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

How do you measure rear shocks?

“The best method for measuring frame travel may be to remove the shock and measure the vertical travel at the rear axle, with the suspension linkage at the full shock length, and at the shock bottom-out length (original eye-to-eye minus manufacturers specified shock stroke).

How do you measure shock length?

A shock is measured by its extended and collapsed lengths, and is measured from the center of the loop mount or the base of the stud mount. To get the extended length of a shock, remove it from the vehicle and allow it to expand on its own or pull it to the fully extended position and take a measurement.

How do you measure rear shock mounting hardware?

One way to measure the width of the shock hardware is to measure the distance between the shock mounting tabs on the frame of the bike. To get the same measurement, you may also measure the width across the shock eyelet. Lastly, to find the shock bolt diameter, measure the inner diameter of the hardware eyelet.

Can I put a bigger rear shock on my bike?

If you buy a shock that is too long for your bike, it will work well, but it can also damage it. The shock may be too long if your rear tire has moved at all after you installed it. Parts of the frame of your bike may also touch that aren’t supposed to, causing unnecessary damage.

What happens if your shocks are too long?

If the shocks are too long for the springs you’re running, the springs can become unseated when your suspension droops.

Are shocks and coilovers the same thing?

In some cars, the coil spring is located apart from the shock absorber, supporting the vehicle on its own. The shock is mounted separately from the spring. … In fact, coilover is just a shortened version of “coil spring over shock absorber,” and sometimes coilovers are indeed struts but not always.

How do I choose shock absorbers?

Six Steps for Sizing Shocks

  1. The first step in selecting a shock absorber is to gather all of the required information to size the shock absorber properly. …
  2. Calculate the work energy in the application. …
  3. Determine the total energy ET that the shock must convert in one hour. …
  4. Determine the shock force, Fp (lb). …
  5. Calculate this g-load:

What spring rate should I use?

Springs should typically be compressed 25-30% of the free length when supporting the weight of the vehicle. Drag race cars will normally use a lighter rate spring (about 30%) to promote weight transfer while a street car will use a firmer rate spring (about 25%).

What happens if your shocks are too short?

If the extended length of the shock absorber is too short it will “top-out” and reduce the extended travel. … Damage to the upper and lower shock mounts. Damage to the cylinder head and the unit may leak oil.

How much up travel should a shock have?

The amount of shock travel needed depends on the type of suspension you are working with (solid axle, or independent) so it is best to consider wheel travel as well. Most street driven vehicles should have a minimum of 2.5-3” of compression travel at the wheel and 2-2.5” of rebound travel as a good rule of thumb.

Do I need longer shocks for a 3 inch lift?

Suspension lift kits that raise your truck higher than 3 inches will usually require a new shock absorber to take up the difference in distance between the top and bottom mounting points of the shock. To simplify the shopping experience, the majority of brands we carry will include new shock absorbers in these cases.

What is the best rear shock for a mountain bike?

  • Fox Float DPS 3-Pos Adj Factory: Best Overall. A gold standard XC shock that offers fantastic control. …
  • EXT V3 Storia Lok: Best for advanced riders. A stand-out shock that comes with a custom tune. …
  • Ohlins TTX: Best improved design. A fairly expensive shock that delivers structurally stiff, but sensitive performance.

What is metric shock sizing?

“Metric,” as it’s referred to here, is actually a new set of sizes for rear shocks that have been agreed upon by several suspension and frame manufacturers. That means new eye-to-eye and stroke measurements in conveniently chosen increments of millimeters.

Do new shocks come with bushings?

Most shocks will come with fresh hardware, locknuts and rubber bushings, which I recommend replacing even if the old ones look fine. … Remove the upper bolt from the shock’s central damper rod and remove the shock from the vehicle. Important: Now you can check the upper bearing, if you have one, for wear.
