Breaking in springs is a myth!!

[Trip Master]

Athol, on your vids you have got some great height on ya Raptors. Activating the spring means that your getting a good energy return. I would like to see your results on the T Rex on video at your body weight. I suspect 2 things 1. You will initially be able to get higher jumps for about 3 -5 mins then 2. you will get tried very quickly and not be able to activate the spring or get any serious height! I know you think i'm wrong but i would love to see the results on video!

[Athoul]

Yeah, i am also very interested to see how i will get on with some t-rexs and am eagerly waiting for a go on them.

Also the only video that shows me on my raptors was the vaulting one and on that i was holding onto the rail when jumping 
I will however be uploading a new video showing my progress on my raptors shortly.

Out of interest (I may have got this bit wrong) I believe that there are 2 factories producing Bocks

one in Korea and one in china

Now poweriSers are Korean ? and PoweriZers/pro-jumps/all the others are china please correct me if I've got this wrong

Question where are 7's springs made and where are Skips springs made

I assumed that 7's were from the korean and skips either made as specials from korea or made in germany (hence the high price ) does anyone know the truth

Yes, poweriSer are Korean and made by Hitech & C, co.
PoweriZer/FlyJumper/ProJump/JollyJumper/AirRunner/SpeedJumper are chinese and made by FlyingLocust.

7's parts are made in Africa and China, and then assembled in Austria before being shipped out by Future tech under the name 7meilensteifel Pro.
PowerSkips are German, and are manufactured there by ALAN Sportartikel GmbH.

[Trip Master]

The 7's springs are completely independant from all the other factories. The Powerskip springs are excellent and made under Alan Sports control the same is true of the 7's under the control of the Austrian producer. Do not get them confused with the Fly Jumper or PoweriSer they are completely differant.

the company that sell's poweriSers is based in Korea but they've moved their manufacturing to the Philippines

[Jason R]

Thanks Sprog If the springs are made in a different factory to a different spec then that would explain why they react differently

I used to help mold parts for kit cars and the size ,quality of glass cloth and the methoud of laying it up into bodys could make the world of difference to how the pannels flexed of cracked under stress also there are so many different resins now days that a slight change can have a radical effect

[NathanCooper]

hey, i heard of someone, sprog i think, that if you put them in heat they jump higher because the particles move more, but the more you use them they do get alot me springier, mine used to be very stiff but now are great, good luck

[Mr Frank]

I gotta say there is a break-in time.  Maybe not for 7s and Powerskip, but I can say definitely for Poweriser.  When I got my Poweriser 7090s (I'm 70kg), I did not compress them when walking and the sudden, solid impacts on the ground were louder.  I do compress them now, and they make a softer sound.  When they were still new, one of the limiting factors for my bouncing was the extreme and uncomfortable G-forces I felt when jumping high on them, which I do not experience now.  The logical conclusion is that they are not as stiff as when I got them.

The logical conclusion is that they are not as stiff as when I got them.

Sorry, but this is exactly NOT necessarily the logical conclusion. The explanation might be different: The user learns/ improves and adjusts to the character of the spring (without realizing it). Especially beginners learn a lot within the first half year without really realizing it. Compare it with a car or bike (or skiing, skating ...). It takes months/ years to become a good driver but you can not really say what has been learned within this period, but it is a fact that the driver improves (e.g. internalize sequences of movements/ observations  which happens subconscious).

It might be true that Poweriser have to be broken in (to some extend). I have not used my Poweriser springs for a while so I can not remember exactly.

Usually it is the user who 1) learns/ improves and 2) has to get used to them. I have several springs (Powerskip E580 & E640, T-Rex, S-Rex, old Poweriser, Upwings, Flyjumper Carbons ...) and I often change them during the day and most time (yes most time) I have the feeling they get softer during usage. Sometimes it is just the opposite, I have the feeling that they get stiffer (I guess due to exhaustion). But this feeling is missleading, it is simply that I need around 20 minutes to adjust my technique & force. Also warm-up (of mucles) and fatigue have a bigger impact than any breaking-in.

For instance I am always surprised how much I have to change my movements concerning flips when I change springs. There is a big differnence between the springs and it takes a while to "feel" the reaction of the spring.

At least these are my personal observations.

[Pendragon]

Anyone got a mechanical device that could compress a certain amount of pressure?  Unless there's a better way to compare 2 springs new and used across an exact same playing field.  Or should we just send this to myth busters once and for all???

[bcicio]

I think this is a crazy argument.  Everyone knows the springs get softer with use.  All you have to do is try changing out only one spring once you have had the original set for a while.  I think "break-in period" is simply the time it takes for your springs to reach the point where you feel you are getting the best performance out of them.  If a person is experienced, and he/she can compensate for a new spring set right out of the box by adjusting his/her technique and get full potential right away - then naturally there is no "break-in period" for them.  But a beginner usually has a break-in period until their spring feels soft enough to get some better performance out of them.  It's just generally easier for newbes to learn when the spring is softer than brand new, hence the "break-in" period of a spring for them.

[nikki]

Correct me if im wrong but would it not be preferece too.
If you like them really soft then a "break in period" would be longer then someone who likes thiers a bit harder?
If that makes sense.
If so i dont have a "break in period" because i like mine a little stiffer (no stupid comments )
I have to lose weight so the harder i work on them the better!!

This is exactly what I doubt. A good spring does (hopefully) not get softer for a long period but stays as it is. That is IMHO exactly the quality of a good spring and that is exactly what I am looking for - constant quality. And I am convinced good springs work that way.

Of course there is a slow (hopefully a very slow) fatigue process where the spring wears out. But the question is: Is there a (pain in the a**) period which I have to overcome to reach the "good" character (= the breaking-in period). This period does not exist IMHO.

E.g. let us say the spring stiffness is 10 (whatever this means). Breaking-in would mean I need some time (weeks?) to get down to 7 and then my springs are good (=broken-in) and they stay at 7 for a while and then go down to 6. After a couple of months I am at 5. Finally they go down to a stiffness of 4,3, 2 .... (which means they are worn out).

This I do not want. When I buy a spring with the stiffness of 10 I decided to desire a 10 and I want to have a spring which stays at 10 over a couple of months (and does not change) but gets weaker slowly. After three months I am at 9 after four at 8 and at some point they are worn out and go down to 7,6,5 ....

Edit: If I am a beginner and need/want a stiffness of 7 why should I buy a stiffness of 10 and break it in? Wouldn't it be better to buy a spring with the stiffness of 7 and it stays that way. When I get better and the spring gets worse (at the same time) I will never (or only a short time) meet the point where skill and stiffness fit. When the stiffness stays as it is supposed to be, the period where stiffness fits with skills is longer. (I think I should draw a graph about that  )

[bcicio]

Well, sure.  We all want those types of springs.  But I think most people have experienced their springs getting softer over time.  Martin, you have springs that stay constant?  For how long and what brand?  My experience is only with the original Powerisers.
