tuning rockered skis

post #1 of 12
Thread Starter 

Any links to tuning rockered skis with "early rise"?

Since the idea of "contact points" is out the window.

And what about reverse sidecut (Rossi S7)?

you already know the answers really...

 

do you want reverse sidecut to catch or grab or edge at all? no so detune any edges that are going the wrong way.

 

I have found you can keep normal sidecut with rockered skis sharper than there non rockered counterparts as the tips and tails cant catch when they arent touching.

Tune where the sidecut is, don't tune (sharpen) the early taper areas of the ski. Wax the bases, scrape the wax, go ski. Done.

 

Keep in mind the whole point of rocker or reverse camber is so the ski will pivot and smear, don't screw that quality up by trying to put a race tune on the ski, you'll just end up with a ski that skis like a broken- bent- low performance- ski. Use more  base bevel if you want (think you need) sharp edges under foot... basically, if you need sharp edges at all switch skis. Skis like the S7 are fun to ski in mixed conditions, but no tune in the world will make them something they are not, on the other hand, an inappropriate (going for 'ice skate') tune will wreck the 'good' qualities. KISS.

Pay attention to the bases, keep them smooth and well waxed and structured appropriately. Fill any core shots under foot immediately. Rocked skis are slow for skating and polling on the flats so keeping the bases in good shape will help this.  Edges ... just check the base bevel initially (1 degree or more if  you want) and debur every few days.

OK, on my S7's (haven't skied yet).  Detune the rockered tips and tail back to where they turn into conventional camber.   Cambered ski underfoot: ?  1 degree base and how many degrees on side?

 

 Normally I will go 1 degree base and 2 degrees side should I keep this for the S7's ?

Pete, what i am taking from above advice is tune from where sidecut (on the S7) starts.

The reverse sidecuts fore and aft don't need to be sharp, since they don't engage

or release the turn on harder snow.  And i would be interested in angle combos

that others are using.  I would not think more than 2 degrees on the side would

be advisable or necessary.

Mine are sharp tip to tail. I use 1 base and 3 side(mostly because I have 3 deg guides).

BUMP.    Anyone know how to tune S7 rockers ?      Alpinord are you listening?  Without any real knowledge I would detune slighly the tips and tails down to where the rocker almost ends and then do the middle at 2 degrees.  Comments?

Do you mean 2 degrees of base bevel?

1 and 3 tip to tail.on both Rossignol S3 and Super S7. They hook up great and don't catch unexpectedly. Same tune i use on my race skis.  Way more control on run outs back to the lift. The skis will rail if you lean them way over, particularly the S3.

simpson, have you skied the S3's with both 1/2 and 1/3?  I've skied mine with the factory 1/2 a number of times and find they hold really well.  I, like you, tune all my skis at 1/3, but haven't changed the S3's yet.

 

Can you say you have A/B's them both ways, or just done 1/3 the whole time and like it?
