How do you measure a drop?

[Petzl]

A dumb question but I'm wondering. Is it from the top to where you first land, or is it the height of the vertical face you are dropping?

[Leifless]

:rolleyes: not another one of these...

[Petzl]

It's really that stupid? I'm serious, I don't know?

[RoBurban]

come up with your own way of measuring. if it's wack people will call you on it. just be honest?

[Chakalaka Rider]

This (http://www.pinkbike.com/modules/photo/?op=view&image=18874) is how you measure...:rolleyes: :rolleyes: :rolleyes: :rolleyes: :rolleyes:

Oh and check this out too...

hahaha you dont. just hit it and take a picture. people have eyes and everyone is gonna think something different. it's all good dude. no ones counting anywyas. :thepimp:

[JSinclair]

you measure the circumference of the drop.

To get the circumference you can multiply Pi times the radius, Squared

PiR2

:lol:

[Jake the Trog]

hopefully not with an nsmb ruler

[JoeC]

just measure the vertical feet, dont bother with how far down the landing you land, only gheys care about that to make their drops sound bigger.

"it was like 5 ft high, but i landedlike 10 ft down the landing , so i did a 15ft drop ":rolleyes: :nono:

[Zaskar]

i still think measuring drops is :r:

if it's big it's big. if it's gnarly it's gnarly. if it's not it's not.

i dont care how many feet it is, the height doesnt make all that much of a difference compared to the take off/tranny/run up/run out hahaha...a 3 foot drop and a 6 foot drop feel basically the same and i mean...if you wanna measure the distance go right ahead but frankl i dont see the point.

not to flat!

[Alexey]

i say vertical difference of take off and landing

[Dimes]

All drops start at 6 feet high, and increase from that point in correlation to how good you want people to believe you are.

[DangerBoy]

measure how big it is with a tape measurer......then add 3-5 foot to the actual height

[ronald55555]

measure from tyhe top of the drop to the bottom of tranny, plus 5 feet. If trying to show off to guys, plus 7 feet. If talking to a girl, plus 10feet.

[Faithless]

i just say

guesstimation (if thats even a word)

[Petzl]

That was interesting. All I was looking for was a means to quantify my little drop I mastered last night to what people talk about on this site. The plus 5' helps a lot so I did a 7' drop!:D

I mainly ride snowmachines and never bother to measure anything. But lately with all the videos and extreme riding (not just in snowmachining) they tend to put a number to their drops. I now know that is very subjective to the individual rider.

BTW, I am now officially a badass:thepimp: I think I'm going to drop a 10 footer tonight.

[well ridden]

top of the drop to top of the tranny

[EC Biker]

If you are the type of person who likes to quantify their progression, then putting numbers to everything you do is not necessarily a bad idea. I am one of those people, and I enjoy watching myself get better through the size of the drops I do and the length of the gaps I can jump. Do what you want, as long as it isn't for bragging rights.

As to measuring a drop, my method is to estimate the height just by looking at it, from the takeoff point to my rear tire mark on the landing. That accurately(depending on your estimation) determines the size of the drop you did.

Have fun.

[dhrider]

FROM LIP TO WHERE YOU LANDED, BACK TIRE

[EC Biker]

And there you have it.

[flizzy home dawg]

well you can measure it however you like top of trannie from top of drop middle of trannie what ever the point is if you do a 10 footer and make it 15 your bike felt a 15 footer and recieved the ware that a 15 footer gives your bike(if any) so really it should be top of the drop to where your back tire hits, but if you want to be cool and say it was only a 10 footer I don't care.

[bmxr]

What if you measure the diagonal? Like that you get some credit for the gap! ;) Pythagoras is your friend . . .

I always thought it was vertical feet(or metres :P ) between the take-off point and landing point, but maybe that's too simple to be interesting :)

[KING-OF E-VILLE]

I disagree with the PinkBike definition of a drop, I think it should be measured from take-off to landing point. regardless of vertical face/tranny stuff. justs start point to landing point on the tranny. thants how ski jumping is measured, thats how long jump is done.

I may bust 6' off a jump, that some dudes might be pullin 12' out of, (ie. the crater on fromme) I've seen some guys pull some huge drops of that puppy, but if you just measured the vertical portion of that jump, it would be like 4'-6'.

But really, who cares how it measures out. just ride hard, and brag about it later.

Dude! I like how you made an easter egg out of that last :rolleyes: (http://hackingthemainframe.com/gallery/albums/album55/Wood_X_D.sized.jpg)

That was very clever!

[drezy]

Since this is posted in the gear section, I thought the question was going to be how do you measure a "norco" drop. That's the only drop I would feel the need to measure, and usually they come with the size right on it.:rolleyes:

[fcf-spec]

How many of you have honestly taken at least physics 20 (grade 11 course)?

The height of a drop doesn't matter, if it's big then great... whatever.

In the ways of physics, a drop is the vertical distance travelled by an object. I see that some of you seem to think that its the diagnal... No cause thats a combination of your horizontal velocity off the take off and the vertical acceleration of gravity to your landing point. Thats a vector, not a drop. Diagnals are nothing.

If you really honestly want to measure the drop you did, you need to do 2 things. First off you need to find out the length of the gap (horizontal distance traveled) you did. So to do this, which you can't really do unless you had a ladder and a long tape measure, you gotta put one end on the edge/lip of the take off and then go straight out (totally horizontal) untill the tape lines up with the mark of your back tire, you need to have a birds eye view to know for sure.

From here you can do 2 things. Find the vector or find your vertical distance traveled. For the sake of being lazy, finding the vector is the easiest way. To do this you need to measure the diagnal, so put the tape on the lip/edge of the take off and put the other end to directly touching your back tire mark.

Ok then from here you pull out your notepad and pen, if your horizontal distance traveled was 20 feet, and the distance of the diagnal is 47 feet then you use pythagorises(sp?) therom:

A^2+B^2=C^2

In this case you gotta change that around to:

C^2-B^2=A^2

C^2 being the distance of the vector, B^2 being the horizontal distance travelled, and A^2 being the vertical distance travelled.

47^2-20^2=1809

square root of 1809 = 42.5

A^2 is equal to 42.5



This means that your vertical distance travelled is 42.5 feet, meaning thats a 42.5 foot drop.




See now we could all do it this way but why? Just hit the damn thing, style it, and keep riding.

[BAC5.2]

be it 3 feet or 6 feet, your body motion is exactly the same. The process is the same. So, to me, a drop is a drop. Moreso on a full suspension.

I can see how size matters on a hard tail. For that crowd, every extra inch counts, they need all they can get....
