Road Bike Buyers Guide
Road biking is one kind of fun of life, it’s give pleasure in life. When you are riding a bike with your friends that is the most enjoyable moment. This is also one way of exercise and meditation as well. But this is all possible only when you have the right choice of your bike.
Before going to buy a road bike you should know this thing
What Is a Road Bike
Let’s see quick overview of road bike
- A very lightweight frame, wheels, and component
- Smooth, skinny, and narrow wheels and tires
- Dropdown handlebar, though some have a flat handlebar like mountain bike
- Forward and downturned posture.
- No front or rear suspension
Now, let’s see what is the functionality of a road bike
- Intention for fitness, touring and road racing.
- Designed for paved surfaces.
- Allow the rider to go farther and faster than other of bike.
Frame Geometry of Bike
The frame is heart of any bike. All though the road bike model looks like the same to each other meticulous but crucial differences in the frame formation and material being used in the frame.
Road bike with a performance geometry appeal to the aggressive ride. These bikes allow the rider to be more flexible and stretched out for aerodynamics and they are more responsive for piloting. Road bikes feature a tough frame, higher-end component, narrow wheels.
Your first frame choices are aluminum or carbon fiber. By the way, how well designed a frame using material as the material quality itself.
The key feature of aluminum frames are very good at providing smooth riding, and they are generally less expensive than carbon fiber. Most aluminum frame road bike comes with carbon fiber front fork to absorb some road vibration to give good quality of riding.
Carbon fiber is the most coveted frame material for road-bike. By the way, carbon fiber is not equally. There is a huge difference between cheap and expensive frames. The carbon fiber frame is very good at absorbing road vibration and provides more comfortable riding than an aluminum frame. Along with that carbon fiber frame is that it is more flexible which helps to create a complex shape that gives more attractive looks.
Steel was the very popular frame material until the 1980s and is still very good material for a good designer. The main problem with it is its havier than carbon or aluminum, but this is best comfortable.
Titanium can be the best choice if you have a good budget. A titanium frame can be lightweight as aluminum and durable as steel. This feature of titanium makes its perfect material for the bike frame. Corrosion-resistance features make it perfect for the road bikes.
Titanium is an expensive option because it’s difficult to work in it.
But these days it’s less expensive than earlier when it was new material for the bike frame.
Components of Bike
These are referred to all the major components which are attached to the bike frame.
- Drivetrain(crankset, rear cassette, chain, derailleurs, brake levers, gear levers)
- Wheels( rims, hubs, axle, spokes)
- Brakes, handlebar, seat, and Seatpost, pedals
A groupset is a set of matching components from the component manufacturer. A bike model with a groupset has a refined, stylish and compatible appearance compared to a bike containing a diverse classification of components.
The groupset is generally used to shortcut to define the quality of a bike and to compare different bikes. Shimano, SRAM, and Campagnolo are the most popular component supplier of drivetrains. For the entry-level price, Shimano is the most popular. These three manufacturers make combine gear and brake lever, so you can’t change gear. Every manufacturer does this in a different way. Shimano uses the whole brake lever to shift one-way lever behind it for the opposite shift.
Cranksets and Gearing
Discussion on the road bike often turns on gearing. Let’s start with the cranksets. This is the componentry that the pedals turn and that rotates the rear wheel using the chain. A road bike will either have a triple, double or compact cranksets. Chainrings size and number
- A triple crankset has 3 chainrings. It is often paired with 9-speed, 8-speed, and 7-speed cassette on the rear wheel to give it total 27, 24, and 21 gears. This configuration is most common for an entry-level bike and gives a wide range of gears for the rider. The triple chainring is famous for the climb on the mountain or carrying luggage.
- Double and compact cranksets both have 2 chainrings upfront and are paired with a 10-speed cassette in the back for a total of 20-speeds. A compact crankset has smaller chainrings with fewer teeth than double. It gives a lower range of gears. Racing bike rider prefers double chainring.
A compact crankset is a common dispensation on bikes with a sport geometry, as it gives a similar range of gears(from low to high) as a triple but for less weight. A compact or double cranksets also offer batter heel clearance to the crank arm than a triple crankset, which prevents the potential issue of annoying shoe rub on each turn of the pedals.
The range of teeth on the rear cassette also impacts the gearing range of a bike. The higher gear(smallest cassette) will have eleven or twelve teeth. The lowest gear(large cassette) will have twenty-three to twenty-eight teeth or up to thirty-two teeth in the case of the SRAM Apex model. The SRAM Apex drivetrain is a recent modernity that offers a gearing range greater than that of the triple, but it uses a compact crankset. This is achieved by having more teeth on rear cassette than has before been possible on-road bikes, due to change in rear derailleur design. Changing the rear cassette in a relatively inexpensive way to change your bike’s gearing, but there are potential compatibility issues.
Wheels have a major impression on the following
- Weight of the bike
- Acceleration and carries the momentum of the bike
- Aerodynamics and handling power of the wind
Unless you choose a custom-built bike you will not get a choice of wheels while you buy a bike. You can, yet, choose to upgrade to a batter quality wheels once you get a bike. The higher up a bike is in its model range the lighter and faster wheels you will get. 23mm wide tire used to be standard, but nowadays pro cyclists using more comfortable, faster-rolling 25mm and 26mm tires.
Basic models generally come with platform pedals, often with toe cages, while nearly all higher-end models are sold without pedals. It seems odd, for sure. The assumption by bike makers is that a road cyclist is likely to already have a preferred pedal system for use with his or her existing cycling shoes. This logic lets you make the decision instead of requiring the bike shop to exchange perfectly fine pedals for a different brand or model.
If you want to pedal efficiently and be at one with your bike, you should use cycling shoes and clip-in pedals. Pedals come with numbers of popular brands (including Shimano, Look, Time and Speedplay) and a range of models within each brand. A higher price indicates better bearings, lower rubs, and less weight.
Brake is the major part of any bike. Brake is differentiated in two type
- Rim brake
- Disc brake
The main differences between them are how and where brake forces are going to apply.
A rim brake force is applied to the rim or side of the wheels. Rim brake is still lightweight and more aerodynamic. This is traditionally the most popular brake because of simplicity.
The disc brake is borrowed from a car and motorbike. It is proven to provide more finite braking control and consistent power. In the new bike, it is very popular.
Name of disc brake because of putting a steel disc rotor on the hub of the wheel. There are two different types of disc brakes available for road bikes, hydraulic disc brakes, and mechanical disc brakes.
Hydraulic Dish brake
Hydraulic disc brakes work similarly to the motorbike or car.
Mechanical disc brakes
Mechanical disc brake work as rim brake. It means that you pull on a lever, which then pulls a braided stainless steel cable which is then used to apply braking force to the rotor. Mechanical disc brake systems are simpler and more refer to the entry-level bikes.
