CyclingDeal Conversion Kit Fixie Bike Single Speed
The CyclingDeal kit is designed to convert a multi-speed hub to a single-speed wheel. It fits Shimano or Sram 7 to 11-speed cassette-type hub bodies for mountain and road bikes. It explicitly notes that the hub remains a freewheel hub and will not transform into a fixed gear. This kit includes spacers, a lockring, and a sprocket, enabling a customizable chainline. Best for riders who want a simple, flexible conversion without replacing the entire wheelset. A potential limitation is the need to verify precise hub compatibility for your bike model.
Why choose this for your build?
- Best for riders converting existing multi-speed wheels to a clean single-speed setup.
- Better when you want to maintain compatibility with your current chain and drivetrain layout.
- Clear step-by-step adjustment via included spacers for a correct chain line.
PeakRider Single Speed Conversion Kit for Shimano HG Freehub
This PeakRider kit targets Shimano HG freehubs, covering standard 7–12 speed bodies. It includes a CNC 7075 aluminum single-speed cog with spacers (5mm, 7mm, 12mm) for a complete conversion. The design emphasizes a solid, one-piece cog that resists shifts and drops while maintaining a strong chain line. Not compatible with Microspline or SRAM XD drivers. The 9mm-thick base helps distribute pedaling forces and protect the freehub, offering longevity and smoother engagement compared to lighter aluminum designs.
Best for this type of application?
- Best for riders using Shimano HG hubs who want a durable, stable single-speed cog.
- Choose this if you value a rigid, one-piece cog that minimizes chain drops and improves pedaling efficiency.
PeakRider Single Speed Conversion Kit for Shimano HG Freehub
This variant mirrors the HG freehub compatibility and includes the same CNC 7075 aluminum cog and spacer set. It is designed to deliver a secure, precise chain engagement with narrow-wide teeth. The kit’s broad compatibility makes it suitable for a wide range of 7–12-speed hubs, providing a straightforward path to a true single-speed ride. A note: ensure your hub is compatible with the listed freehub type before purchasing.
Best for this scenario?
- Best for riders with Shimano HG freehubs seeking a robust conversion cog and reliable performance.
- Avoid this if your bike uses Microspline or SRAM XD drivers.
PeakRider Single Speed Conversion Kit for Shimano HG Freehub
This is another PeakRider option for Shimano HG freehubs, offering the same 7075 aluminum cog and spacers to create a precise single-speed setup. The emphasis remains on durability, torque resistance, and reliable chain retention. It shares the same compatibility caveat as the other PeakRider HG kit and is best viewed as an interchangeable option when a specific cog size or spacer combination is needed for your bike geometry.
When to pick this variant?
- Choose this if you need the same rugged construction but want to select a different cog-spacer configuration.
- Best for riders balancing cadence with a fixed-gear feel on a Shimano hub.
Bibike 10 Speed MTB Groupset
The Bibike group comprises a 10-speed chain, an 11-50t cassette, a 1×10-speed rear derailleur, and a shifter. It is designed for 1x configurations on mountain bikes and includes a compact 11-50t range. The cassette range offers a versatile gear spread suitable for mixed terrain. The included 116-link chain has a standard 1/2″ x 11/128″ width. This is best for riders who want a complete upgrade with a single-choice drivetrain, simplifying maintenance and shifting. A possible limitation: weight and compatibility should be checked against specific frame and wheel setups.
Who should consider this group?
- Best for riders upgrading or building a dedicated 1x MTB drivetrain from a full groupset.
- Better for those who want an all-in-one solution rather than assembling parts separately.
Buying Guide: Key Considerations For 1x Conversion And MTB Drivetrains
What hub and compatibility should I verify?
Confirm hub type and speed compatibility (7–12 speed range) before purchasing a conversion kit. Some kits fit Shimano HG freehubs, others require specific hub body types. Incorrect compatibility can lead to fitment issues or poor performance.
Which chainring and cog size work best?
For 1x setups, common combinations include 30T–34T on the chainring with 11–34T to 42T cassettes, depending on terrain and cadence preference. Narrow-wide chainrings improve chain retention on rough trails. Select cog size to balance climbing ability with top-end speed.
What about chainline and spacers?
Proper chainline prevents rubbing and drivetrain wear. Kits often include spacers to fine-tune the chainline. Follow included instructions and ensure correct spacer configuration for your wheel’s dropout width and frame geometry.
Durability and material choice considerations
Look for cogs and chains made from high-strength aluminum (7075) or alloy for durability under aggressive riding. A solid base and precision tooth profile contribute to smoother engagement and longer life on rough trails.
Installation complexity
Single-speed conversions typically require basic bike maintenance skills, including removing a cassette and installing spacers. Some kits are straightforward, while others demand careful measurement for chainline and tension. If unsure, consult a professional mechanic to avoid misalignment.
Limitations to watch for
- Not all kits fit every hub type or frame; verify compatibility before ordering.
- Some kits are not suitable for fixed-gear use or certain driver types.
- Weight and bulk may increase with complete groupsets; assess whether a full upgrade or a targeted conversion better meets your goals.
Practical comparison tips
- Choose CyclingDeal for broad hub compatibility and a complete conversion package.
- Prefer PeakRider for Shimano HG hubs when seeking a rugged aluminum cog and customizable spacers.
- Use Bibike if you want an all-in-one upgrade with a 10-speed MTB gearing range.
- Consider Ganopper crank options if you need to optimize for a clean 1x chainring setup in the crankset area, though these are not a conversion kit themselves.
Frequently asked questions
- Can I convert any bike to 1x with these kits? Most bikes can, but hub compatibility and frame clearance must be checked.
- Is a full groupset necessary for a 1x conversion? Not always; single components can enable a 1x setup, but a complete groupset can simplify compatibility.
- Will a 1x setup affect shifting performance on hilly terrain? A well-maired 1x setup can improve reliability in rough terrain by reducing chain drops and maintenance.
- Do these kits require professional installation? Basic installations are feasible for DIY enthusiasts; more complex configurations may benefit from a bike shop.
- Are these kits compatible with road bikes? Some kits cover road and gravel hubs; always verify hub body compatibility and chainline requirements.
- What maintenance is needed after a 1x conversion? Regular chain lubrication, tension checks, and occasional spacers recheck help maintain performance and longevity.
