Read our Expert Review
Key Specifications
- Frame: Specialized E5 Premium aluminum alloy
- Groupset: Shimano Claris
- Wheelset: Axis Sport aluminum alloy
- Claimed Weight: 10.0kg / 22lbs
Reasons to Choose the Specialized Allez
- Superior Ride Quality: Offers a ride that is both comfortable and engaging, making it enjoyable for various types of road riding.
- Easy Setup: Designed for straightforward assembly and maintenance, beneficial for new cyclists.
- Versatility: Capable of handling different terrains beyond smooth roads, increasing its usability.

Considerations Before Choosing
- Price Point: While competitive, it’s positioned at the higher end of the entry-level price range.
- Mechanical Disc Brake Performance: The mechanical disc brakes, while an upgrade from rim brakes, don’t offer the same level of power and modulation as hydraulic systems.
Specialized’s 2023 Allez update marks a significant step forward, replacing rim brakes with disc brakes, which in turn has allowed for greater tire clearance, now accommodating up to 35mm tires, or 32mm with fenders. This enhancement dramatically increases ride comfort and opens up the Allez to light gravel paths, expanding its usability beyond just smooth pavement.
During our testing, we appreciated this newfound versatility, noting its suitability for light touring or commuting thanks to the inclusion of rack mounts. Crucially, the Allez retains its sporty essence; with a lowered stem, it proved to be a quick and responsive companion.
The base model features Shimano Claris 8-speed shifting and mechanical disc brakes. The Claris groupset has noticeable gaps between gear ratios on the 11-32t cassette, and as expected, the mechanical disc brakes lack the robust stopping power of hydraulic brakes.
The current Allez range includes two main models (plus the performance-oriented Allez Sprint). The upgraded Allez Sport offers 10-speed shifting and hydraulic disc brakes but comes with a significant price increase for what is otherwise a similar overall package.
Upgrading the wheelset would notably improve the bike’s performance, but overall, the Specialized Allez presents a solid package for its price, making it a strong contender among the best budget road bikes we have evaluated.

Choosing the Right Road Bike: A Comprehensive Guide
Race Geometry vs. Endurance Geometry: Understanding the Differences
When selecting the best road bike, a critical decision is determining your primary cycling goals. Are you focused on speed and racing, or do you prefer a more comfortable bike for leisurely rides and long-distance cycling?
Geometry plays a pivotal role here. A race bike typically positions you in a more aggressive, bent-over posture, lowering your head and shoulders closer to the handlebars. This setup is ideal for reducing wind resistance and maximizing speed but can be less comfortable, especially for beginners or longer rides.
Conversely, endurance or sportive bikes are designed for a more upright riding position, with handlebars positioned higher and closer to the saddle. This geometry prioritizes comfort for extended rides but might slightly reduce aerodynamic efficiency.
If you frequently ride on hilly roads or plan to tackle mountainous terrains like the Alps, a lightweight bike is highly beneficial. However, if your rides are primarily on flatter terrain where speed is key, aerodynamics become more important. For racing, the stiffer and more responsive handling of a race bike is preferable to the more stable handling of an endurance bike.
Increasingly, bikes are being designed to handle both paved and unpaved surfaces. A gravel bike offers wider tires and lower gear ratios for off-road capabilities. Many modern endurance or all-road bikes also provide ample tire clearance and a wide gear range, allowing for exploration of diverse routes beyond smooth tarmac.
Budgeting for Your Road Bike: Initial Costs and Beyond
Consider not just the initial purchase price of a road bike, but also the ongoing expenses such as replacing worn parts, routine servicing, and potential upgrades. The cost difference between basic mechanical components and high-end electronic groupsets is significant.
Component specifications vary widely among manufacturers. Direct-to-consumer brands like Canyon and Ribble, and in-house brands such as Vitus (at Wiggle) or Boardman (at Halfords) often offer more competitive pricing. However, to provide a general guideline, here are typical specifications at different investment levels. Note that these are broad ranges, and variations exist within each category.

Frame Materials: Aluminum, Carbon, Titanium, and Steel
A significant differentiator between road bikes is the frame material. Bikes under $/£1000 typically use aluminum alloy, known for being strong and lightweight.
More expensive bikes often feature carbon fiber frames. Carbon fibers are embedded in a resin, and the type of fiber and lay-up affect the bike’s ride quality and weight. High-modulus carbon reduces weight without sacrificing strength.
Titanium is another premium material, prized for its light weight, strength, and resistance to rust and fatigue. Steel tubing, the traditional frame material, is still used for its robustness and unique ride feel, though it is heavier than other options.
Also, consider the fork material. Many bikes have all-carbon forks or carbon blades with an alloy steerer, which enhance comfort by absorbing road vibrations. Some entry-level bikes may use alloy or steel forks.
Bike Sizing: Ensuring the Perfect Fit
Selecting the right size bike is crucial for comfort and efficiency. Most bikes come in various sizes, and manufacturers provide height ranges for each size.
When straddling the bike, you should comfortably place both feet on the ground with clearance between the top tube and your body. Frame dimensions like reach and stack offer more detailed fit information. Stack height indicates the vertical distance from the bottom bracket to the top of the head tube, influencing the uprightness of your riding position. Reach is the horizontal distance, affecting how stretched out you feel. Race bikes typically have lower stack heights than endurance models.
For optimal bike setup and injury prevention, a professional bike fit is highly recommended. It ensures your saddle and handlebars are positioned for efficient and comfortable riding.

Aero Road Bikes: Do You Need Aerodynamics?
Bike manufacturers heavily promote aerodynamic advantages, especially on higher-end models, citing wind tunnel tests and time savings. While early aero bikes were heavier, modern aero bikes can be as light as non-aero bikes.
However, approximately 80% of wind resistance comes from the rider, not the bike. Aerodynamic gains are most significant at speeds around 45kph/28mph. At lower speeds, the benefits diminish considerably.
Gears: How Many Speeds Do You Need?
Gearing is a key consideration after frame material. High-end road bikes often feature 12-speed cassettes, providing 24 theoretical gears when paired with a double chainring, though some gear ratios may overlap.
More affordable road bikes usually have 8-speed to 10-speed cassettes, also typically with double chainrings. Shimano is the most common groupset brand, with SRAM and Campagnolo as other major options. Shimano’s top groupsets (Dura-Ace, Ultegra, 105) are 12-speed, while lower-priced bikes may have 10-speed Tiagra, 9-speed Sora, or 8-speed Claris. SRAM and Campagnolo also offer 12-speed top-tier road bike groupsets. Electronic shifting is available from all three brands, replacing mechanical cables.

Gear Ratios: Choosing the Right Setup
When selecting a road bike, consider the gear ratios. Race bikes might have a traditional setup with a 53/39 tooth chainset and an 11-30 tooth cassette.
Endurance and sportive bikes often use a compact 50/34 chainset and a cassette with up to 36 teeth, providing lower gears for easier climbing and higher cadence. However, this can result in larger gaps between gear ratios.
SRAM offers eTap AXS groupsets with chainsets like 48/35, 46/33, and 43/30t, paired with 10-tooth start cassettes, providing similar high-end ratios to traditional setups but with more low-end range for climbing and less frequent chainring shifts.
Electronic vs. Mechanical Shifting: Is Electronic Worth It?
While mechanical groupsets are still available, electronic shifting has become increasingly popular. Systems like Shimano Di2, Campagnolo Wireless, and SRAM eTap AXS offer 12-speed options and use motors for gear changes, rather than cables.
Mechanical systems are generally cheaper, lighter, and easier to repair. Electronic systems offer consistent, reliable shifting with the push of a button. They can be personalized via apps for features like seamless multi-gear shifts. However, they are more expensive, and require battery charging.
Electronic shifting components on a high-end road bike
Electronic shifting is becoming a standard feature on higher-specification road bikes, offering enhanced performance and customization.
Disc Brakes vs. Rim Brakes: Which is Better?
Disc brakes have become dominant on road bikes, with most new models being disc brake only. Rim brake bikes are still available, mainly at the high and low ends of the price spectrum.
Disc brakes provide more consistent braking in all weather, better modulation, and greater stopping power. They are heavier than rim brakes, but frame technology has reduced this weight penalty. Most disc brake bikes use hydraulic calipers, though mechanical disc brakes are found on some cheaper models. Disc brakes are increasingly common even at lower price points.
Hydraulic disc brakes on a road bike
Disc brakes are now standard on most new road bikes, offering superior stopping power and reliability in all conditions.
Wheels: Carbon vs. Alloy
Road bike wheels are typically 700c, with 650b size on some smaller frames. Both carbon and alloy rims are available. Carbon rims are lighter, often deeper for aerodynamics, and can be shaped more aerodynamically.
Alloy rims are more affordable and common on complete bikes. They are generally heavier, though lightweight alloy options exist. Wheels are often a component where manufacturers economize, so upgrading to better wheels can significantly improve bike performance.

Wider tires, combined with tubeless setups and carbon wheels, enhance comfort and performance on modern road bikes.
Tire Width: Finding the Right Balance
Road bike tire widths have increased over time. 23mm tires were once common; now, even race bikes accommodate 28mm to 32mm tires, while endurance bikes allow even wider options. Wider tires allow for lower tire pressure for more comfort and better grip. Wider tires can be as fast as or faster than narrower tires.
Tubeless-ready wheels and tires are increasingly common, allowing sealant use and eliminating inner tubes to reduce punctures, increase grip, and improve ride comfort and speed.
