put a longer grade 8 kingpin and use two bottom blacks instead of tops. bones hardcore hard duro bottoms work good too.

Don..You can make Indys work for luge. John and I started on Indys and Lee Dansie used them for a few years at the Xgames races. I wouldn't fuss around with them very much as Randal RII 180s are inexpensive and a much better truck for luge. You could use wedge risers to take steering out of the back truck if you are looking for more stability. Run the back truck tighter than the front.

Indy 215's good for luge too?

Hey Dave. Do you have any experience with the independent 215 truck
for streetluge? Its what I have, I changed out the orange bushings
for hard black ones (had to shave to top bushing for that to work).
Any advise to make them more stable/fast?

Size Matters?

It's all in the body Fredrik. Wheels do not have a "Top Speed"...you do!
KRIMES said something funny one time "Big wheels are so '05".... or something similar. hahah
This is the way I look at it....If it doesn't matter on a streetluge, it really doesn't matter for DH skateboarding. Even on a streetluge, aerodynamic forces dominate the top speed and acceleration equations. Big wheels never showed an advantage in numerous test runs. Fancy ceramic bearings or minimizer bearings never showed an advantage either. I think some of the really big wheels (97/101) are actually slower. 83mm is as big as I ever raced.
70mm to 85mm seems to be the sweet spot. Bearing rotation speed (rpm) is not a factor since the bearings can be used at much higher speed than a skate or luge will ever take them to. Bearing friction increase as it relates to increased wheel rpm is a non-issue as well.
Ride what feels right to you in terms of grip and smoothness and forget about the size.
Now if the road is really rough and bumpy or you have to cross some railroad tracks at speed....the 97's might be the ticket ;)

The 160mm DH trucks have a 35 degree baseplate and a more restrictive bushing seat area, whereas the RII 180 has a 50 degree base and an open bushing seat area. The DH's are really slow turning and stable...that's the way Randal wanted them. The 180's turn much quicker and were designed more as a carving truck. Putting a 180 hanger on a 35 degree DH base is a popular "go fast" setup.
Great article on bearings. I run the inexpensive bearings such as Pleasure Tool and have no problems with them. ABEC 3,5,7 whatever....they all work the same to me. If bearings mattered, racers would all be on fancy ABEC9 Ceramics. Save your money!

Thanks for the test reports Toby and AJ. I'm pretty happy with my Skyrunner. I have a 4-Fight LT also and it seems to have a bit less thickness of foam and a plastic (polycarbonate?) shell.

Smaller wheel»»»»smaller speed...think this way: your limit, beside aerodynamics and road you go into, is the rotation of the bearing...Every bearing has its rotation limit ( rev/s )!So, for the same number of revolutions, a wheel with a bigger diameter or radius will travel a bigger distance than a smaller one...So keep on 83 mm fly or bigger!!! Take a look at -- http://www.minibearings.com.au/hobby/skate.html#2 ----- for the rev/s of any ABEC ratings...and more interesting stuff

Wheels size v/s Speed

I think this has been asked before but..
I´m thinking of testing some smaller wheels than the 83mm fly and I´d like to hear your teories.
Do you think you can reach a higher top speed with a bigger wheel?
Does a smaller wheels stops to accelerate at a certain point?
Is there really a top speed for a wheel or is´nt it your body v/s the air that stops the acceleration?
Cheers!

SkyRunner Tested: Life-Saver

Many of the downhillers hear in Quebec ride Icaro helmets, and I would like to second Tommy's rating on the Skyrunner. I fell twice on this helmet last summer; the first fall was without impact as i tumbled down a run in the laurentians, I scraped the Visor over a long distance and it did not shatter or break, luckily i had replacement parts and the paint on my chin was only slightly chipped off without effecting the fiber beneath. The second time i fell on it last summer was its last, there was a good impact over the back of my head and the impact broke all the way through the fibers. I had no injuries to my head or upper spine ( my lower back on the otherhand...wish i wore back-protection vest)
No helmet is made to last more than one impact!
I am definately purchasing another Icaro in 2007, not too sure if i should stick with the skyrunner and move onto the 4flight series
Does anyone have a Review for the Charly No Limit helmets

Hello there David...im now making my own DH board (skate), from a flat piece of birch, and i´ve been questioning some about DH trucks! Im gonna mount the trucks drop thru but i just dont know wich trucks...from the esthetical point of view, i prefer the randal 180´s, they look better, they are larger wich from a cinetics view, increases turning ability!
But i think most people in DH uses the randal DH...are they realy much stable than the 180´s?I know that there are also some in standar 180´s( no baseplate changes etc)..what´s your opinion abut this!!
I put this link in the Bearing page... (http://www.minibearings.com.au/hobby/skate.html#2)
Give a look and tell me what you think!
Are we being mistaken on buying ceramics and ABec 11´s???
Thanks..apreciated!
Bye

Tommy tested his Skyrunner in Åre last summer. Cracked the shell and got a concussion. The helmet helped a lot.

Benny..nice to meet you on Sunday. Glad you are getting some great runs at GMR while you are down here. Keep it on the road so we can send you back to Canada in one piece!
Yep JBH, I have an 'Icaro Sky Runner'.
Pros: Lightweight, great visibility, great visor, good hearing, aerodynamic. Cons: Crappy chinstrap latch, fragile, $$$$$
Protection : I think of mine like a full-face skate park or bicycle helmet. No DOT or Snell ratings. It has a European rating for hangliding/aerosports. I have yet to see one really "tested" on the hill.
Also check out the 'Charly No Limit'

David, mind if I ask what kind of helmet you normally wear? Most of the photos I've seen (e.g., below) show you in some sort of white helmet with a very large, clear face shield. Is it custom made, or is it a stock motorcycle helmet of some sort?

Dave,
Just recently found your site and I'm loving your speedboards! Where can I get them, how much, what colors etc? Also, if I may, what kind of fullface helmets do most of the speedsters use? Is it a modified street or moto-x helmet? Thanks.

Hey Brent..Come out to the Badlands on Sunday for some outlaw DH! I'm not riding on Saturday, but you can probably find a few guys at GMR on Saturday morning.
It has been a pleasure riding with you thru the years! Going back to MI as one of the worlds best DH skate/streetluge riders is pretty cool. Winning an XGames Gold and a World Championship in streetluge were just a glimpse at your potential and talent in the downhill world.
See you on Sunday!
