CyclingDeal Conversion Kit Fixie Bike Single Speed

The CyclingDeal kit converts a multi-speed hub to a single-speed wheel, compatible with Shimano or Sram 7 to 11 speed cassette type hub bodies, suitable for both mountain and road bikes. Note that it does not convert the hub to a fixed-gear setup; the hub remains a freewheel hub. The sprocket supports chain widths from 1/2″ x 3/32″ to 1/2″ x 11/128″ (7–11 speed chains), allowing you to reuse your original chain. A selection of sprocket teeth options helps you dial in the perfect pedaling ratio. The package includes single-speed spacers, a lockring, and a sprocket, with various spacer sizes to align the chain line precisely. A video in the listing provides additional setup guidance.
Features include compatibility across popular hub bodies, a range of sprocket teeth selections, and a complete chain-line solution, making it a practical choice for riders aiming to convert versatility into a clean, single-gear ride.
CyclingDeal Conversion Kit Fixie Bike Single Speed

This kit mirrors the prior CyclingDeal option with the same core compatibility and chain-line design. It supports conversion from a multi-speed hub to a single-speed wheel, retaining the freewheel hub design. The chain width compatibility covers 1/2″ x 3/32″ to 1/2″ x 11/128″ chains, ensuring broad chain compatibility for 7–11 speed systems. Choose from a range of sprocket teeth to fine-tune pedaling efficiency. Included spacers, a lockring, and a sprocket set help achieve a precise chain line, with video guidance for installation clarity.
Potential use cases include riders who want improved simplicity, reduced maintenance, and a clean, minimalist drivetrain on road or mountain bikes. The kit’s versatility makes it suitable for riders transitioning from multiple gears to a single speed without replacing the entire hub assembly.
Bibike Single Speed Conversion Kit 13T/14T/15T/16T/17T/18T/20T/22T

This Bibike kit is designed for Shimano or Sram 8 to 11 speed HG cassette bodies on both mountain and road bikes. It accommodates chain widths from 1/2″ × 3/32″ to 1/2″ × 11/128″ (6–11 speed chains). The package includes a 16T cassette, spacers (10mm, 5mm, 3.7mm, 2mm), and a lock ring, providing a complete set for configuring a single-speed drivetrain. The assortment of spacers supports precise chain-line alignment and compatibility with various hub bodies, enabling a straightforward conversion for riders seeking a simple gear setup.
Bibike Single Speed Conversion Kit 13T/14T/15T/16T/17T/18T/20T/22T (Alternate)

This Bibike listing mirrors the first Bibike kit but features an alternate selection of sprockets, providing similar 6–11 speed chain compatibility. The kit includes a 17T cassette, spacers (10mm, 5mm, 3.7mm, 2mm), and a lock ring to ensure a robust, reliable single-speed setup. The spacers enable precise chain-line tuning, helping maintain efficient pedaling and smooth shifting between different wheel configurations. Suitable for riders seeking a broad range of gearing options for urban, trail, or mixed-terrain use.
15T/16T/18T Single Speed Cogs Conversion Kit

Built for multi-speed bikes converting to dirt jump or BMX setups, this aluminum single-speed cog kit emphasizes durability and retention. The base is 9mm thick to distribute stress across the freehub, reducing the risk of damage under heavy loads. The one-piece 7075 aluminum alloy flywheel offers strength with lighter weight, and the sprockets feature a narrow-wide tooth profile for reliable chain retention even with chain tensioners. The set weighs about 66g and is designed to provide long-lasting performance in demanding riding conditions, with compatibility aimed at single-speed conversions where weight and strength matter most.
Buying Guide: Key Purchase Considerations
- Hub compatibility: Verify if the kit supports Shimano or Sram hubs and whether your hub is a cassette-type or freewheel type. Several kits specify compatibility with 7–11 speed cassette bodies and note when a hub cannot be converted to fixed-gear.
- Chain width and tooth options: Ensure the sprocket teeth count matches your desired gearing and that the chain width (commonly 1/2″ x 3/32″ to 1/2″ x 11/128″) is compatible with your existing chain.
- Chain line precision: Look for kits that include spacers and a lockring to achieve a true single-speed chain line, reducing chain rub and improving drive performance.
- Weight and material: Aluminum cogs offer lightness and durability; consider the balancing of weight vs. strength for your riding style, especially for BMX or dirt-jump use.
- Installation resources: Video guides or included instructions can greatly simplify the setup, particularly for spacers and alignment.
- Intended riding type: Road, mountain, BMX, or dirt-jump applications influence the sprocket range and base design. For example, wider spacers support robust chain retention under heavy loads.
- Maintenance considerations: Single-speed setups reduce shifting components but require periodic checks for chain tension, chain line, and cog wear to maintain efficiency.
Overall, selecting a single-speed conversion kit involves understanding hub compatibility, gearing range, chain compatibility, and the alignment tools included. The products above provide a range of options—from general, versatile kits to model-specific cogs—allowing riders to choose a solution that best fits their bike and riding discipline.
