Eric -- excellent to hear your endurance experiences carried over into this, thanks for comments on the site! Really opens up the possibilities when flatland like you've got is a big wide open LDP playing field. Having the healthy addiction helps eh?? Would be cool to see shots or vids of your rides in Lille!
I like the stickiness of Avilas with the lips shaved off, that would be similar but not exactly like flipping. Center of wheel would be pulled in a decent notch, cool to hear more of your riding impressions on this.
I did test out some of the Sidewinder trucks, IMO they're a really fun downhill carver, the ride is slower and surfy, CarveBoard-ish, they pump nicely, though a touch on the high side. For LDP I wouldn't mount them to match front and back, but put a stiffer truck in back, then you'd need serious riser for the rear. I tinkered with various setups but never quite got one that felt effortless and forward-powering (fast) enough for long flatland rides.
Happy pumpin' new year back to you, and welcome--

nelsonn, we're snowboarding tonight, i'll tell someone there to give that a shot and videotape 'em. ;-) i think you'd need a nose that tic-tacs, like the front couple feet of the board cut off at a circular angle and reattached into the board with tongue and groove, adding small bearings inside for the nose to swivel. or a board with hyper camber and ultralight, so you're actually able to bounce turn to turn. OR just get back on the chairlift at Whistler and board for 2-3 hours effortlessly before reaching the bottom of the hill....yeah...that sounds more like it.
btw saw your post in Trucks, i've got an extra pair of those Original cams/bushings in case you haven't found some yet.

Does anyone know if it's possible to pump a snowboard? Obviously you could pump if you were doing some downhill slalom thing, but what about flatland? Or uphill?
I figure it would be insanely hard, but I think cross country snowboarding would be a sweet alternitive to LDP in the winter.

Since I have the original German Seismics (before different baseplate angles were offered) I do wedge the rear to remove steering. I also add 1/2" riser to the front to increase leverage. Not enough is said about this latter method, imho, and it really can wake up a truck's action. I run ultra-light springs up front and two levels firmer in the rear.

@ Adam, thanks and one question: when you use Seismic trucks, do you have them with any sort of wedge front and rear?
Thanks

Don't discount Seismic Trucks for pumping. I get great results with mine. Just don't under-spring your trucks (i.e. do use heavier spring on the rear) and go with the slow-turning baseplate in back.

Heeey, another guy read the whole thread! :)
I have tried pumping on Holeys, and didn't like it toooo much. Just didn't feel like I could get my weight into the transitions.
The Carvers are indeed frighteningly high, but almost pump themselves. If you are, as you say, addicted, you will have to try these sooner or later. Take your medicine! :)
I've tried the slalom trucks, splitfire front, Tracker RTS rear. Very good. Very different feel from the Carvers, and pumps well going slow or fast.
The Randals are really not bad at all for carving, especially with a flexy deck. The 180s don't have too much of a low gear (slow), and the 150s don't have as much of a high gear (fast).
Bennetts appear to pump fairly well. And I'm having surprisingly good luck with Independent trucks, 169 with a slight wedge.

reversed Avilas

Hi everybody,
I'm new to this forum. First I'd like to thank all the contributors for their very precious advices. I learned a lot reading the 1367 posts.
I'm from Lille, north of France a few kilometers from the belgian border. The land is as flat as in the song of Jacques Brel "le plat pays" with quite a lot of ways for bicycles, not as much as in Belgium or Holland, but it is not so bad.
I started longboarding at the end of last summer and I discovered LDP at the same time thanks to the pavedwave website. It immediately interested me, first as a natural way of commuting. Second I like endurance, I'm also a marathon runner. I think I'm addicted to skumping now. My only board is a 44" pintail Lush Mako with Holey trucks. I wedged the front and dewedged the back with khiro shockpads. I replaced the front stock conical bushing by a white Khiro barel. Recently I moved the front truck to reduce the wheelbase to about 28". The board is much more dynamic with this shorter wheelbase but at the beginning, I had the strange feeling of energy lost as the front truck moved from one limit angle to the other one as if there was a mismatch between the wheelbase and the trucks hanger width. I ride on clear red Avilas which are quite wide. Today I tried to reverse the wheels so that the wider lip looks inside. This decreases the total width of a few centimeters. It feels like the pump is more fluid. It seems to keep the traction and smoothness, with an improved transfer of energy. Did anybody else experienced with reversed Avilas ?
I guess someday I'd like to try other trucks also. I'm a little bit afraid of the height needed with the CX. Did anybody has further comments about the RTR (I already read the description of James Peters on the pavedwave gear page)?
I also heard about sidewinder Gullwings. Is there a place where I could learn something about these rare trucks ?
Happy new pumping year
Eric

rear: traction == speed?

Hey James, thanks for your feedback on the rear.
Would you say it's the traction that's giving you the pop in the rear truck? I just about never run out of traction while pumping. Yet, when I did small wiggles on that PVD equipped foamcore, that board just launched! Didn't feel like it had anything to do with traction. Do you keep your rears tightened down for more return to center?
My sensation is that if I'm putting a TON of side-to-side traction demands on the rear, I'm giving up too much energy going out wide and coming back. More so at faster speeds. Usually have a high frequency low amplitude wiggle at cruising speed.
James, I was hoping to wait until Chaput's Fyre trucks came out, but now I'm poised over the "Buy" button at Asphaltplayground.com.
Oh, regarding pace, my runs are usually disrupted with sidewalk to road transitions, stop signs, potholes and cars. When the wind kicks in, I look down to see 7mph on the GPS. :( _Top speed_ is like 13mph. James, you're da man.

.. how far you dewedge the rear truck and as per your experience .. any benefits in having wider rear axle than front? .. sometimes i feel that i got faster others that i cannot get even going.
Many thanks for the info ....

I really prefer the traction from an offset or split-axle truck in the back. It's a marked difference in the potential forward propulsion you've got over a standard truck. Setups with standard rear trucks are fine for chillin, but for a bump up in performance the efficiencies of racing trucks are serious!!
The rear trucks of five current setups in my LDPs, in order from most to least used are
- SplitFire 107mm Rev1 w/dewedged Tracker baseplate
- SplitFire 107mm Rev2 w/dewedged Randal baseplate
- Tracker RT-S Offset
- Japanese GUS truck
- Carver C2 truck
Been running bushings in the 80a-90a range in the rear. Would like to try an offset Bennett, but it ain't in the current budget...
Deuces thats a damn nice average cruising speed if you're going against wind and uphills much of the time! Most of my runs are early morning before the wind picks up. Just like with surfing- the early mornings pay off in smoooth rides.

i'm green to pumping but i'm already adicted to ... i had the same question about the rear truck and i read as much i could find .. not much, except that it should be with hard duro bushing and the tigther the better.... i've been experimenting and so far it seems that my findings are correct. Peters webpage, Sk8kings, Steve Hopper from Insect and Dan Gesmer have been very helpful.
Front wedge about 20 degrees and rear its king pin almost facing down. I have Split 107 front and back - front with one spacer and rear as wider as possible. My board is a Insect City Bomber. I'm still experimenting, technique is also very important ...
Any help very much appreciated..

rear truck?

How important do y'all find the rear truck? I'd been really focused on the front truck, but have been pretty much ignoring the rear. That is, until I put Carvers back on my LDP.
The power cycle on the Carvers are in a VERY different spot than the splitfire 90mm + RTS 139mm combo I had been running.
I noticed a lot of rear wheel lift when standing still and tilting the board, so I loosened the rear truck and the propulsion seemed to drop quite a bit.
Also, I had the fortune of trying out someone's foamcore+PVD setup, and that thing took of if you even thought about pumping. Made my LDP setup seem SLOW by comparison. I'm starting to think that had more to do with the rear PVD than anything...
Strangely, on my low setup, an Earthwing Superglider with Indy 169s, I gotta keep both trucks super loose to make any power with the pump.
With all this, I'm thinking about getting a serious slalom rear truck, perhaps a splitfire 107mm.
Any thoughts?
Oh, I also got a Garmin GPS thingie. Looks like I'm very slow, about 9.5mph is my "fast" pace, combined kicking and pumping. Fighting wind or uphills with pure pump makes my feet hurt too much! Anyway, I'm amazed at James' pace with pure pumping, hitting 12mph? Wow.

This is the best explanation for novices that I've found: shapeshifter's howto
I do believe you need to create on www_silverfishlongboarding_com to view that link.
Shapeshifter's made other instructional posts on the pump. Search for user=shapeshifter and keywords=pumping for more goodness.
For learning, short wheelbase and super turny trucks help.
Do you know how to tictac? Feels very similar, except instead of picking the front up, you just use the truck's ability to tuuuuuurn.

yep, smallies worked. im back in bid-ness.
took about a 3 week hiatus from da pump, been working on a couple old school 24" GT BMX cruisers (for me and the missuz). pretty funny- two 30-somethings riding around on dirt bikes. fun as heck though. would like to build up an old 26" if I could find one.
gotta say, the weather has been perrfect for ldp in Sacramento the last couple days. Sunny, dry and cold. I am playing hookie tomorrow and going to hit the river bike trail (off limits to roller, but I'll take my chances). i love being able to "work from home." and bless the cell phone.

Rick, the pro splits are definately a nice bump up. I think it was 'relatively insignificant upgrade', but more accurately, they're an optimization for something like long distances where your turns aren't always required to be as precise and technical as for slalom. But you can always benefit from extra precision (imagine last-second squirrel dodging, dog lurching at you while owner holds them back by the leash, boulders on the shoulder at 35mph downhill...etc) but that's where I don't go up to a Rad or Gog, there are usually trade-offs at the high end, i.e., fragility for performance. So far the split pro is the highest performance truck I've tested on trails that's incredibly durable as well. I just keep my LDP and GS board fronts mounted with the randal-type baseplate, its easy to swap out the hangars/bushings! If someone were trying to save a few bucks, the earlier rev's are great. I use 107mm's + spacers, as the 90's seem a bit narrow for big wheelbase and longer pump cadence.

Thanks for the feedback. PSR, while the Fyre trucks look promising, my needs (desires) may not be satisfied by waiting… James, I read in a previous post that you didn’t think the new splitfire pro was LDP oriented. In your opinion is the addition of the spherical bearing a plus, a minus, or a wash for LDP? If it is a minus, which of the older versions was best suited to LDP?
Thanks again for the help!
