CyclingDeal Conversion Kit 12T for Multi-Speed Hubs
The CyclingDeal 12-tooth single speed cog assembly is designed to convert a multi-speed hub to a single-speed wheel on mountain and road bikes. It is compatible with Shimano and Sram 7 to 11 speed cassette hub bodies. Note that this kit does not turn the hub into a fixed-gear hub; the hub remains a freewheel type. The included sprocket supports chain widths from 1/2″ x 3/32″ to 1/2″ x 11/128″ (7–11 speed chains). A range of sprocket teeth options allows you to fine-tune your pedaling ratio. The kit also provides spacers, a lockring, and a sprocket to help achieve an ideal chain line. For best results, watch the listing video for setup details.
CyclingDeal Conversion Kit 16T for Multi-Speed Hubs
This CyclingDeal kit provides a 16-tooth single-speed sprocket and the necessary spacers to align the chain line on Shimano or Sram 7–11 speed hub bodies. It is suitable for both mountain and road bikes, featuring the same notes as the 12T version: it does not convert to a fixie hub, chain width compatibility from 1/2″ x 3/32″ to 1/2″ x 11/128″, and includes a lockring and spacers for precise alignment. View the listing video for complete installation guidance and chain line optimization tips.
CooMeng 15T/16T/18T Single Speed Cog Kit
This CooMeng single-speed cog kit features 9mm thick bases that distribute stress evenly across the freehub, reducing potential damage under heavy loads. The gear cogs use a premium single-speed design with a narrow-wide tooth profile for reliable chain retention, even when using chain tensioners. Made from one-piece 7075 aluminum, the flywheel is strong and lightweight (about 66 grams). A great option for dirt jump or BMX-style bikes that require durable, lightweight cogs with solid chain retention.
Bibike 13T–22T Single Speed Cassette & Spacers
The Bibike kit covers a broad tooth range from 13T to 22T, suited for Shimano or Sram 8 to 11 speed HG cassette bodies on both mountain and road bikes. It supports chain widths from 1/2″ x 3/32″ to 1/2″ x 11/128″ and includes a 17T cassette, spacers in multiple thicknesses (10mm, 5mm, and 3.7mm), plus a lock ring. This set provides enough components to configure a reliable single-speed drivetrain with multiple gearing options to suit various riding styles. An ideal choice for riders seeking flexibility without sacrificing simplicity.

Ideal for riders who want multiple gearing options within a simple, low-maintenance configuration.
Buying Guide: Key Factors for Choosing a Single Speed Conversion Kit
- Compatibility: Confirm hub compatibility with your current cassette type (Shimano or Sram) and ensure the kit supports 7–11 speed hubs. Note whether the kit changes the hub type (freewheel vs. fixed) and whether a fixed-gear conversion is possible.
- Chain Line and Spacers: Look for kits that include spacers in multiple sizes to achieve a precise chain line. A proper chain line reduces chain drop and wear on the sprocket and chain.
- Cog Teeth Range: Choose a range that matches your preferred pedaling ratio and riding style. A broader range (13T–22T) offers more gearing flexibility for flats, hills, and different terrains.
- Materials and Weight: Aluminum (especially 7075 aluminum) cogs are lightweight yet strong, providing good durability for street and trail riding. Heavier options may be more affordable but can affect performance.
- Installation Ease: Kits that come with lock rings, spacers, and clear instructions simplify installation. Some listings may include installation videos; these can be valuable for first-time converters.
- Durability and Retention: Look for features like narrow-wide tooth profiles and tall teeth to improve chain retention, particularly if you ride with tensioners or rough terrain.
- Multiple Listings: Some brands offer the same kit in multiple listings. If you shop across listings, confirm the included components match your needs (spacers, lock ring, and sprocket).
- Maintenance and Availability: Consider the availability of replacement parts (spacers or cogs) in case you need to tailor gearing or replace components after wear.
- Use Case: For urban commuting, a lighter, compact cog set with a narrower gear range may suffice. For trail riding or dirt jumps, a wider range and robust construction can be more appropriate.
When selecting a single speed conversion kit, align your choice with your riding goals, wheel compatibility, and the ability to fine-tune chain alignment. Each of the listed options offers a balance between durability, gearing flexibility, and installation practicality, helping you achieve a reliable, low-maintenance single-speed setup.
