Buying Guide: Key Considerations For Single Speed Hubs
- Hub spacing and width: Most single-speed setups use 135mm rear spacing; verify compatibility with your frame and overall wheel build.
- Threading and axle type: Common threads are 3/8″ for hubs, but some hubs use alternative threads or double-thread designs. Check the freewheel or fixed gear compatibility and whether you need a standard axle or quick-release.
- Hub type: Choose between coaster brake, freewheel, or fixed-gear hubs. Coaster brakes integrate braking into the rear hub, while fixed-gear hubs require a separate brake system if needed for safety.
- Bearings and seals: Sealed cartridge bearings reduce maintenance and provide smooth rotation, especially in muddy or wet conditions. Consider shielded or sealed options for longevity.
- Disc compatibility: If you want modern braking performance, a hub with a 6-bolt disc mount can allow you to add disc brakes, though this is more common on geared hubs than traditional fixed or single-speed setups.
- Spoke count and wheel build: A 36-hole hub works with many common rims and spoke counts, but confirm compatibility with your planned rim and lacing pattern.
- Conversion vs. direct hub: For riders upgrading from multi-speed wheels, conversion kits can enable single-speed operation, but ensure the hub body can accept a single-speed sprocket and maintains proper chain line.
- Weight and materials: Aluminum hubs offer a good balance of strength and lightness for daily riding, while steel hubs can be more affordable but heavier.
- Intended use: Dirt jumps, urban commuting, or road use each benefit from different hub features like engagement, stiffness, and durability.
- Maintenance: Regular lubrication of bearings and inspection of spoke tension help preserve performance and wheel life.
When selecting a single speed rear hub, align your choice with your riding style, frame compatibility, and maintenance tolerance. If you plan to convert a geared hub, ensure the kit’s components provide a precise chain line and secure mounting. For fixed-gear setups, confirm that the hub or kit supports a stable, direct drive with dependable braking options if required.
