Not Carveboard carveboards

[BluegrassSurfer]

Looks like the new Matrix hangers with the 18" axles and the threaded insert added to the bracket installed on your late model Comp 16 deck is what's going to get you an adjustable inside spring setting on a wide axle.

The new 18" wides are supposed to have adjustment nuts on the inside positions of the top truck/bracket. That's what I'm counting on. Will rig the Comp 16 deck first. Next, I want to try them on Gen I & II Razor decks.

Plan to try some 16" GI spring bionics on a Gen I Razor deck also.

Still haven't rigged a Gen I Blade deck with 18" Meltdown axles. Been planning to do that for almost a year now.

The new 18" wides are supposed to have adjustment nuts on the inside positions.

I zoomed in on the MBS carveboard picture with the 18" Matrix trucks and it looks like there are four holes in the deck and the underside of the hanger right where they should be for the inside and outside positions.

It will be interesting to see if the springs stay in a hard carve on the inside position adjusted to the loosest point. I think that's what was happening when people landed a jump off center and had to carve to correct. The combination of the hard angled impact and the hard carve caused the spring to pull away from the top hat and pop out because the bracket could be tilted to an angle larger than the length of the spring could span from top hat to top hat.

I think that is why MBS stopped making the inside position avialable. For off-road riding I think people also found that the inside setting was to loose with any adjustment or shock type.

Will the MBS carveboard be able to carve like this if you wanted it to without the springs popping out?


OldnB - do you know what the difference is in the dimension from the bottom of the deck to the centerline of the axle between the Carveboard carveboard and the MBS carveboard?

I rigged my Rennegade with the standard matrix trucks (15.5") with tophats/springs on the inside position (no adjustabilitiy). Very loose but low tip angles made it ride high. Nonetheless never lost any springs or had problems with serious permanent spring compression.

With 20s and no eggs (permanent outside settings) it was loose enough to carve. The leverage of 20" axles permanently compressed the springs within 6 mos and the condition you described above happened (front spring popped out midway down a carving run). Got very loose very fast.

That gave me an idea. I rigged the 20s with no eggs or springs up front and red eggs with springs in rear. Radical ride that was very responsive. Almost no significant permanent rear spring compression. Front springs are the springs that take the real punishment in hard-lean carving.

But I had to keep playing and added orange rear and yellow front with new springs to minimize spring compression. Increased speed significantly and stiffened carve which led to swinging too wide, hitting a curb, and bending the front axle.

I plan to use inside settings only with the 18" Matrix Wides, maybe yellows up front maybe none. Maybe yellows in rear with yellows up front. Maybe reds or oranges rear and no eggs but springs up front. Tension adjustment bolt for "minor adjustments/fine tuning." Should keep me experimenting until December.

Well my recent rigs (even the 20s before permanent compression) don't have any problems doing what is being done in your carveboard picture. I will be using the Wide Matrix for my decks. Their (MBS) carve board deck is to narrow for me. I like 10" wide for extra lean leverage.

I'm fairly confident I can minimize spring over-compression on the 18" Wides with adjustable inside settings. But that's what I want to find out.

Basically I think the problem with springs popping out is more related to outside spring position combined with permanent spring compression.

Most MB riders set their springs outside because inside is very loose and bad for speed wobble. And there is no tension adjustment on the inside except for eggs.

Have you seen this no springs at all set up a UK guy is doing? I don't know if it is good for carving but it is an interesting idea.

Funny how GI has gone to a spring/shock combination from their all elastomer truck and this guy is going from a sprin/shock combination to an all elastomer set up.

Yeah ... saw that. Looks interesting.

My guess is they will have shortcomings similar to the GI torsion cubes -- too much play in center and poor return to center.

Haven't ridden GI torsion cubes/bionics, this is just the complaint I have heard other MB riders make. Seems logical that it would be a problem.
