Default Nitro Magnum sensitive to bumps in base below thread inserts?

No, a Nitro board should be as good quality as a Burton board in general

Do you have dimples under all 8 inserts, or only the 4
that have bolts in them?


Only the ones where bolts are in. Now it are 8 spots in total because I
moved the position of both bindings...

Either way, the dimples will not effect your ride very much.


But still, it's not normal...


If it's a more than 1mm deep (I interpret your use of "few mm" to be
2-3), yes that is not normal. However, it is not uncommon to have a 4
minor dimples where the binding is. For the dimples to remain there
after you move the binding off the inserts, my initial impression that
you overtightened the bolts despite your assertion that you did not,
the only other possible explanation would be that the materials used
in the core were some how defective - and if that were to happen I
would suspect it would occur to a large number of boards (i.e. a bad
batch phenomenon). Another thing that happens is boards bases can be
slightly concave or convex... there are natural fluctuations in the
manufacturing and while not "defective" (and exchangable) they are
also not "ideal".

As for the edges, the edge material is the industry
standard 48 Rockwell steel, so I don't think there is a difference there
either (I could be wrong) perhaps each came with a different base/side
bevels (which do affect how long the edges say sharp).


Normal 90 degrees now (and the first months too). I tried 89 degrees
once, but then I could not get the board to turn without using too much
force for my feeling. I still do not understand why the impact on the
riding was that huge.


89 (I'm assuming that means you side bevel is 1* larger than your base
bevel) degree will dull quicker than 90 degrees. Are you still
skidding you board when you turn? (if not your trail would be a thin
line behind you). If you are skidding your turns a board with a 89
degree edge will "bite" into the snow a lot more and "resist" you more
I think.

Good luck!
