducing maintenance and downtime over the season.
