i had revenge trucks for about a week and returned them becuase i couldn't get used to the inverted turning. i was used to indies where if you leaned left you went left and if you leaned right you wet right, i couldn;t handle that being backwards. do holey trucks and randal trucks turn like revenge trucks do? (not in performance, but in direction?)

geezer, have you measured the stock bennet axles?
did I just get lucky with >5/16"
or are they all like this?
btw, for non-cast in axles, what do they use during casting, a fiberglass rod?

My max OD of 7.95mm is .3129", and my minimum is 7.90mm, which is .311". Normally I deal in .001" increments, like most engineer and machinist types. .05mm is about .002", which is a pretty big chunk when you're setting bearing to shaft tolerance.
Typically you want .002" clearance for a slip fit on a shaft, particularly when you're potrntially dealing with end-users who'll let a bearing rust in place.

8.001mm axles

Just to give a relative insight into whats being mentioned over the past few posts. 0.001mm (otherwise known as 1 micron) is extremely hard to obtain. Thats getting into Rockin Ron territory.
The average human hair measures around 0.07mm or close enough to 3 thou in seppo talk. 0.001mm means you'd have to divide your hair into 70!!! To maintain this tolerance you need to maintain a constant temperature. If you were to measure your axle in the morning @ 7.98mm and leave it in the sun by lunch time it's possible to measure 8.001mm. Obviously why geezer shoots for 7.95 to make it easy to install and remove bearings.

Actual axle sizes

Supposedly, conventional trucks have 5/16" axles. Assuming the tolerance is +0.000, -0.000, which is impossible, the axle would be .3125" in diameter. Using the same metrics, an 8mm axle would be 8.00mm in diameter. For those who must convert, that's .315".
I've measured a lot of axles in the process of converting hundreds and hundreds of trucks to precision axles, and typically, I see Trackers, Indys, and Randals coming in at about .308 or a bit bigger.
My precision axles that I had run at a screw machine and centerless grinding shop that does a lot of high-end engine hardware, like studs and rod bolts, measure 7.95mm OD +0.00, -0.05.
That equates to almost exactly 5/16".
Ultimately, if the hanger and nut faces are parallel and the axle is straight, the diameter is the least important part of the equation. Grip comes from alignment and rigidity, not a number.

Yes, Landy/Bear offers a version of their Grizzly with 8mm axles. The Crail Speed/DH truck also has "over-sized" axles.

i see solidskate list the grizzly as 8mm, can someone confirm this?
http://www.landyachtz.com/D27.cfm?PID=285
I recent got a bennett vector
I think the axle dia is > than 5/16"
i couldn't measure, busted my caliper
my facing tool (5/16" pilot hole) won't fit..
5/16"=7.9375mm = 0.3125"
someone also told me the crail axle is 'oversized' too.

Evo truck choice

Evanc, I'd second that opinion on Bear trucks (although Paris, Holey, and Randal also come to mind) for your Evo. Select your bushings carefully, they're usually to main culprit in Wobs. Other things, like loose mounting bolts, not-quite-the-right-angle wedges, worn pivot cups, etc, all can contribute to cause wobs. Seismics are pretty stable, once pick the spring kit, and take the time to dial it in, and their turning manuverability is totally consistent, plus they stop turning (like Revenge or PVD's), so wheel rub can be eliminated. One unique feature is that the springs can be adjusted individually at each corner; So, if you need more tension under just the rear heel, that's very do-able, or if you need that front toeside to initiate a little quicker, again very easily done with the set-screw's adjustment.
The one downside is in how quickly the springs rebound (it's also a cool thing for quick-reaction turns or pumping). They won't cause wobs, per say, but Your reaction to them might. It takes a bit to adjust to them for most riders. Since you slide, that's something I'm not very comfortable doing with Seismics while on rougher tar (they can 'hop'), I'm saying you'd probably be better off with one of the 'Randal' style trucks. I've run my Seismics up well over 50 mph, but have gone faster (60) on Randals.

Yeah, gullwing is now owned by Sector 9, and you can't purchase Sidewinders (V2) anywhere. You have to buy a complete sidewinder deck. You can, however, buy V1 sidewinders from OldSchoolskates.com. The trucks aren't as "high tech" as the V2s, but they are sidewinders.

I am riding Bear trucks with my Evo and they are pretty excellent for carving. I haven't ever ridden seismic trucks before but I think that something along the lines of Randall R2's would probably be better if you are concerned about speed wobble. The Bear trucks (seemingly similar to the R2's) are pretty good too. If you are traveling at any speed while carving, go with the R2's or Bear trucks. That style of truck is known for their stability/maneuverability.

i am currently riding indies on my landyachtz evo and i have a minor problem with speed wobbles and control at high speeds. i heard that seismics virtually eliminate speed wobbles, does anyone reccomend seismics for a controllably fast, yet okay carving truck versus indies?

Hey, does anyone have any opinion on using Bear trucks as downhill racing trucks? They look just about the same as Randall 2's aside from the beefed up axle. I just got a set a few weeks ago and have taken them down a few small hills locally. So far I'm quite pleased with them they seem to be smoother than the R2's has anyone had much experience with them?

about 8 months ago, I saw someone pick up a pair from a skate shop (Val Surf) in Pasadena Ca. I talked to him and he said that he had been working on it for a while and it took him maybe 3 months to actually get them. I tried special ordering a set myself but they never got back to me about them. I am under the impression that they maybe have an exclusive deal with Sector9... and they don't seem to be very eager to let them out without selling you a deck too.

foggy, as far as I know you can't get them separately.
maybe you can try contacting gullwing,
I tried one guy's S9 sidewinder complete with a flush drop, i would recommend that one.
I been digging mine, put on some grippy 75a gumballs, low speed carving fun.
I took it to higher speed, but the truck gets kind of squirrely (but still way better than an exkate), gonna stick with R2's for high speed carving.

&16.95 british lb's or whatever, each? isn't it like 2.5 dollars per lb,or at least 2:1 ? that's like more than 30 bucks each, maybe. That wouldn't even be to bad if they're straight 7.99 mm axles, 95 a bushings might be durable but ,to tight. what else, i guess if i was in england i'd give them a try. I guess it's easy to copy a modified version of an existing successful product.

speaking of randal copies,
these UB trucks look like they are just slightly different than Randal.
"Imagine a Randal 180mm truck with a polished chrome finish and you have the UB 180mm longboard truck, Urban Blue have taken the Randal truck, tweaked it slightly and reproduce the classic longboard truck for half the price !"

that's too bad man. but you do what you gotta do...
recently i have had the craving to mod a set of randals i have for slalom or downhill or something. maybe bearings or ball pivots....
i imagine you machine your ball pivots and stuff, but is there a place to buy them?
and random question here--do you have a set of offset arms hanging around? or anyone else? i might take an old dh hanger, cut it down, offset the arms and through in some bearings or something

herbn, you are mistaking my "!" for excitement.
I don't get excited about trucks I can't ride over 20mph
It's more like, "OMG, it's a exact copy!!"
I came across this surfing the net.
I am not involved with the company, I think the owner is out of Marin, there is a retail shop on University ave in Berkeley. G2 is Boardsports' in house brand.
The only time I have being involved in trucks order is the Japanese GUS.
I wonder what Mr Randal have to say about this...

how can a total copy/rip off of randal not be designed for 20+, what's different? are they really such cheap sh1t alloy ,sideloads at speed?(they don't even say "turning at speed")can people really just take a truck and grind off the name and cast copies,whose getting excited about this,is "hc" involved in the company,i think he's a regular poster here, i kind of doubt he's making the trucks,involved with that mail order?,but... looks like a bit of misplaced enthusiasm. Here i'm a bit annoyed with tracker for going to the 50 degree geometry on their version of the randal,at least it looks like an original casting ,gullwing,and ah who else 50,50,50, a low profile 45 might be very cool and at least it would be different.my $.02
