When you glance at a bike on any best bicycles online shop, it looks simple and sleek. However, there are various mechanisms, tools, terminologies, and names that might seem unfamiliar and confusing. Understanding these terms and mechanisms, especially the parts of a cycle, is necessary for making the correct purchase.
In this article, we’ll explain all the parts and the mechanisms of a bicycle to assist you in making an informed decision. Whether you want to purchase an impressive all mountain bike for an adventurous ride or need a sleek, stylish road bike for everyday commute, this guide can be helpful.
Let’s get started!
The Fundamental Components Of A Bicycle
The Frame- Front and Rear Triangle
A bicycle’s frame is divided into two parts- the front triangle and the rear triangle.
The front triangle encompasses the top tube, down tube, and seat attachment tube of your bicycle. The size and the fitting of the bike are determined by these tube measurements.
The front triangle includes the entire bottom bracket. In an all mountain bike and certain hybrid bikes, the suspension components are also included within the front triangle.
In hardtails and road bikes, the rear triangle is attached to the seat tube. The rear triangle houses the seat and chainstays.
While in most off-road models, the rear triangle isn’t attached to the suspension system, and the rear triangle components are linked to the seat tube. Therefore, the rear triangle remains floating, enabling the rear wheel to travel up and down.
The tube is the front tube of the bicycle that houses the ball bearings (headset) for transmitting the steering movement. The head stem and the handlebars attach to the headtube.
The “headset” is the bearing component in the head tube, allowing you to steer and rotate handlebars while riding the bicycle to change direction or make a turn.
The headset bearing can vary in size depending on the type of bicycle and your requirements.
Hadsten is the part of your bicycle that is inserted into the head tube. The head stem supports the handlebar and controls the comfort while steering and handling your bicycle. The height of the head stem can be adjusted based on the cycle model and individual riding requirements.
Most on-road and commuter bikes have a 90-110mm long stem, while off-roading and trail bikes feature a stem length between 35 and 70mm.
The handlebar denotes the arms attached to your head tube, which you hold onto while riding a bicycle.
When you visit the best bicycles online shop, ensure to examine the handlebar width and height. These two measurements determine your bike’s handling comfort and convenience.
A bar width controls the stability of your bicycle. A wider width will enhance stability, while a narrower width can increase the steering speed.
The major and the most fundamental components of your bike- wheels. In the ancient era, bicycle wheels were engineered with wood or steel. However, with the discovery of pneumatic tires, the wheel built switched to the modern, sleek, lightweight wire wheel design.
The main elements of the wheels include the hub, rim tires, and spoke. The hub is the heart of your bicycle’s wheel and houses axle, bearings, gear systems, etc.
Drive Train And Gearing System
Drivetrain and gearing mechanisms are responsible for transferring the power from your legs to the mechanical components for moving the bike forward.
The drive train mechanism can be decided into three major sub-components:
- Power collection system encompassing rotating pedals (footrests) on the geared wheel
- Power transmission mechanism enabling power collection and transmission from the pedals onto a chain, chainless belt, or shaft.
- Speed and torque conversion systems encompassing gearbox, shifters, or direct single gear connection to the rear wheel axle. This system transmits your pedaling speed to the ground allowing movement.
When you browse through the collection of any best bicycles shop online, you can come across the three most popular braking systems:
- The rim brake features rubber pads for clamping the rim and slowing the bike.
- A disc brake utilizes calipers for clamping the pads on a disc attached to the hub.
- Kickback or coaster hub is engineered with brakes that expand brake shoes inside the hub for slowing your bike.
Disc brakes are the most prevalent brakes in almost every all mountain bike. Disc brakes are typically available in either hydraulic or cable variations.
Cable discs use cheaper, simpler, and more basic mechanisms. As a result, cable disc brakes are easier to maintain. Generally, the cable disc brake uses a brake cable. It is most suitable for daily commuting and light off-road use.
Hydraulic discs, on the other hand, utilize sophisticated braking systems similar to a motorbike or car. Hydraulic discs enable supreme power braking mechanism, greater modulation, and reliability.
Unfortunately, you’ll require specialized tools for maintaining and servicing the hydraulic disc brake system. Aggressive all mountain bikes or sometimes racing cycles feature hydraulic disc braking.
Also known as mechs, front or rear derailleurs shift the chain between gears.
Seating Post And Seats
Seats and seating posts are available in innumerable configurations. Some seating mechanisms offer extra comfortable and padded style, while some feature a more rigid and narrower style toward the front to offer more driving and more space for leg movements.
Whenever you search for a bicycle online, examine these parts to better understand a bicycle’s anatomy and make an informed purchase decision.
