Guest naj Posted November 29, 2007 Report Share Posted November 29, 2007 i got a board where it says it has a 155 effective edge. however when i measured it using that insert-papper-under-the-board-method, i it measured 150 BUT when i tilted the board sideways (around 50 degrees sideways), the effevtive edge now measured 155 question: which is my real effective edge length?

groovastic Posted November 29, 2007 Report Share Posted November 29, 2007 i guess the 2nd eff edge should be measured from the widest part of nose to the widest part of tail if i'm not wrong i don't know how you got different results, but i guess the 2nd method can't be wrong Quote Link to comment Share on other sites More sharing options...
pebu Posted November 29, 2007 Report Share Posted November 29, 2007 The first method doesn't take the camber in to account... Which when you're on it and making a turn, the board should be decambered and that changes things again... But I have a feeling I know what accounts for the 5cm. The effective edge isn't the measurement between the nose and tail straight away, it's the arc-length between the two, or the measurement along the edge between the nose and tail. A straight line is the shortest distance between two points, but unless your board has a near infinite scr, the edge distance will be longer than the straight distance.

You effective edge is 155cm. Quote Link to comment Share on other sites More sharing options...
Guest naj Posted November 29, 2007 Report Share Posted November 29, 2007 ...will i detune on the point where the paper made contact with the edge with the first or second method? Quote Link to comment Share on other sites More sharing options...
D.T. Posted November 29, 2007 Report Share Posted November 29, 2007 so if i were to detune...Why detune? I'll take all of the edge that I can get. Quote Link to comment Share on other sites More sharing options...
Guest naj Posted November 30, 2007 Report Share Posted November 30, 2007 Why detune? I'll take all of the edge that I can get. i don't really like the hooky feeling when exiting a turn and the sudden turn initiation...i'm not gonna take of a lot of edge though but ok i know wher ur going at... however, if i want to find the center of the board so i could set up the bindings properly, which of the two measured lengths should i use?

bobdea Posted November 30, 2007 Report Share Posted November 30, 2007 ...will i detune on the point where the paper made contact with the edge with the first or second method? do not detune....... that hooky feeling is probably due to other issues, could be rider related or stance issues. the last board I detuned was a 190 I was trying to manage on terrain that we had no intent on opening because the snow was that bad. I in recent years have stopped detuning because CMC and a PSR told me so they were right. Quote Link to comment Share on other sites More sharing options...

Don't detune...you simply need to bevel the the edge. If you want you can bevel only a little bit of the tail edge. Say from 2cm inside widepoint to 15cm from widepoint. Bevel the base edge to 1deg more than what it's at now. This will be harder to maintain than setting the entire edge (base edge and then side edge) to 1 and 1 (1deg base, 1deg side). Detuneing is simply dulling the edge and that's not great for a freerider. J Quote Link to comment Share on other sites More sharing options...
Guest naj Posted November 30, 2007 Report Share Posted November 30, 2007 i undertand why some dont detune...but it works for me and i rarely encounter ice... but still my prob is that i have 2 ceters on my board:freak3: Quote Link to comment Share on other sites More sharing options...
