Difference between center and “true centre”

no. some people are dumb as shit and will mount your skis on the factory recommend if you ask for center tho. apparently "center" is supposed to be the center of directional camber or smth and not the measured center of the ski shrug emoji

For the most part skis have three centers- the core center, the waist, and "true" center. The naming convention isn't official but the concepts are real. The core center is the thickest part of a ski, or in the case of a profile with a plateau, it is the center of the plateau. The waist is the narrowest part of the shape of the ski for a classic symmetrically shaped ski. For, an asymmetrical ski, there could actually be two sidecut centers, but that's a bizarre tangent and not relevant- not in 2017 at least. Then there is the "true" center, which is the important one for people spinning into the future. True center can be determined with a tape measure, right in the middle of the length measurement. Finally, there is the longitudinal inertial center. If you really care about your knees and lose sleep over tenths of millimeters, you'd actually find the balance point of the ski and call that inertial center. If you are doing that you also are probably spending sleepless evenings thinking about where on the boot you should be aligning these marks anyways, because using the midsole line on your boot probably doesn't optimize your anatomical dreidel-ness.

True there is actually effective edge center and running length center, and recommended center. Long story short, if a shop is mounting your skis, make sure that you mark exactly where you want your midsole to line up for them. Words are hard.

I'd also like to add that many ski companies have discrepancies their labeling of where center actually is. If you are gonna tell a shop you want it at one of the recommended mount points, I suggest standing the skis up together and ensuring the points are at the same point on the ski.

Also note that some brands are better than others about this, but still it doesn't hurt to check.

I use a cardboard template of my boot sole so I can find the centre of gravity for ski + binding before marking the holes.....it's like you've known me my whole life.

Thx

True center is measured using a microscope for optimal mounting accuracy, regular center mounts are for poor people.

True center is the center of the full length of the ski, while center is usually chord center, which is the center of the core of the ski.

Camber center - center of camber.
Measured center- just as it sounds.


That's all it is and the rest of you are fucking idiots.
