Factors to Consider When Buying

Purpose/Type of Riding
Before diving into wheel specifics, introspect on the kind of rider you are. Your choice of wheel should reflect your predominant riding style.
- Recreational: For those who ride for pleasure, prioritize comfort and durability. Consider wider rims and tires to absorb road imperfections.
- Racing: Seek lightweight and aerodynamic wheels that offer quick acceleration and maximum power transfer.
- Long-distance/Touring: Durability is essential. Look for robust wheels that can handle the added weight of luggage and prolonged usage.
Discipline-Specific Considerations Your choice of road cycling discipline can significantly influence the wheel you’ll need.
- Endurance Riding:
  - Comfort and Vibration Damping: Wider rims and tires can offer a smoother, fatigue-free ride. Some carbon wheels also provide added vibration damping.
  - Durability: Opt for wheels built for resilience, capable of handling both long distances and varied road conditions.
  - Versatility: Look for wheels that can handle mixed terrains, especially if your endurance rides sometimes venture off the beaten tarmac.
- Criterium Racing:
  - Acceleration: Crits involve many quick bursts of speed. Lightweight wheels respond faster, offering that needed edge.
  - Handling and Stability: Tight corners are a crit staple. Stiffer wheels ensure better control in such scenarios.
  - Braking Performance: With rapid decelerations, effective braking becomes vital. Consider the brake compatibility and the braking surface material.
- Time Trials/Triathlon:
  - Aerodynamics: Aerodynamic efficiency is paramount. Deep-section rims, often 50mm or more, reduce drag, enhancing speed.
  - Stiffness for Power Transfer: Consistently high speeds mean you’ll want wheels that transfer power efficiently without energy loss.
  - Straight-line Stability: Time trials aren’t about nimble turns but maintaining a straight line at high speeds. Ensure your wheels offer stability, especially in crosswinds.
- Climbing:
  - Weight: Every gram counts when fighting gravity. Seek ultra-lightweight wheels.
  - Stiffness: You want a wheel that efficiently converts your effort into forward motion, especially on steeper gradients.
  - Braking Performance: What goes up must come down. Excellent braking performance is crucial for the descents that follow tough climbs.
Weight and Stiffness
Balance is key. While you might be tempted by ultra-lightweight wheels, remember that sturdiness shouldn’t be sacrificed. A stiffer wheel might feel less compliant on rough roads, but it can offer better power transfer and responsiveness, particularly during sprints or aggressive cornering.
Aerodynamics
The rim’s depth, shape, and even the spoke count and design can influence how air flows over a wheel, affecting speed and stability. While deeper rims are more aerodynamic, they can be challenging in crosswinds and might weigh more.
Material
- Aluminum: Typically more affordable and durable, making them suitable for everyday use. They might weigh more and lack the vibration-damping qualities of carbon.
- Carbon: Offers weight savings, better aerodynamics, and enhanced vibration damping. However, they come at a premium and might be less resilient in crashes.
Braking Performance
The choice between rim and disc brakes will influence the wheels you can buy. Ensure the wheelset is compatible with your bike’s braking system. Consider the conditions you often ride in; for instance, disc brakes perform better in wet conditions.
Budget and Price Range
While it’s tempting to buy the latest, high-end wheelsets, it’s essential to gauge what you’re getting for the price. More expensive doesn’t always mean better for your specific needs. Define a budget, understand what features matter most to you, and find a wheel that offers the best value within that range.

Hub Considerations

The hub is the heart of a wheel, and its design and components play a crucial role in the wheel’s performance.

Bearings: Two common types are found in hubs:
- Sealed Cartridge Bearings: These are self-contained units that are replaceable and easy to maintain. They tend to keep out dirt and moisture effectively, leading to longer life.
- Cup and Cone Bearings: More traditional and adjustable, these require regular maintenance and are found on some high-end and many budget wheelsets.
Engagement Mechanism: This refers to how the wheel engages (or catches) when you pedal. A hub with quick engagement means less lag when you start pedaling, which can be especially beneficial in situations requiring frequent stop-starts or bursts of speed.
Flange Design: The flange is the part of the hub where the spokes attach. Its design affects the angle and tension of the spokes, influencing wheel strength and responsiveness.

Spoke Configuration

Spokes contribute significantly to a wheel’s strength, weight, and aerodynamics.

Number of Spokes: A higher spoke count often translates to a stronger, albeit slightly heavier, wheel. Conversely, a wheel with fewer spokes might be lighter and more aerodynamic but less durable.
Spoke Patterns:
- Radial Lacing: Spokes run straight from the hub to the rim. This configuration can be lighter but is typically used only on the front wheel.
- Cross-Laced Patterns: Spokes cross each other, which can add strength, making them suitable for rear wheels or for riders who need more robust wheels.
Spoke Materials: While stainless steel is standard and offers strength and durability, bladed spokes (which are flattened) can improve aerodynamics. Carbon spokes are lighter but come at a premium.

Wheelset Extras and Maintenance

Caring for your wheels can significantly extend their lifespan.

Axle Types:
- Quick Release: A mechanism that allows for easy wheel removal without tools. Suitable for many road bikes.
- Thru-Axles: Provides a sturdier wheel-to-frame connection, improving stiffness and handling. Increasingly standard on newer bikes.
Maintenance: Regularly inspect hubs, spokes, and rims for signs of wear or damage. Clean and, if necessary, grease bearings periodically. True your wheels if they wobble or are misaligned.
Tubeless Setups: If going tubeless, ensure the rim is sealed correctly with rim tape to maintain an airtight environment.

Recommendations & Top Picks

There’s no one-size-fits-all when it comes to wheelsets.

Local Bike Shops: Engage with professionals who can provide tailored advice based on your specific needs, riding style, and budget.
Research: Look into reputable brands and the latest innovations. While brand legacy matters, newer brands might offer innovative designs at competitive prices.

Is a 29 inch wheel the same as 700c?

Yes and no. While both 29-inch wheels and 700c wheels have a similar bead seat diameter (the place on the wheel where the tire bead sits) of approximately 622mm, they are traditionally used for different types of bikes and have different typical widths. Here’s a breakdown:

700c Wheels:
- Usage: Traditionally used for road bikes, though now they’re also found on many hybrid and gravel bikes.
- Width: Generally, they are designed for narrower tires (though gravel and some hybrid bikes can accommodate much wider tires on a 700c rim).
- Naming: “700c” comes from an old French tire sizing system.
29-inch Wheels:
- Usage: Used for mountain bikes.
- Width: Designed for wider tires, typical of mountain bikes. They offer more cushioning, grip, and shock absorption on rough terrains.
- Naming: “29-inch” refers to the approximate diameter of the tire when mounted and inflated on the rim. This measurement is somewhat of a generalization, as actual tire diameters can vary based on tire model and tread pattern.

So, while you could technically mount a narrow road tire on a 29-inch mountain bike rim or a wide mountain bike tire on a 700c road rim (assuming the rim width is appropriate), the traditional uses and associated widths of these wheels differ. Always ensure that the tire width is appropriate for the rim width and the intended use.
