This is the new thing that has got my skating blood racing again, i've been looking for hills and being
dissapointed so much, that this came along at just the right time.
I owe most of what i know of it to the guys on the NCDSA website (pumping forum check the link), so i will
tell you all i know sofar, with lots more to come.
PUMPING FORUM
The general idea is to get your stance so that your front foot is pretty much over the front truck
and push the front of the board from side to side. You are trying to produce the same effect that skiers and
skaters use, by pushing sideways on their skis/skates in our case the wheels to create forward momentum. I'm sure there is
a more technical way to describe it but this is how i see it.
In this way it is possible to pump your board long distance, mostly on the flat, but when your good
up inclines aswell, with the odd welcome break on a hill or two.
The boards and running gear are a little different, so i will show the setup i am using and try to
explain why it is the way it is.
This is the first deck i have set up for skumping, although i did try some other truck combos, this is the
end result of my messing about with what i had.
Its 36"x9", the multi drilled holes lets me try different setups and alowing a 3" nose (to the first truck
holes, this could be 4") and is nice and wide for good leverage.
The bolt holes are 25 3/4" apart which is about average and with the trucks set up the way they are the
wheel base is 26", the deck itself is made of 12mm 9ply birch, at the wheel base it has a slight flex.
Wedging is something i found out about when i was looking at how slalom boards are setup. On the rear of
the skumping setup i have used a mellow angle riser, made of hard plastic (these are mostly the same where ever you buy
them), this is with the lowest side facing forward to 'de-wedge' the truck, this puts the kingpin angle more perpendicular
to the deck, which in short makes it turn less. Ive used a shock pad to increase the hight aswell, to help eliminate
wheel rub.
On the front is a high angled soft urethane riser, this is also fitted with the thinner edge forward, but
when fitted on the front this makes the angle of the kingpin closer to parallel with the deck, in short making it turn more.
The soft riser helps with the bumps and there is no need for a shock pad as the angle of the hanger is more upright so making
it higher.
The trucks i'm using are a bit mixed up. I started with one Randal downhill 160mm truck and one
Randal RII 180mm longboard truck.
On the rear i have fitted the 30 degree downhill baseplate with the 180 longboard
hanger, if you use Randals you will know, but i have flipped the hanger which alows the use of another camber angle this
makes the truck turn less and also makes it more stable, i have used the Randal downhill bushings on this one. You can see
that the angle of the hanger is nearly horizontal, so it rocks more than it twists, which makes for a very stable but
loose rear end.

On the front is a 50 degree RII longboard baseplate, and the 160 downhill hanger, these hangers have a straight
camber, so are the same whichever way you fit them, you can see that the angle of the hanger is very apright, so it twists
more than it rocks, making it better turning and although not in this picture i have fitted a soft white barrel and a soft
white cone, both are made by Kiro, known as one of the best bushing makers with higher rebound urethane than most. Even when
these are tight, they alow for alot more movement.
The wheels i'm using at the moment are Abec11's 65mm 'noskoolz', this is quite small as the big boys are
using anything upto 85mm or more, but as a beginer these will give me some easier practice until my technique is good
enough that i can pump them to their speed limit.
They are a good fast wheel and centre set so this makes the truck ride like a slightly smaller truck
and are quite wide (40mm / 1 1/2" contact patch), so give got reliable traction.
I'm sure there will be alot of changes to come as there seems to be alot more talk about skumping lately,
my next upgrade will be a 'Carver CX' front truck, as this seems to be the best off the shelf truck at the moment, but the
future is bright, there could be things we have never seen just round the corner, so watch this space?
I will add more as i progress, so if it sound like something you might enjoy, get up set a board up and
get out there, this could be the next big thing in the skating world, the Pavedwave guys are skumping 'marathon' 12mile
trails, so keep your eyes out for bike paths aswell as hills when your out and about, or better still find a route that can
be measured and start timing yourself?
How ever you do it, its alot safer than bombing hills and you can still do it when there are none, so it
sort of changes things!
Have fun.
I have only been riding this style for a matter of months, so what i dont know far outways what is
on this page, so if you like the idea and want to know more check these guys out, they started it and are pushing the
boundaries further than anyone.

Now i'm getting somewhere, this is the best setup for me
i think. (bellow)
I've come to the conclusion that 'LONG' distance pumping is not what im good at, mostly
a fittness problem and lack of practice, but short distance yes.
So this is a 36" x 8 3/4"deck, 26" wheelbase (inside bolts to inside bolts), i'm now
using a Bennett 5.0 front truck and a Tracker RTS 109mm rear, with 76mm 77a pink gumballs.
You can see the wedging on the front truck is alot higher, this will stop wheel bite
and you also need it as these Bennetts really lean, they are the perfect pumping truck, i started with the 4.3 width, as its
a little easier at 1st, the rear truck is slightly narrower, i have found this helps my pump.
The wheels are the pre runner to the Abec11 pink 'Big-Zigs' they roll for ever, grab
some if you get a chance.
Try it, its great.
