you only get one back
take care of it
( I sound like you mother )
lol

humping power
all the way

yes you can put powerskips on a Zer frame
you just have to change the spring bolts to 5mm
because the skips use a smaller bolt than the Zer frame
or 7's or Sers all but upwings

as long as they last 4ever and make you jump higher
bring on the witch springs

I don't think he has a lot of money
so I think changing the springs can solve his problem with little money spent

I do front flips on the ground like that with speed but on bocks you need height because of the extra weight  you will get it
good job to get it on camera

I bought the poweriZer pro
the springs are total crap   
I shattered them in about 5 hrs
I then bought the PoweriSer springs for around 100$
I weigh 198 to 200 and I am 6'2''
the springs were the 90120's
just like  XS has
they do bottom out but you can limit your force
and jump 4 to 5 ft
that is more enough to do flips
I live in chino ca
were are you located

vegas sounds so cool

I think we would all like to try the new spring

it is the capital of gambling
and losing money
this a good idea
bockers unite
there are tons of  performers that use bocks in shows
does anyone know some

I live in chino ca   about 40 miles from la
a get together sounds cool

Is there an english version
for the stupid people like me that can't read german
and i hope this is the spring to end all springs
and the price? any ideas on time frame for testing to be complete?

the smaller bolts are the way to go
you dont have to worry that you will damage
the skip springs 600$ or 650$
the bolts that work are the  5mm size for skips

everything looks good
just get out and bock
if it breaks get something better
but only then
where in the us are you again?

i think they are good to go

reading is good

are the 7's better
that the 720's

compared to the PS720s so i dont think they are as powerful.

I mean for the money and life of the spring the 7's are better
If they last longer with avarge use.
i would say the 7's are better
