Best Single Speed Conversion Kit for HG and XD/XDR Hubs

#1 · Best Overall

1. Bibike Single Speed Kit

• Weight: 78.6 g
• Material: Alloy Steel, Aluminum

Best for: Broad Chain Compatibility.

Why it ranks #1: Fits Shimano or SRAM 8–11-speed HG bodies, includes multiple chain-line spacers, and is listed with cog sizes from 13T to 22T.

A choice of sprocket sizes from 13T to 22T gives this Bibike kit room to tune gearing for different riding needs. Its HG-body compatibility spans Shimano or SRAM 8–11-speed cassette bodies, while support for several chain widths makes it relevant to a range of existing drivetrains.

The package includes a 17T cassette plus 10mm, 5mm, 3.7mm and 2mm spacers, so the stack can be arranged to adjust chain line rather than relying on a single spacer thickness. The cassette is high-resistant stainless steel, while the spacers and lock ring are 6061 aluminum alloy. At 78.6g total, it adds a listed weight for buyers considering a conversion; compatibility is limited to HG cassette bodies.

Skip it if you have an XD/XDR freehub; the Wheels Manufacturing SOLO-XD kit is specifically listed for that interface.

Choose this kit if your Shimano- or SRAM-compatible HG wheel and chain width fall within its listed range, and you want several sprocket and spacer options. Its defining boundary is HG cassette-body compatibility.

#2 · Best Spacer Range

2. Origin8 Single Speed Kit

• Weight: 10.08 oz
• Material: Multiple
• Warranty Description: Original Manufacturer Warranty

Best for: Adjustable Chain-Line Setup.

Why it ranks #2: Converts a cassette hub using Shimano-style cassette bodies and includes eight anodized 6061 alloy spacers, including conical spacers.

Eight spacers in various sizes give the Origin8 kit its clearest advantage: room to adjust chain line when converting a cassette hub to single speed. Its anodized 6061 alloy construction and new conical spacers add a stiffness-focused detail around the cog.

The kit fits Shimano-style cassette bodies and includes eight spacers, allowing the cog position to be adjusted for chain line rather than fixed at one arrangement. Origin8 specifies anodized 6061 alloy, and describes the conical spacers as increasing cog stiffness. The supplied description references 16T and 18T components, while the listing does not detail individual spacer thicknesses; buyers should therefore weigh its broad adjustment approach against their specific setup.

Skip it if you need a listed XD/XDR fit; Wheels Manufacturing’s SOLO-XD kit names XD/XDR compatibility.

Pick this for a Shimano-style cassette hub conversion where multiple spacer sizes and conical spacers are useful. The supplied information gives a 16T/18T reference but not detailed spacer thicknesses, so account for that in setup planning.

#3 · Best Steel Cog

3. Reverse Single Speed Kit

• Weight: 1 g
• Material: Multiple

Best for: 13T CrMo HG Conversion.

Why it ranks #3: Its CrMo 13T cog fits a normal HG freehub, with seven aluminum spacers for chain-line tuning and an alloy lock ring.

A 13T chromium-molybdenum cog gives the Reverse Components kit a specific, compact gearing choice for an HG freehub conversion. Its 7mm-thick Hyperglide-spline and seven aluminum spacers make the chain-line adjustment hardware part of the package rather than an additional listed component.

The kit is stated to convert a normal HG freehub wheel to single speed, and its CrMo cog has a 7mm-thick Hyperglide-spline. The included alloy lock ring secures the assembly, while seven spacers—two 10mm, one 5mm and four 3mm—offer several ways to position the cog for chain line. The fixed listed 13T size keeps the choice straightforward but gives less gearing flexibility than kits with multiple cog options.

Skip it if you want several gearing options; JFOYH’s 15T/16T/18T kit lists three cog sizes for different riding preferences.

This suits riders converting a normal HG freehub wheel who want the supplied 13T cog and multiple spacer thicknesses for chain-line tuning. Its single listed cog size is the key boundary for gearing choice.

#4 · Best Tensioner Bundle

4. PeakRider Tensioner Bundle

Best for: Quiet Urban Commuting.

Why it ranks #4: Pairs a 15T, 16T, or 18T cog with an adjustable dual-pulley chain tensioner, useful when the frame needs chain take-up.

A CNC double-pulley tensioner with dual-spring guidance is the defining feature of PeakRider’s bundle, intended to reduce chain slap and vibration for quieter riding. The kit pairs it with a 16T cog option, a stated balance for everyday commuting and urban use.

The cog is CNC-machined 7075 aluminum and has a reinforced 9mm base, which the listing says protects Shimano HG freehub splines. Its 66g listed weight keeps the cog light, while the included 140g double-pulley tensioner provides guided chain management and dual-spring support. The 15T, 16T and 18T options let riders choose among listed cog sizes; compatibility is specified for Shimano HG hubs.

Skip it if you ride an XD/XDR freehub; the Wheels Manufacturing SOLO-XD kit is listed for XD/XDR bodies.

This bundle suits an urban rider seeking a single-speed conversion with included chain tensioning and a 16T everyday gearing option. Its stated hub fit is Shimano HG, so riders with another freehub type need a different interface.

#5

5. Wheels Manufacturing 16T Set

• Weight: 2.4 oz
• Warranty Description: Limited Warranty

Best for: Angled Spacer Chain-Line Tuning.

Why it ranks #5: Includes a 16T, 3/32-inch cog and multiple spacers for Shimano freehub bodies, with a stated exception for deep-spline 10-speed bodies.

Angled spacers distinguish the Wheels Manufacturing one-speed set, giving Shimano freehub users a specific chain-line adjustment option alongside a 16T, 3/32-inch cog. The listed spacer assortment includes shims as well, useful when the cog position needs more precise tuning.

The kit is listed for Shimano freehub bodies except deep-spline 10-speed versions. Its 16T cog is specified for 9-speed use, and the angled spacers provide another way to arrange the stack while the 1mm shims allow small positioning changes. The included lock ring completes the conversion hardware. This makes the set particularly relevant to a Shimano-body setup, but the stated deep-spline exclusion narrows compatibility.

Skip it if you have a deep-spline 10-speed Shimano body; Bibike’s kit is listed for Shimano or SRAM 8–11-speed HG bodies.

Choose this set for a compatible Shimano freehub conversion where a 16T cog, angled spacers and fine shims suit your chain-line setup. Its stated exclusion of deep-spline 10-speed bodies is decisive.

#6

6. CooMeng Single Speed Kit

• Weight: 0.1 kg
• Material: Aluminum, Nylon, Steel
• Warranty Description: 12 Mounth

Best for: Dirt Jump Chain Retention.

Why it ranks #6: Offers 15T, 16T, and 18T aluminum cogs with a 9mm base, spacers, and a lock ring for conversions using a compatible freehub.

Extra-tall teeth paired with a narrow-wide tooth profile are the CooMeng kit’s key distinction, supporting chain retention even when a chain tensioner is used. Its 9mm-thick base is also specified to spread stress across the freehub, a relevant combination for dirt-jump or BMX conversions.

The one-piece 7075 aluminum cog has a 9mm base that the listing says distributes stress across the freehub under heavy loads, while the extra-tall teeth address chain retention with a tensioner. A dedicated tooth shape and stated roundness support smooth engagement and reduced wear. The kit includes 12mm, 7mm and 2mm spacers plus a lock ring, providing components to set the cog position during installation.

Skip it if you want an explicitly listed Shimano HG fit and a choice of cog sizes; PeakRider’s 15T/16T/18T bundle specifies Shimano HG hubs.

Consider this for dirt-jump or BMX use where a tensioner and chain retention matter, and where a 16T cog suits your gearing. The listing emphasizes the cog and spacer set, so factor in your installation needs.

#7

7. JFOYH Single Speed Kit

• Material: 7075 Aluminum
• Warranty Description: 12-Month Limited Warranty

Best for: Hard-Riding 7075 Cog.

Why it ranks #7: Its 7075 aluminum cog has a reinforced 9mm base and 15T, 16T, or 18T options; compatibility is specified for Shimano HG freehubs.

JFOYH’s reinforced 9mm base is specified to distribute stress across the freehub under hard riding, giving this kit a concrete focus for BMX and dirt-jump conversions. Extra-tall teeth are intended to improve chain retention, including when a tensioner is part of the setup.

The 7075 aluminum cog combines its thick base with a precise single-speed tooth profile and stated roundness, features the listing connects with smooth engagement and reduced wear. Those details suit riders prioritizing a durable cog interface and consistent chain contact. Available sizes are 15T, 16T and 18T: the supplied guidance associates 15T with higher speed, 16T with balance, and 18T with more torque and easier pedaling.

Skip it if you need an XD/XDR interface; Wheels Manufacturing’s SOLO-XD kit is specified for XD/XDR freehub bodies.

This is a fit for BMX and dirt-jump riders choosing among three cog sizes and prioritizing the listed thick base and tall teeth. Confirm the Shimano HG interface matches your wheel before committing.

#8 · Best XD/XDR Fit

8. Wheels Mfg Solo-XD Kit

• Weight: 7.2 oz
• Warranty Description: Limited Warranty

Best for: XD/XDR Technical-Terrain Setup.

Why it ranks #8: Designed for XD/XDR freehub bodies rather than the more common HG setup; its 7075 aluminum parts and narrow-wide teeth suit that specific fit.

Compatibility with XD/XDR freehub bodies sets the Wheels Manufacturing SOLO-XD apart for riders using that interface. Its narrow-wide tooth pattern is specified to support chain retention and smooth power transfer, a useful pairing for the aggressive riding and technical terrain named in the listing.

The 7075 aluminum carrier and cogs are described as lightweight and durable, while the narrow-wide tooth pattern is intended to maintain chain retention during riding on technical terrain. The kit is specified for 9–12-speed chains, including SRAM Eagle, SRAM T-Type and KMC, offering a broad listed chain range. Its 18T size gives this version a defined gearing choice; the essential compatibility boundary is the XD/XDR freehub body.

Skip it if you have a Shimano HG wheel; PeakRider’s 15T/16T/18T conversion bundle is specified for Shimano HG hubs.

This kit fits riders with an XD/XDR wheel seeking a single-speed setup for technical terrain and a narrow-wide retention profile. Its listed 18T gearing and XD/XDR interface are the main fit boundaries.
