    So how do you define a "drop?"

    Whenever people describe jumps and trails, they usually give a measured description of a drop... like "Dude, we went down an eight-foot drop!" I go to the same trail thinking that I have to fall the height of Yao Ming's extended hands only to see a ledge not much higher than my chest (and I am officially in gnome territory in terms of height).

    Maybe I'm wrong, but how are drops measured? Is it the delta between the highest point of the launch to the wheel's point of contact? Or in instances where the trail drops off considerably, would it be the bottom? Or am I just plain off my understanding? I tend to think that a drop requires some airborne time with the bike.

    The correct way to measure the size of a drop is from the lip to the top of the transition/landing. If you were to measure a drop base upon the amount of distance your bike has dropped, then you are no longer measuring the drop. Instead you are measuring the distance your bike has dropped. Usual mistake we hear is people saying " I just did a 8 foot drop!" when they actually just did a 3 foot drop with a steep transition.

    A better way to look at it is that a 3 foot drop has a minimum of 3 foot of drop for the bike, but with more speed it can easily turn into 8 foot of drop for the bike.

    I don't measure drops. The only thing I care about is if I clean it and if I can go bigger or smoother off it next time.

    Isn't Bender math the standard? Take actual drop and multiply by 2.5.

    he's pretty much right.

    Some people feel the need to measure the distance of the diagonal rather than the vertical to make themselves feel better. That's just silly.

    When it comes to riding with your buddies, I've found that the best way to communicate is "small drop", "big drop", and "Scary big drop".

    When it comes to reading about it on the internet, I've found the best way is "pics or it didn't happen".

    I'm thinking more along Monkei's lines too (nice art work btw).

    You generally measure a drop by the vertical distance from the height of the take off to where your rear wheel touches down. If you are going to label a drop as being a set height drop i'd probably say do it by the amount of vertical free-fall you have for a normal amount of speed taken off of the drop. The problem you are running into though is more about people exaggerating how big drops are.

    How much will it hurt?

    I measure drops by how much it will hurt if I don't clean it.

    Take for example the drop at the bottom of Corral into the trees, that thing is only like 2 fee high from the ledge, but if you air it from the top before it start going down, it is easily 3 ft plus.

    I thought I got to DH forum

    Anyway, Pinkbike rule is from the lip to landing zone (so everyone is claiming whatever they feel like)
    MTBR rule is from the lip to the closest ground as if you do slow speed wheelie drop and amount you flew over tranny doesn't matter. This way there is no ambiguity.

    For instance rolling bump is just what it is and not a drop. If you hit it hard you may fly some distance and even loose elevation if it's downhill, but it's not a drop regardless.

    Small drops with long tranny you can pre-test and go bigger gradually but drop difficulty remains the same. Big drop you have to commit for minimal clearing amount. So think about drop size as a minimum commitment level to hit it
    I used to run tubes like you are, but then I got thorn in my wheel.

    I define "drop" as a trail feature I can not roll down without both wheels leaving ground. I generally avoid those on a mountain bike. I have a little BMX to play, though I am not good at that either.

    I measure drops by placing them in two categories: "mkey" and "f-it".

    I took a drop from a curb to the street and it was like maybe four inches or twenty or five hundred feet.

    In conclusion: I am awesome.

    Drops are the same as how many women you have slept with? Dude that was like 8 feet or 2 women!

    Hands down, you have to be the best stick figure drawer I've ever seen.

    I printed up the photo to show coworkers how drops are to be measured, they ALL agree!

    I think the generally accepted way is from the take off point to the safest spot to land. So a 6ft drop, you could go 8ft and be fine, but it's still a 6ft drop, but if you land at 5ft, you're gonna crash cause there is a big rock. For bigger gap style drops, you can call it a 10x20, 10 feet out and 20 feet down, but then the math gets hairy, cause thats where the bs'ing begins. But that's what drives internet forums about drop sizes, so it's all a big circle..."the CIRCLE OF LIFE!!" sing it like Elton John in The Lion King...
