Summary Notes: –1/3 to 2/3 of the shock absorber should be the spring deflection. -Do not exceed 9″ of deflection. -14″ shocks are most common, then 12s, then 16s.
How much travel should a shock have?
For this reason, the rear suspension on most cars with a live axle should be equipped with a shock absorber at least five inches of travel, while the independent front suspension can only use three inches of travel.
How long shock do I need?
What is the travel of the rear shock?
The journey is a function of the stroke length of the shock and your frame. My bike comes factory fitted with a 230mm x 60mm rear shock. The 230mm is the distance between the lugs on the shock and the 60mm is the stroke length (how far the shaft travels between full extension and full compression).
How do you know when your shock absorbers are on their way?
How to increase droop travel?
add preload increases droop travel (with sufficient shock travel length) but loses shock travel and vice versa. The free length and spring rate of the spring must match the available damper stroke in order to obtain optimal travel.
Is 160mm travel too much for trail riding?
160mm of travel is only really needed when you’re riding big hucks or tackling really long, rocky fast descents. Do I need 160mm travel? 99% no.
Is 120 enough to travel?
Also, you probably won’t notice much of a difference between a 120mm, 130mm and 140mm fork. Honesty, A 120mm fork will suffice for most trail riders.
Is 170mm travel too much?
But yes, 170mm is enoughyou’re into DH-esq travel, but if you think you could make use of it or help you get a shade more then there’s no harm in trying.
What do off-road shock absorbers do?
Technically shocks convert kinetic energy into thermal energy. Shock absorbers are also called “damper” because they absorb the energy of the spring. By resisting the up and down movement, the dampers convert kinetic energy into heat and then dissipate the heat to the atmosphere.
What happens when your shocks are too long?
When the extended length of the shock absorber is too short it will “pad” and reduce the increased travel. “Topping out” is the term when the piston inside the shock absorber collides with the cylinder head.
How is travel suspension measured?
Measure and record the distance between the shock absorbers. Raise the wheel approximately 4 inches above the ride height (measured vertically) and record the exact compression. Measure and record the distance between the shock absorbers. The amount the damper moved between the droop and bump divided by the amount you moved the wheel is your move…
How do you calculate the cycle path?
Since the perimeter is equal to πx D, it is equal to: 3.14 x 3.125″ = 9.81″. If the wheel turns 9.81″ in one revolution, it would travel: 9.81″ x 3.625 revolutions, or 35.56″ total.
How is Fox travel measured?
How do you measure the stroke length of a rear shock absorber?
Stroke length refers to the total distance the shock can compress. You can measure the stroke length Subtract the eye-to-eye length when the shock is fully compressed from the eye-to-eye length when the shock is fully extended – They should get relatively close to the stroke length of the shock absorber.
How do you calculate rear suspension travel?
“Perhaps the best way to measure frame travel is to remove the shock and measure the vertical travel at the rear axle with the suspension linkage at full shock length and shock bottom out length (original eye-to-eye minus dated manufacturer specified shock stroke).
Is stroke the same as travel?
Shocks have no travel – they have stroke, which is the distance the post can move in the body of the shock. Think of travel as the range of motion of the axle. For the front wheel, travel is only a function of fork travel. This means, For forks, stroke and travel are the same.
How is rear wheel travel calculated?
Mount the bike on a bike stand (if you have one), remove the shock, ride the rear arm and measure. Presto, there’s your journey.
What is travel in suspension?
Travel is defined as the maximum vertical distance the bike can travel from the fully extended “rebound” condition to the fully compressed “full bump” condition. “Bump Travel” is defined as the distance traveled by the center of the wheel from normal ride height to full bump condition.
How is the spring travel calculated?
Let’s say you run 24.5mm from the top of the axle, your subtracted number is 9.1mm. Finally, subtract your ride height. If you ride 5mm of ride height, your actual drop is 4.1mm.
What is a droop setup?
Droop is the amount of downward movement a wishbone has. Droop can be independently adjusted front to back, but should (usually) be the same side to side. voices with droop. Typically, less droop reduces body roll. Less rear will free up the rear a bit and give more steering.
How much difference does 20mm of travel make?
As a rough estimate, each added 20mm of travel is equivalent to a a degree Difference in head tube angle.
Is 140mm travel too much?
In reality, 140 mm of travel is not much… it’s like bending your legs slightly … I think a lot of people are overwhelmed by how much travel to use. The important thing is that the travel you use suits the bike design and doesn’t compromise the angles or make it ‘chopper’.
Is 150 mm travel enough for the descent?
Long travel bikes typically have 150-170mm of rear travel to handle hard descents. Front travel is often equal to rear travel but can sometimes be greater. Trail and enduro bikes fall into this category. They absorb big hits and smooth out rough terrain.
Is 150 mm travel enough for Enduro?
Slide Trail will be absolutely fine. 150 mm travel in the fork is sufficient! You will surely have a lot of fun. If you’re the biker for big jumps & drops and bike parks, the Swoop is a great bike.
What does 120mm travel mean?
Travel is how far the fork can be compressed (how much shorter it gets when compressed as far as it will go), as Spawne said, short travel (typically 120mm or less) is for this cross country, Medium (typically 130-160mm) is for trail or all-mountain riding. Anything 160mm or more is suitable for downhill or freeride.
How Much Travel Should You Use?
Adjust the sag to 20-30%. If you only ride smooth trails, you should still use about 3/4 of the suspension travel. Measure this because the exposed upper tube is longer than the fork’s travel. When you start riding harder or riding rougher trails and bigger drops, you need to add air.
