Gbomb Brackets Information Update:

James first introduced me to the Gbomb brackets, after the first Ultraskate I did with him.  From the moment I stepped on them I immediately fell in love with them.  I saw so much potential in them in ways that at the time I did not fully understand.  At the time my goal was to create a hybrid board that was to be a full LDP board with the benefits of being lower for pushing.  In setting up for my second Ultraskate Mark graciously gave me a set of his brackets free with the condition that I use them for my next Ultraskate.  Over the next month I proceeded to dial his brackets combined with a Loaded Dervish deck as best that I could.  Being new too pumping I had to learn fast in terms of setup and feel.  James website has been an invaluable tool for learning.  He took all of the guess work out of trying to setup a good board.  The board minus the trucks were very similar to the Loaded Fathom board that Loaded and Mark are currently designing.  My deck was based on the same length as the Fathom so we proceeded just to call the deck the Fathom Proto.  The true Fathom was not designed to be a pumper deck.  From what I understand the deck will be a commuter board.

After skating with James on the 2nd Ultraskate I also learned that even though the Fathom proto was pump-able it wasn’t really ideal for any real length for multiple reasons.  One: the loaded deck proved to be too soft and even though the deck was fun to ride, there was a significant loss in power when pumping.  Two:  By having the truck essentially on top of the deck it created a pendulum effect on the board that again equated to loss in power for pumping.  Having learned this Mark offered to continue to work with me in order to try to get this board as close to LDP as possible.   Mark and I work for the next couple of months tirelessly going back and forth with different ideas and setups.  What I learned is that the closer you get the truck to the bottom of your foot the better the board will pump.  James had already proved this.  This creates a flaw in the whole dropped LDP idea.  As you pull the truck closer to the bottom of the deck you run into an unavoidable problem which is wheel bite.  Even if you have the truck lower but away from the foot you will still lose power and again touch upon the pendulum affect.  

After learning all this, again Mark and I just proceeded forward with still the idea of getting it as close to LDP as possible.  What came next was a complete redesign of the front bracket, and a less aggressive drop back bracket.  After many miles of testing it became very clear that a dropped design would most likely never become a Long Distance Pumper.  But after much riding and testing I discovered that another trade off took place.  What was gained, was leverage and control.  Enough so that I now could pump up extremely steep hills.  Having the deck at 4 inches instead of 4 ½.  it does have a lower center of gravity.  The trade off is that I have to exert much more energy to pump.  So much that I generally only pump about a mile or two at a time.  In comparison to other full pumpers the trade of is significant.

Even though the board was not the most efficient at pumping I still found myself gravitating towards the new design day after day.  At times I love pushing as well and the extra half inch proved to be just enough to be a bit more comfortable.  The board also became clear that it was extremely versatile.  I quickly adapted to this, and by having a lower center of gravity sliding and other tricks started to seem a bit easier.  That’s not to say you can’t do these things with a full pumper, because you can.

All of this simply started as a hobby to create something new.  It was thought that we would not continue past hobby status.  But Mark and I feel because of it uniqueness the board has merit, that perhaps others might enjoy.  I am aware that I do not have years of skating experience, and perhaps this does not qualify me to design a board. But that doesn’t change the fact that I have a tremendous amount of love for all forms of skating, primarily LDP.  This is all thanks to James Peters.  I hope that all see my love and passion for the sport, and how grateful I am to James.  

We are now trying to bring this board to light, and are still in the process of deck design.

This is how it stands currently:

There is the Loaded Fathom which Mark and Loaded are working in collaboration.

Mark currently sales a 24 inch Cambiar deck with a set of his normal 2 ½ inch wide brackets.  These are the same brackets that I used in the 2nd Ultraskate.

FUTURE:

Mark will sale a less aggressive drop bracket that brings the truck closer to the bottom of the deck.  This helps reduce the pendulum affect mentioned before.  It also creates a more rigid feel in the entire board.

A new redesign front bent bracket that will be better suited for pumping for a front Bennett truck.

A new 28 inch shape Pumper\Carver deck is still in the works.  It’s designed to capitalize on the new redesigned brackets.
.

This video was taken at Dorney Lake by Keith, it shows what the board will basically look like.  I packed it in my suitcase for travel.  It also shows the older back bracket.  The new one looks the same but has a less aggressive drop.

I hope this helps clear up some information.

Eric

so has anyone tried a 6.0 bennet with a 149 tracker rts on these? i tried one out with some randall paris hybrids and it pumped ok, but since it was someone elses garage boards setup it had harder bushings and not really setup for pumping ( still was able to though, a little tiring but doable) well anyways.. i have started the process of getting one and i was hoping for some info before i bought the trucks.


thanks!

Hey rodgon,

Funny you asked…I was just rolling around with them a good part of the day today.  For a top end speed 6.0's are kind of better.  And for sliding and pumping the 149’s don’t break away as fast but when they do there definitely more stable.  Makes sense for a wider truck.  But after a slide it was more difficult for me to get going again.  That being said they don’t turn as sharp.  Again makes sense for a wider truck.  But by the end of the day I was still back to my 5.0’s and 139’s.  I just like being able to turn on a dime.  With the brackets I like a blue orange barrel combo for the back truck.  It may seem loose, but keep de- wedging it ever so slightly on the back bracket to find the sweet spot.  It will give you a hint of stability that has a spingy-ness to it.

Marks brackets with a pumping setup still pumps pretty darn good.  You will be even lower to the ground then than my above setup.   With a 27 inch cut dervish at times I would scrap…..Being that low created a fearlessness in me very quickly.

His Cambiar deck is great as well, I have never tried them with a pumping setup.  But with Randal’s the brackets feel great.  The deck is truly dialed to work synergistically with the brackets.  

Here is an older short video clip of me pumping using his regular brackets on both front and back.

Hope this helps..

What's the difference between the new and old brackets?

Which brackets are currently on sale?

Are the brackets only available for sale?  If so, how much?  Length of time for delivery?

Thanks.

The difference between the original and the new curved brackets are the amount of drop.  His new design has less drop.  This is not to be confused with the new front bent bracket.  The bent bracket was designed to get the truck as close to the bottom of the front foot as possible while still avoiding wheel-foot bite.  It is not adjustable on the fly as with his other brackets, although you can still adjust the truck angle by de-wedging it.  I was able to get his original curved brackets to work with the new front bent bracket.  But in order to make this work and level the board I had to add thick back risers along with double black barrel bushings for the back truck.  This is what prompted the change for the less aggressive drop performance curved bracket.  I say performance because at the moment I received the prototype for this bracket I noticed a major increase in the way the overall board was responding.  Everything became far easier; the board became more rigid.  It effectively did away with the sagging pendulum effect I mentioned before.   Even though with the new brackets the deck is effectively higher off the ground, the increase in performance is significant.  Currently with the new brackets the deck sits at around 4 inches.



Currently Mark has in stock and sales his original “medium pusher” 20 mm dropped curved brackets.  He also has in stock and sales his Gbomb signature 24 inch Cambiar deck.  

He does sale the brackets separately, but it is my understanding that he prefers not too.  I know for a fact he is extremely passionate about providing an unforgettable skateboarding experience.  He spent a long time getting the Cambiar dialed just right for the brackets.  And believe me it shows, the moment you step on it you will see why.  It is an excellent pushing deck.  For him to only sell the brackets without a deck is like yin with no yang.  His fear is that people my go there own way in cutting a deck and not have a good experience with his brackets.      

The new “performance” dropped 15 mm curved brackets may go on sale as soon as December.  

The new front bent bracket will most likely come out before summer of 2009. (Maybe sooner)

The new 28 inch Pumping\Carving deck is yet to be determined for release.

For pricing feel free to contact him at his Website.  He is always stoked to meet new customers.

On a side note I’m truly grateful to be working with Mark.  I have a tremendous amount of respect for him as well.  He has been a true friend to me from day one, and he brings out the very best in me.  He is a class act in everyway.

Eric

Thanks for the info.

I'll probably wait till my next deck from Subsonic comes in before i make a move on another deck.  I should probably try to watch the expenses a little bit now...

By then, the second gen of the brackets shoudl be out, and the 28 inch pumper deck too.

Eric, some very cool evolutions, I'm stoked to see what comes of the pump brackets!!

I totallly hear you on the yin-yang deck thing.  I think anyone who wants to support Mark in this endeavor as an "early adopter" should pony up for his complete setup, the brackets PLUS the Cambiar deck that he designed.  One thing for sure is that Mark's deck fits the randal 150's perfectly with a huge assortment of wheel sizes, and zero chance of wheel bite.   That's because he and many others have tested that fun/egg shape deck to work all the kinks out.   Depending on your preferences, what you really end up with there might be a little too flexy for a long distance commuter, as Eric notes, but I think of the Cambiar deck as more of a perfectly symmetrical, springy and lively carving machine, very similar to the Dervish.   Yet the cool thing is with the brackets you can switch from a deep, soulful carving machine to a more stable carver in seconds, by just quickly dewedging the rear.

So if you do contact Mark, I agree, don't just ask for the brackets, get the whole deal.  I think it's inevitable people will tinker with the brackets on other boards, but the "tried and true" goes a very long way here.  It's really easy to set these up just a wee bit off, and end up face-planting because either your trucks were too wide or carved too deep and you didn't allow enough clearance on the corners of the deck.

That all said, I've been playing a bit again  Very Happy  

Mainly for three reasons.  I wanted to try something out that would 1. be uber-lightweight,  2.  have a kicktail, and  3.  be waterproof for the Northwest.

I just so happened to have an old Roe Foamcore to chop up.   It was one of his few "Torsion Core" decks, from some testing we did a couple years ago, trying to make a 44" LDP deck, but I compromised the deck toward the rear, after some longer pump sessions.   Basically, the rear end of the deck folded.  So I really didn't have any problem taking the jigsaw to it.  

The results are pretty sweet, although I'm probably going to bust even this length of deck as well.   It's almost all foam, and very little wood, very little fiberglass -- the sheet of Carbon is really what's giving the foamcore support.   I hope to commute on this deck a few times then comment more on the ride.    So far I've just taken it up and down the neighborhood and it does ride smooth.  

The stance is about the same width as Mark's Cambiar deck, the kicktail is just subtle enough to not get in the way, and has just the right pitch to "lock" you in.   I'm already pretty sure I'd rather have some harder red or green springs in that rear Seismic.

i put mine with a 5.0 bennet and a rts129mm.  in the back. the boards pumps like there is no tomorrow, its not as effective as my dedicated pumper ( galac with same trucks and heavy risers) at straight pumping BUT!!! its a very close second, given that and the fact that its very low to the ground to push just makes it a very very very good hybrid pushier pumper.

well taking away from the pumping aspect of it, i went ahead to a garage sessions and set up the deck with some mission 1 trucks and some 76mm superballs. the deck rode very stable, but the turning was bad, i had red khiros all around on it too. it made for a very nice garage board, but the stability i had at a front truck at 0 and the back dewedged  by 15 was a bit excessive. i reduced it to 10 in the back and added 10 to the front and it was a completely different ride.

i will have to say though, the board seems to feel alot better with smaller trucks. the mission 1a were around 190mm, and even though it felt good i think something along the lines of 139 or 150 would be way better all around.

which brings me to the question of the hour.

to the people that have ridden these bracket with the cambiar deck. what would you think of runnning 2 5.0 bennets for the trucks with some 88a bushings on them? ( abec 11 bushings) would that make the deck too uncomfortable for speed? because of the narrow trucks? ( in which you still get no bite at all) or would that be too small?


just out of curiosity,

Garage Bombing (Pump Brackets)

This is basically the same setup that I used in the Dorney video, the only difference is that I’m using the new 15 mm drop back bracket now that has more leverage and control.  Up until now my main focus with the hybrid had been longdistance skating and LDP.  Garage bombing is something new to me and I have only been about 4 – 5 times.   I knew that having a front Bennett made for very versatile riding.  By nature you want a loose front truck for pumping.  Over the last number of months I have just gotten used to it and grown extremely fond of it.  

The video was taken in the beginning of the night by my good friend Hanael (Many Thanks).  By the end of the night I was speed pumping quite aggressively most of the floors.  Having loose trucks didn’t seem to bother me.  In fact I prefer it. In retrospect when I try to ride what would be considered a garage board I am unable to do so and tend to fall off the board because I am not used to having tighter trucks.

Visually the board looks small but with a 28 inch deck the wheel base is that of about a normal size pumper setup.  Nevertheless I feel very comfortable on it and feel very aggressive with it.  I was able to pump up the floors pretty easily and that was a first for me.  I was told the average speed in the garage was in the mid to low 20 mph.  I definitely could go faster.   But maybe I should start thinking about a helmet……

Here is some additional footage of some bank skating.  Same setup, no changes - 5.0’s and 139’s.

Hey Barry thanks man…I appreciate the kind words.  But honestly Mark has just been amazing to me.  It’s really all him on the design.  I’m just gratefully to be friends with him and skating his brackets.  It’s crazy how we hooked up through JP. Thanks again man…

Speaking of friends….

I can’t wait to hit up Dorney again with you.  I will do my best to bringeth the SUN…..

Sweet Dude Wink

I hope we get a spell of calm dry weather when you come over. It would be good to pump and shred a whole day away at Dorney with you again.

Take care,
Barry Wink

ive got mine setup with 5.0 and 75a tarantula wheels and it rides very nice,

the effect of the brackets make it feel more like a 4,3 or just a smaller truck though. might have to try thee 6.0s to make sure ^_^
