Rear shock absorbent

Rear shock absorbent

Suspensions and rear shock absorbers have their peculiarities that the best bike us for details-

A great suspension is rear shock absorbent most part of a Bicycle. It must be good quality and best results for of cycling. So, we have always looked before and used it always best bike us.

Suspension X Shock Absorber

This distinction is very important to be understood. The suspension is the entire system of tubes and levers that make possible the movement of the rear wheel to absorb the impacts. The shock absorber is the element that absorbs the force of these impacts. Rear shock absorbing wheels of peace 10 years

Unlike the front suspensions, the rear shock must have different internal settings and sizes for each type of frame. This is because the frames can have a suspension system and different sizes and this causes the force to be absorbed to be smaller, larger or has a different progressivity curve. Currently, the regulation of these dampers is increasingly accurate for each frame, and internal changes are necessary to make better use of the system.

Let’s go over some important features.

Course Size

Unlike the front suspensions, it is not the damper that dictates the stroke (damping capacity) but the suspension system of the frame. The same buffer sometimes can give more course in one frame type and less in another. That is, to increase the stroke of the rear suspension, most of the time it is necessary to change the frame, not the shock absorber and you get more of the best bike us.


That’s another big difference for the front suspensions. The same damper model often has different lengths, which is to work on different frames (remembering that part of the frame integrates the rear suspension system). This measure is called eye-to-eye, in reference to the plug hole that exists at each end. It is mandatory to know the length of the shock absorber that a certain frame accepts so that the operation is correct.


Equal to the front suspensions, there are two main movements for operation: compression and return. The first is when the damper is compressed by impact with the obstacle. Already the return is when it returns to the original position.

Compression Elements

Elastomers:  These are very hard rubber pieces used to cushion the impacts. They are not very efficient and are hardly used in rear shock absorbent.

Springs: They are compressed to absorb the impacts and then return to their original size. Nowadays, due to the weight, the springs are only used in downhill dampers. In more expensive models titanium springs are used to reduce the weight and also because they have a longer life.

Air: It has the same principle of spring, having the advantage of not having weight. Nowadays it is the most used technology for rear shock absorbers.

Oil: It is usually used for return and in special valves. The advantage is that they keep the operation more constant; however, it weighs more than the other elements.

In case you don’t have an auto and for whom the bike is the essential strategies for transport, sooner or later, you will in like manner get a cycle bags regular-

Elements of Return

Usually, the return element is the air or oil, which are in separate chambers. These elements in the return function, instead of helping to dampen the movement, serve to control the speed of the suspension back to the original position.

Settings: Control of return speed: This is one of the most important adjustments of the damper. Without the return control, the suspension would dump the rider over the handlebar in strong impacts (this is often the case with wrong settings). Being able to have a sensitivity adjustment is essential best bike us for the suspension to work well according to the terrain. Remembering that one of the goals of suspension is to keep the bicycle wheel all the time on the ground, to maintain tire traction, especially when braking.

Lock: The importance of stopping the operation is to avoid loss of energy when pedaling in stretches where the absorption of impacts is not the priority, as in asphalt, slow climbs or in sprints. Nowadays, the pedal platforms are used much more than the full lock on the rear shock absorbent.

Pedal platform: This technology intentionally reduces compression with the same purpose as the lock, but the operation is not completely blocked. Some models have external controls to increase or decrease the sensitivity of the operation. Popularly it is called ProPedal in Brazil because it was the name given by one of the main brands in the market.

Compression Control: Controls the ease of absorbing impacts. A very soft compression makes the suspension reach the end of the course with ease. Already a very hard compression does not use the full potential of the damping. Suspensions with air compression usually do not have this adjustment, as it is enough to place or draw more air.

High-speed compression: In more specialized models, this adjustment controls the operation in situations of faster impacts, that is, when the impact is on larger objects and less rounded, where the suspension is very required. It usually helps avoid end-of-course situations in suspensions of more extreme use.

Low-Speed Compression: Also available in more expensive suspensions, it is used to regulate operation by reaching smaller obstacles, ie to prevent the suspension from operating without much need.

End-of-Course – Bottom Out: Some more specialized dampers have extra regulation to improve end-of-stroke compression performance. Unlike high-speed compression, this setting works only when the stroke is triggered almost to the end.

Inertia valves: This system, called in some brands of the intelligent valve, allows the automatic operation of the suspension only when there are obstacles. That is, when the terrain is not very bumpy, the suspension remains locked, and when it becomes technical, it triggers the operation. Some models also allow the adjustment of the sensitivity of this operation. They are more present in front suspensions but already appear in rear suspensions, as in the System of the Specialized Brain.

Tips: It is very important to observe the pressure limits of the air dampers. Some models operate totally differently from each other and moving beyond the maximum pressure can cause irreversible damage to the shock as well as using it with less air than recommended the best bike us.

Curiosity: Saddle Damper – These rear shock absorbent do not have the same function as the shock absorbers in the frame. They serve only to bring a little more comfort when the cyclist is seated and only on tour bikes. Wheel dampers aim to absorb impacts to maintain traction during braking and in technical stretches, with comfort being a side effect.
