Choosing the right single-speed conversion kit involves matching hub compatibility, gearing options, and installation ease with your bike’s frame and riding style. The following five kits are widely used by riders converting multi-speed hubs to a clean, simple single-speed setup. They cover a range of teeth sizes and hub bodies, and include spacers and lock rings to help center the chain for a smooth pedaling feel. Use this guide to compare compatibility, chain width, and build quality so you can select a kit that suits road, mountain, or dirt-jump applications.

CyclingDeal 16-Tooth Conversion Kit
- COMPATIBILITY: Converts a multi-speed hub to a single-speed wheel. Compatible with Shimano or SRAM 7–11 speed cassette-type hub bodies on mountain and road bikes.
- NOTE: It will NOT convert the hub into a fixed gear; the hub remains a freewheel hub.
- CHAIN SIZE: Sprocket works with chain widths from 1/2″ x 3/32″ to 1/2″ x 11/128″ (7–11 speed chains). Your original chain can be reused in many setups.
- PERFECT CHAIN LINE: Includes single-speed spacers, a lockring, and a sprocket. A range of spacer sizes helps you dial in a precise chain line. A listing video provides installation details.

Buying Guide
Key factors to consider
- Hub compatibility: Confirm your hub body accepts a single-speed sprocket from a multi-speed cassette interface. Most kits target Shimano/SRAM 7–11 speed hubs but can vary by brand and model.
- Gear range and teeth count: Choose teeth size to achieve your desired pedaling cadence and riding terrain. Road riders often prefer higher gearing for speed, while dirt jump and MTB riders may opt for lower teeth counts for torque.
- Chain width compatibility: Ensure the sprocket size matches your existing chain width (commonly 1/2″ x 3/32″ to 1/2″ x 11/128″). Reusing your current chain is possible in many setups.
- Chain line and spacers: A proper chain line improves shifting performance and drivetrain efficiency. Look for kits that include spacers and guide rings to tune alignment.
- Weight and materials: Aluminum cogs are lightweight and resistant to corrosion; some higher-end kits use 7075 aluminum for extra strength.
Compatibility and hub types
- Single-speed conversion kits generally work with freewheel hubs or cassette-body hubs that can accept a single-speed sprocket with spacers.
- Verify if your hub requires a lockring or specific spacer thickness to maintain tension and alignment.
- Road, mountain, and dirt-jump bikes have different chain lines and derailleur clearance; check frame clearance and gear ratios before purchasing.
Installation considerations
- Stock chain length: Some kits allow reusing the existing chain; others may require a new chain if the gear ratio changes significantly.
- Tools needed: You may need a chain whip, lockring tool, or standard bike tools to install spacers and lock rings.
- Instructions and videos: Look for kits that provide installation videos or clear manuals to minimize installation errors.
Materials, weight, and durability
- 7075 aluminum cogs are common for strength-to-weight, reducing wear on the freehub body and prolonging life under rough conditions.
- Base thickness (for example, 9mm bases) can affect load distribution on the freehub; thicker bases can help minimize stress under heavy pedaling.
- Teeth profile (narrow-wide vs. straight) influences chain retention, especially when using chain tensioners or rough terrain.
Use-case comparisons
- Urban commuting: A mid-range 13–16T range offers good versatility while keeping the setup simple.
- Trail and dirt jumps: A wider range (13–22T) provides flexibility for varying terrain and rider strength.
- Road performance: Higher tooth counts (14–18T) paired with precise chain-line spacers can improve cadence at speed.
In short, the best single-speed kit for you balances hub compatibility, desired gearing, and how much you value weight and durability. The five options listed offer a spectrum of teeth counts and hub support to accommodate different bikes and riding styles without requiring a full drivetrain rebuild.
