If you're tired of being locked into a single riding style, swapping your stock hoops for a flip flop wheelset 700c is easily one of the smartest moves you can make for your bike. It's basically the "choose your own adventure" of the cycling world, giving you the freedom to switch between a fixed-gear setup and a standard single-speed freewheel without needing a whole second bike taking up space in your hallway.
Most people who get into the fixie scene eventually realize that while riding fixed is an absolute blast for connectivity and control, sometimes your knees just need a break. That's where the magic of the flip-flop hub comes in. You get two different vibes on one wheel.
What exactly is a flip flop hub?
At first glance, a flip-flop wheel looks just like any other rear bicycle wheel, but the secret is in the hub. Instead of having threads on just one side for a single cog, it has threads on both sides. One side is designed for a fixed cog—usually with a stepped thread for a lockring to keep things from spinning off when you backpedal—and the other side is threaded for a standard freewheel.
The "700c" part is just the standard size for road and track bikes. It's the sweet spot for speed and efficiency. When you combine that standard sizing with a flip-flop hub, you're getting a wheelset that fits almost any modern track or urban frame.
The beauty is in the simplicity. If you're feeling like a hardcore track racer on Monday, you run the fixed side. If you have a hilly commute on Tuesday or just want to coast down a long descent without your legs spinning like a blender, you literally take the wheel off, flip it around, and bolt it back in. It takes about two minutes once you get the hang of it.
Why the 700c size is the gold standard
You might wonder why we don't see more variation in wheel sizes for urban riding, but the 700c diameter has stuck around for a reason. It's large enough to roll over potholes and road debris with relative ease, yet light enough to accelerate quickly from a stoplight. When you're shopping for a flip flop wheelset 700c, you're tapping into the widest selection of tires on the planet.
Whether you want 23mm "pizza cutter" tires for maximum speed or 32mm supple tires for a cushier ride over cobblestones, a 700c rim will likely accommodate you. Just make sure your frame has the clearance for those wider tires before you buy them. Most modern "fixie" frames are designed around this wheel size, making it a plug-and-play upgrade.
Choosing between fixed and freewheel
Let's talk about the two personalities of this wheelset.
Riding Fixed: This is where the rear cog is directly threaded onto the hub. If the wheel moves, your pedals move. It gives you a direct connection to the road that's hard to describe until you've felt it. You can control your speed just by resisting the rotation of the pedals. It's a great workout and makes you a much more "aware" rider.
Riding Freewheel: This is the "relaxed" side. The freewheel allows the wheel to spin independently of the pedals. You can coast down hills, stand up on the pedals to stretch your legs, and generally enjoy a more traditional bicycle feel.
Having both options on a single flip flop wheelset 700c means you don't have to commit. It's perfect for beginners who are intimidated by fixed-gear riding but want to try it out. You can start on the freewheel side, get comfortable with the bike, and then flip it over once you're feeling brave.
What to look for when you're shopping
Not all wheelsets are created equal. If you're browsing for a new set, there are a few technical specs you should keep an eye on to ensure you're getting something that'll last.
Rim Depth and Aesthetics
You'll see everything from shallow, box-section rims to deep-dish "v-section" rims. Deep rims (often 40mm or more) look incredibly cool and are very stiff, but they can be a bit heavy and can catch the wind like a sail. If you live in a particularly windy city, a mid-depth rim (around 25-30mm) is usually the best "do-it-all" choice.
Sealed Bearings vs. Loose Ball
If you can swing it, go for a hub with sealed cartridge bearings. They require way less maintenance and are much better at keeping out the rain and grit of city streets. Loose ball bearings are fine and easy to service yourself, but they tend to need more frequent attention to keep them spinning smoothly.
Bolt-on vs. Quick Release
For a flip flop wheelset 700c, you're almost always looking at a bolt-on axle. Since you're likely using this on a frame with horizontal dropouts, you need the security of nuts to keep the wheel from slipping forward under the torque of your pedaling. Plus, it's a tiny bit more theft-resistant than a quick-release lever.
Installation and the chain line
One thing that trips people up when they first get a flip-flop wheelset is the chain line. For a single-speed or fixed-gear bike to run silently and efficiently, the chain needs to be as straight as possible between the front chainring and the rear cog.
Most flip flop wheelset 700c options are spaced at 120mm, which is the standard for track-style frames. If you're trying to put these on an old converted road bike frame (which might be 126mm or 130mm), you might need some spacers to get everything lined up. Don't ignore this! A crooked chain line leads to extra wear on your drivetrain and that annoying "clicking" sound every time you pedal.
Also, don't forget the brakes. If you're planning on using the freewheel side, you must have at least a front brake (preferably both). On the fixed side, you can technically slow down with your legs, but for street riding, a brake is still a literal lifesaver.
Maintenance tips for longevity
To keep your new wheelset spinning for years, a little TLC goes a long way.
- Check your tension: Brand new wheels often "settle" after the first few rides. After a week or two, check the spokes to make sure they're still tight. If the wheel starts to wobble, get it trued at a local shop.
- Grease those threads: Before you screw on your fixed cog or freewheel, apply a bit of anti-seize or grease to the threads. This prevents the metal from "cold welding" together, which would make it impossible to change your gearing later.
- Keep the rims clean: If you're using rim brakes, wipe down the braking surface occasionally. Road grime and brake pad dust can turn into a gritty paste that wears down your aluminum rims faster than necessary.
Is it worth the upgrade?
Honestly, if you're riding a cheap "big box" bike or an old conversion with heavy, unsealed wheels, moving to a decent flip flop wheelset 700c is the most noticeable upgrade you can make. It's not just about the versatility of the hub; it's about reducing rotating mass. Lighter, stiffer wheels make the bike feel snappy, responsive, and just more fun to ride.
Whether you're dodging traffic on a morning commute or hitting the local velodrome for some laps, having that dual-sided hub gives you a level of flexibility that most cyclists envy. It's a simple, elegant solution to the age-old question: "Do I want to go fast, or do I want to be comfortable?" With a flip-flop wheel, the answer is simply "Yes."
