1. Miche Primato Flip Flop Hub: Best Overall
The Miche Primato Flip Flop Hub stands out in our research for its consistent quality and smooth performance. Owner feedback highlights the sealed cartridge bearings as a major upgrade over loose ball designs, providing long service life with minimal maintenance. The hub body is machined from 6061 aluminum, while the axle is heat-treated steel, meeting common strength standards for track use. In our evaluation of owner reports, the Primato rarely develops play or roughness even after thousands of miles.
However, the axle nuts require careful installation with a torque wrench to prevent loosening. Riders who frequently switch gearing may find the single-sided lockring thread inconvenient. This hub is best for riders who want a dependable, low-friction hub and don’t need multi-speed capability. Skip it if you prefer a budget option or need a hub with both threaded sides for easier cog swaps.
- Smooth sealed cartridge bearings reduce maintenance
- Machined aluminum body with steel axle for strength
- Compatible with both fixed and freewheel cogs
Pros: Reliable bearing system with low drag; Easy cog swap with standard lockring threads
Cons: Axle nuts can loosen if not torqued properly
2. Origin8 Track Hub Flip Flop: Best Value
The Origin8 Track Hub Flip Flop is a budget-friendly choice that still delivers acceptable performance for casual riding and commuting. Based on owner feedback, the hub runs smoothly out of the box, but the loose ball bearing system demands regular maintenance to prevent play. The double-sided threading is a thoughtful feature that lets you run a fixed cog on one side and a freewheel on the other without additional adapters. In our comparison, it offers the best value for riders who don’t need premium sealed bearings.
Durability is adequate for light use, but some owners report the bearings wearing faster under heavy loads or wet conditions. This hub is ideal for fixed gear beginners or those on a tight budget. Skip it if you ride in harsh weather or need a hub that can withstand aggressive track riding without constant adjustment.
- Affordable price point with solid build quality
- Loose ball bearing design for easy servicing
- Double-sided threading for fixed/freewheel on both sides
Pros: Very cost effective for budget builds; Double-sided threading simplifies cog swaps
Cons: Loose ball bearings require periodic adjustment
3. All-City Flip Flop Hub: Premium Pick
The All-City Flip Flop Hub is a premium option that excels in durability and smoothness. Our research into owner reviews reveals near-universal praise for the sealed cartridge bearings, which stay buttery smooth even after extensive use. The heat-treated chromoly axle meets or exceeds typical strength standards for track hubs, and the anodized finish resists corrosion. In our evaluation, this hub offers the best long-term reliability among the models we compared.
However, the premium build comes at a higher cost, making it less accessible for budget builds. Some users note that the hub is slightly heavier than minimalist track hubs. This hub is best for serious fixed gear riders who want a set-and-forget component. Skip it if you are building a low-cost commuter or if weight is your top priority.
- Premium sealed bearings with excellent longevity
- Heat-treated chromoly axle for high strength
- Machined hub shell with anodized finish
Pros: Exceptional build quality and bearing smoothness; Axle is very resistant to bending
Cons: Higher price point than many alternatives
4. Surly Ultra New Hub: Most Durable
The Surly Ultra New Hub is built like a tank, prioritizing strength over weight savings. In our evaluation of owner feedback, this hub is often chosen for touring or heavy-duty use where reliability is paramount. The sealed cartridge bearings are housed in a robust shell with thick flanges that resist bending. The hub meets Surly’s own high durability standards, and many owners report it outlasting multiple bikes.
However, the hub is noticeably heavy, and it requires Surly-specific cogs that are less common and more expensive. The flip flop functionality is also limited because the non-drive side uses a standard thread. This hub is ideal for riders who prioritize toughness and plan to keep the bike for years. Skip it if you want a lightweight track hub or prefer standard cog compatibility.
- Overbuilt design with thick flanges and axle
- Sealed bearings with excellent weather resistance
- Compatible with Surly's unique cog system
Pros: Extremely tough, survives crashes and abuse; Bearings are well protected from dirt
Cons: Heavier than most flip flop hubs; Cog compatibility limited to Surly cogs
5. Velocity Flip Flop Hub: Lightweight Choice
The Velocity Flip Flop Hub is a lightweight option that appeals to weight-conscious fixed gear riders. Its sealed cartridge bearings provide low rolling resistance, and the hub is available in several drillings and anodized colors. Owner reviews generally praise the hub’s initial smoothness and aesthetic options. In our comparison, it is one of the lightest hubs we evaluated.
However, durability is a concern. Some owners report flange cracks when using high spoke tension or after hard impacts. The hub is not recommended for heavy riders or aggressive track use. This hub is best for light riders or those building a weight-weenie fixed gear. Skip it if you need a hub that can withstand rough roads or heavy loads.
- Low weight at approximately 280g
- Smooth sealed cartridge bearings
- Available in multiple hole counts and colors
Pros: Very light for a flip flop hub; Bearing smoothness is good out of the box
Cons: Flanges can crack under extreme tension
6. Formula Flip Flop Hub: Budget Pick
The Formula Flip Flop Hub is the most budget-friendly option in our comparison. Owner feedback indicates it works adequately for casual riding, but the loose ball bearings often require adjustment within a few months. The hub meets basic industry standards for track use, but the axle and cones are less robust than higher-priced models. In our evaluation, it offers the lowest cost of entry for fixed gear conversion.
However, durability is limited. Many owners report the hub developing roughness or play after a few hundred miles, especially in wet conditions. This hub is best for a low-mileage commuter or a first build where cost is the primary concern. Skip it if you plan to ride daily or expect long-term reliability without frequent maintenance.
- Very low price point for entry-level builds
- Loose ball design allows easy servicing
- Standard threading works with most cogs
Pros: Extremely affordable; Simple and serviceable design
Cons: Bearings can develop play quickly
7. Phil Wood Flip Flop Hub: Ultimate Quality
The Phil Wood Flip Flop Hub represents the pinnacle of hub quality. Our research shows that owner reviews are overwhelmingly positive, citing incredible bearing smoothness that lasts for years. The hub is made in the USA with precision machining, and the sealed cartridge bearings are among the best in the industry. Phil Wood backs the hub with a lifetime warranty, reflecting their confidence in its durability.
The main drawback is the price, which is significantly higher than any other hub we evaluated. Additionally, the hub is relatively heavy due to its robust construction. This hub is best for riders who want the absolute best and are willing to pay for it, such as serious track racers or collectors. Skip it if you are on a tight budget or if weight is a primary concern.
- Handmade in USA with premium materials
- Smooth, long-lasting sealed bearings
- Lifetime warranty on bearings and body
Pros: Exceptional smoothness and durability; Lifetime warranty adds peace of mind
Cons: Very high price, often over budget
Frequently Asked Questions
What is a flip flop hub and how does it work?
A flip flop hub has two threaded sides: one for a fixed cog and one for a freewheel. You can flip the wheel to switch between fixed gear and freewheel modes without changing the hub. It is common on track bikes and fixed gear conversions.
What is the difference between sealed cartridge bearings and loose ball bearings?
Sealed cartridge bearings are pre-assembled units that are easier to maintain and more resistant to dirt and water. Loose ball bearings are adjustable and can be serviced, but they require more frequent maintenance and are less durable in harsh conditions.
What axle spacing do I need for a flip flop hub?
Most track and fixed gear hubs use 120mm over locknut distance (OLD). Some modern frames use 130mm or 135mm, but 120mm is standard for track hubs. Check your frame’s dropout spacing before purchasing.
Can I use a flip flop hub on a road bike frame?
Yes, if the frame has horizontal dropouts and 120mm spacing. Many road frames have vertical dropouts or wider spacing, which may require adapters or a different hub. Always verify compatibility.
Do flip flop hubs work with both fixed and freewheel cogs?
Yes, that is the purpose. One side is threaded for a fixed cog (with lockring), and the other side is threaded for a freewheel. Make sure the threads are compatible with your chosen cog or freewheel.
Our Verdict
After researching specifications and owner feedback, the Miche Primato Flip Flop Hub earns our top recommendation for its balanced performance, durability, and value. For those seeking premium quality, the Phil Wood Flip Flop Hub is an unrivaled choice, though at a higher price. Consider your budget and riding needs when choosing.
