How do you read a mountain bike shock size?
A shock that measures 210 x 55 means that the shock is 210 millimeters long and uses a 55mm stroke. The length of the shock is measured from eyelet to eyelet, while the stroke of the shock is the amount the shock can physically compress.
How is mountain bike suspension measured?
“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 the stroke length of a rear shock?
Stroke length refers to the total distance the shock can compress. 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.
Can I put a bigger rear shock on my MTB?
The longer the rear shock, the more oil will be available to absorb the shock better. In this scenario, it does make sense to buy a longer rear shock. There will be more oil and space to absorb a lot of the movement of the bike while riding.
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.
How do you measure front suspension?
Raise the wheel to ~4” above ride height (measured vertically), record the exact compression. Measure and record the distance between the shock mounts. The amount the shock moved between droop and bump divided by the amount you moved the wheel is your motion ratio.
What happens if your shocks are too long?
The other problem is that if the shock absorber that has been fitted to the vehicle is too long, in this case the vehicle suspension could experience the shock absorber “Bottoming out”. This term is used when the shock absorber is fully compressed, but the suspension still has an allowed amount of travel to go.
How do you measure front suspension on a mountain bike?
If you are trying to measure total travel you will have to let the air out to easily cycle the fork through the entire range of motion. Use a zip tie around the stanchion to make the measurement. Push the zip tie down to the wiper seal and then compress the fork all the way. This is your total travel.
Is 120mm travel enough?
Honesty, a 120mm fork is enough travel for most Trail riders. Longer travel doesn’t necessarily mean better.
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. What’s really useful is decent geometry, and unfortunately the vast majority of bikes with decent geometry are on 160mm travel bikes.
