Jurtmy Single Speed Rear Hub for Dirt Jump Bikes
Best for aggressive dirt jump and park riders who need a robust rear hub with reliable sealing. This hub uses 32 spokes and a 6 pawl disc mounting for stability on rough landings. Full sealed cartridge bearings minimize maintenance and keep rotation smooth over time. It is designed for 10x135mm spacing, making installation straightforward on many dirt jump frames.
Who it’s best for: riders who prioritize durability and predictable performance in harsh environments. Why selected: strong 32‑hole/6‑pawl construction and sealed bearings reduce maintenance and improve longevity under jumps. Caution: ensure your frame supports 10x135mm spacing and disc brake compatibility before purchasing.
Shimano Tiagra RS400 10/11-Speed 36h Rear Hub
Best for road cyclists integrating disc braking with 130mm quick‑release rear hubs. This hub features conical races ground by CBN tooling for smooth rolling and reduced maintenance, plus internal o‑rings and a grease sleeve to improve lubrication retention. It’s designed for road setups and is most compatible with 130mm QR dropouts rather than dirt jump frames.
Who it’s best for: road riders seeking smooth, long‑lasting performance with low maintenance. Why selected: precise manufacturing and lubrication design support durability. Caution: not ideal for most dirt jump or single‑speed BMX frames due to geometry and spacing differences.
Dirt Jump Rear Hub 32H/36H with 14T Freewheel
Best for dirt jump bikes that run single speed with a 14T freewheel and need a robust 32H/36H disc brake hub. The fat shell design targets dirt jump/BMX frames with lockout screws and a weight around 526g. It supports internal locking features for secure wheel setup and stable disc alignment.
Who it’s best for: riders building or upgrading a dirt jump bike to a single‑speed system. Why selected: combination of a solid shell, 14T freewheel compatibility, and internal screws for locking stability. Caution: verify spoke count compatibility with your wheel build (32H vs 36H).
Oceanialend 36 Hole Rear Hub with 16T Flywheel
Best for classic fixed or single‑speed builds seeking a simple flywheel approach. This hub provides a 36‑hole configuration and includes a 16T flywheel, making it suitable for older school bikes or riders who want a straightforward, low‑maintenance single‑speed setup.
Who it’s best for: riders who appreciate a traditional single‑speed drivetrain and a ready‑to‑ride flywheel. Why selected: includes 16T flywheel for immediate use. Caution: 36H hubs require compatible wheel builds and may limit spoke pattern choices on some frames.
BMX/Dirt Jump Front Hub Reference
Best for front hub reference when planning a complete wheelset for a dirt jump bike. While not a rear hub, this front hub offers 32H, disc brake compatibility, and a 15x100mm Thru Axle option. It helps ensure balanced wheel performance with your chosen rear hub.
Who it’s best for: riders assembling a full wheelset with a matched front hub. Why selected: provides compatibility context for disc brake setups and hub spacing. Caution: front hub specifications may not directly translate to rear hub compatibility.
Buying Guide: Key Purchase Considerations
- Rear spacing: Most single speed dirt jump setups use 10x135mm. Confirm your frame’s dropout width and axle type (QR vs. thru-axle) before buying.
- Disc brake compatibility: Check if your wheelset supports 6‑bolt disc rotors or centerlock. The hubs above reference 6‑bolt compatibility in many cases.
- Bearings and maintenance: Sealed cartridge bearings reduce maintenance and help long‑term performance in dusty environments. Consider service availability and replacement bearing options.
- Hole count and freewheel: 32H is common for dirt jump hubs; some models offer 36H. If you use a single‑speed freewheel, ensure the hub supports your cog count and threading (14T vs. others).
- Weight vs. durability: Heavier hubs with robust shells often withstand jumps better but may affect acceleration. Balance your riding style with hub construction.
- Compatibility with frames: Some hubs are optimized for BMX or dirt jump geometry. Verify that the hub’s axle type, flange spacing, and disc mount align with your frame.
- Install and maintenance: Look for sealed bearings and easily accessible service parts. A hub with straightforward dismantling is advantageous for field maintenance.
Frequently Asked Questions
