Stroke travel: This is how much a rear shock compresses. It is comparatively short: 1.5” to 3”.
What is my shock travel?
What is shock travel? Shock travel measures a shock’s movement through both compression and extension strokes. Compression means the shock’s piston rod is pushing up into the body of the shock, shortening (or compressing) in length.
What size rear shock do I need?
Is 160mm travel too much for trail riding?
160mm of travel is only really needed if you’re hitting big hucks, or you’re smashing really long bouldery fast descents. Do I need 160mm travel? 99% of the time, no.
Is 120 enough to travel?
In addition, you’re not likely to notice much difference between a 120mm, 130mm, and 140mm fork. Honesty, a 120mm fork is enough travel for most Trail riders.
How do you calculate rear suspension?
Cycle the travel through the range and measure the distance from floor to the rear axle at top and bottom positions, then subtract. So it really is as simple as releasing the tension from the shock and measuring the distance the wheel travels when the shock is fully extended to fully compressed.
How much up travel should a shock have?
Summary Notes: –1/3 to 2/3 of the shock should be up travel. -Do not exceed 9″ of droop. -14″ shocks are most common, then 12’s, then 16’s.
How is rear wheel travel calculated?
Mount the bike on a bike stand(if you have one), remove the shock, cycle the rear arm and measure. Presto, there’s your travel.
What is a rear shock?
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.
Are rear shocks universal?
For a rear shock, you have to match up the top and bottom for the shock mounting hardware. There are no standards and every brand chooses what they think works best with their design. So what’s usually best is to either look at the brand’s website or contact the manufacturer to get the correct shock hardware.
Is stroke the same as travel?
Shocks don’t have travel–they have stroke, which is the distance the stanchion can move within the shock’s body. Think of travel as the axle’s range of motion. For the front wheel, travel is only a function of the fork’s stroke. That is to say, for forks, stroke and travel are the same thing.
What PSI should my rear shock be?
The exact PSI you end up with depends on how plush/firm you want the rear shock to be, but a good starting point is 1 psi for 1 lbs in weight of the rider (including riding gear).
How much difference does 20mm of travel make?
As a rough estimate, each 20mm of travel added will correlate to a one-degree difference in the head tube angle.
Is 140mm travel too much?
140mm of travel is not much in real terms…its just like a slight bend of the legs… I think many people get caught up in exactly how much travel to use. The important thing is that the travel you use suits the bike design and wont spoil the angles or turn it into a “chopper”.
Is 150mm travel enough for Enduro?
What should I look for in the best enduro mountain bikes? An enduro bike is basically a mountain bike with at least 150mm of suspension travel, but more commonly 160-180mm. They’re built for the rigours of racing full-bore downhill whilst being sufficiently efficient on climbs and contouring trails too.
Is 100mm travel enough?
Depending on your skill, riding style, and terrain, there is likely an ideal amount of suspension travel. Other specs such as geometry, wheels, and tires matter too, but they are usually tailored to match a bike’s suspension. Most modern mountain bikes will have somewhere between 100mm and 170mm of suspension travel.
How much travel should you use?
Set sag between 20-30%. If you only ride smooth trails, you should still use about 3/4 of the travel. Measure this, since the exposed stanchion is longer than fork travel. If you start to ride harder or start to ride rougher trails and bigger drops, you will need to add air.
What does 120mm travel mean?
travel is how far down the fork can compress (how much shorter it will get when it is pushed as far as it will go) like spawne said, short travell (usually 120mm or less) is for cross country, medium (130-160mm usually) is for trail, or all mountain riding. anything 160mm or more will be for downhill or freeride.
How do you calculate suspension travel?
The distance traveled from bump to droop as measured at the hub will be your suspension travel. Rear – With leaves, jack your truck up so the tires are off the ground, measure from the top of the axle tube to the frame. That is the amount of possible travel you have.
How do you know if your rear shocks are going?
You can measure the stroke length by subtracting the eye to eye length when the shock is fully compressed, from the eye to eye length when the shock is fully extended – you should get relatively close to the shock’s stroke length.
How do you test for suspension travel?
Measure your suspension travel by putting electrical ties on the shaft of your shock. Push it all the way agains the shock body when the car is at rest. The compression of the shock will push the tie wrap up and give you a water mark of how far it was compressed.
How do you increase droop travel?
Adding preload will increase droop travel (given enough damper stroke length) but lose bump travel and vice versa. Spring free length and rate will have to match the damper stroke available to get the optimal travel.
What happens if your shocks are too long?
If the extended length of the shock absorber is too short it will “top-out” and reduce the extended travel. “Topping out” is the term used when the piston inside the shock absorber collides with the cylinder head.
What is full droop suspension?
What is rear travel on a mountain bike?
“Travel is the maximum distance that the front or rear suspension can compress before bottoming out.
How do you adjust rear shocks?
What is rear wheel travel on a bike?
“Travel” refers to the actual distance the rear wheel can move when the rear suspension is compressed. This is different than “stroke.” Stroke refers to the distance that the shock’s shaft compresses. Rear suspensions on different bikes use different ratios of leverage, which equate to different lengths of travel.
