How to choose a road bike

It may be that you're already familiar with the intricacies of a road bike and you know exactly what you're looking for. But if not, or if you want a refresher, this section will quickly recap the key points to keep in mind when choosing a road bike.

If you're buying your first road bike this information will help you make an informed choice and could make the difference between buying a race bike you like and one you love.  

• Aim light: Whether you're looking to ride a sportive or even race, a light road bike will be of benefit, accelerating faster and quicker at cruising. Aluminium or carbon fibre bike frames are both great choices.

• Choose versatility: at this price point it may be that you're thinking about using your bike competitively, but still want something that can function as a commuter, or in more relaxed settings. Choosing a versatile aluminium frame lets you switch between uses based on your needs: mudguard and pannier eyelets, for example, let you add or remove these components as and when you need them.

• Consider the components: as you move upward through price points, you gain access to increasingly high-quality components such as disc brakes. Look at the individual components - cassettes, derailleurs, gear levers etc - and don't be afraid to research the specifications of each.

• Don't rush it: take your time when deciding which bike to buy, and feel free to ask questions. Taking a considered approach to the decision will help you to find a bike that really aligns with your needs, and represents a solid investment rather than an impulse buy.

Road Bike FAQs

Are mechanical disc brakes no longer used in road cycling?

Road bikes have largely transitioned away from mechanical disc brakes due to the superior performance of hydraulic systems, which offer better modulation and increased stopping power. Additionally, hydraulic disc brakes provide more consistent performance in all weather conditions, a crucial factor for modern road cycling.

Why do modern road bikes rarely use rim brakes?

Most bikes from the premium brands found at Sigma Sports have stepped away from rim brakes to disc brakes due to their superior and consistent stopping power, especially in wet conditions. Additionally, unlike rim brake bikes, disc brakes allow for wider tyre clearance, which improves ride comfort and versatility.

Do budget road bikes have a more relaxed geometry?

Yes, generally cheaper road bikes often feature a more relaxed geometry, prioritising rider comfort for longer, less aggressive rides. This contrasts with expensive performance models, which typically have an aggressive geometry designed for optimal power transfer and aerodynamic positioning. If you are looking for aero gains frame material is probably also another consideration.

Do road bikes still come with rack and mudguard mounts?

Mudguard and rack mounts are often found on road bikes at this price point. Bikes at this price are often not used as a race bike but instead by those taking on longer rides, dirt roads and commutes. An all road bike such as the Trek Domane offers ride quality, premium aluminium alloy and rack mounts to ensure it can be used as a gravel bike as well as on the road, which makes it one of the best cheap road bikes on the market.

What qualities should I look for in an endurance bike?

When looking for an endurance bike, look for comfort-focused geometry which will give you a more comfortable ride and enhance ride quality over longer distances. Look for a bike with a taller head tube and a shorter reach, promoting a more upright and relaxed riding position.

Many budget road bikes now come with additional features like internal cable routing, wider tyre clearance, flexible frame materials, and vibration-absorbing components.
