Quick Answer: How does a rear mountain bike shock work?

The force created in the positive chamber works to counter the weight of the rider. As your rear wheel moves through its travel, the seal head slides up the piston shaft and compresses the air in the positive chamber, creating the spring.

How do rear shocks work?

Rear shocks consist of two telescopic tubes which slide into each other, a spring of some type and an eye at either end through which the whole mechanism is affixed to the frame. A small bushing (a type of simple bearing) in each eye enables the shock to pivot smoothly when the suspension is active.

How do you adjust rear shocks on a mountain bike?

Setting your rear shock sag

  1. Bounce firmly up and down to charge the negative spring and free up the travel.
  2. Assume your normal seated position and after allowing the bike to settle for at least 5 seconds have your assistant push the rubber O-ring on the shock stanchion up (or down) to the rubber wiper seal.

How does mountain bike suspension work?

The suspension lets the wheels move up and down to absorb small bumps while keeping the tires in contact with the ground for better control. It also helps the rider and bike absorb large shocks when landing jumps. Both the front and rear suspension systems contain two essential elements: a spring and a damper.

How long do rear shocks last?

This means that your shocks or struts will last longer if you drive fewer miles, drive on nice smooth roads, don’t drive like Speed Racer, and don’t carry a lot of weight in your vehicle. On average, if your car has been “babied,” you can expect your shocks/struts to last about 10 years.

Can I replace rear shocks only?

It’s not necessary, but it’s usually recommended to replace them in pairs, for example, both front struts or both rear shocks. … However, if your car is not very old, replacing only one strut or shock absorber may be enough, since the opposite side is not worn out yet.

Can I put a longer rear shock on my mountain bike?

Can you put a longer rear shock on your mountain bike? Take some measurements to make sure a shock matches your bike height, weight, and overall movement. If you put too long of a rear shock, it can negatively affect your comfort. Do it right, though, and you’ll be able to absorb a lot of the shock well.

How do you measure a rear shock on a mountain bike?

The most accurate method for shock measurement:

  1. Measure the eye to eye length.
  2. Attach a shock pump and slowly remove all the air from the shock.
  3. Compress the shock fully and measure the eye to eye length again.
  4. Subtract this measurement from the initial eye to eye length to find the usable stroke. (ie. 185 – 132.5 = 52.5)
