Rear shocks can be purchased in a large amount of spring tension choices and shock absorbing ratings, as well as various placement options and shock materials. Frequent bike shock things to consider are: shock rebound, dampening quality, bottom out resistance, and liveliness of the shock build. Produced by many top bike brands, such as RockShox, Fox Racing, and Manitou, you can find rear shocks here from the top mountain bike part makers at enticing low prices. Rear shocks are meant for mountain biking, though they have other bike setup applications if you have the creative bend. Start with the rear shock damper in a mountain bike shock absorber. The damper pumps oil through small holes, doing so in time as the shock piston oscillates up and down. Now if your bike suspension were equipped solely with a simple spring, it would just bounce up and down many times after each and every bump you hit while riding. The rear shock damper is the actual part of the shock design that dissipates the energy transfer, while keeping your bike suspension from bouncing wildly out of control as you ride. The most typical damper you'll find is oil-filled, which happens to work best in rear shocks to manage rough terrain while mountain biking. The effective part about oil-filled dampers is the fact that each will dissipate more energy while simultaneously giving more resistance to excessive motion. And this is true, believe it or not, the faster that rear shock absorber is compressed. When the rear shock compresses faster, a greater overall amount of fluid volume must flow through the main shock orifice, and thus more pressure is required to force that fluid through to activate the shock's ability. This increases the stiffness of your bike suspension, because it resists the motion of the shock absorber, and it also serves to dissipate additional energy. Designing a good rear shock concerns finding the approriate balance factoring the spring rate, which is the stiffness of the rear shock spring, in relation to the damping quality of the rear absorber. That's why many rear shocks are adjustable, so that you can fine tune the amount of shock absorption they apply. Be sure to weigh all of this, particularly the choice of damper and the ability to adjust the rear shock, when choosing your shock. Your rear shock should be packaged with full instructional materials for how to install and maintain it on your mountain bicycle. The rear shock is part of your MTB support system and helps make mountain bike riding more enjoyable. Rear shocks are compatible with most every downhill or other mountain bike design or major bike brand. Set up your mountain bike with a rear shock, or at least maintain and replace it as needed, to max out your ability to tear up the trails when you're bombing on a mountain bike ride.
