You can take a look at this link: http://www.skierspeak.com/store/scripts/openExtra.asp?extra=7

I hope this helps...

Thanks although I have had 5 pairs of ski's radial tuned by skiers peak.

What do you know then? It sounds interesting.

 I've never seen that tune, but I've seen quite a few with less base bevel at the tips.
post #6 of 18

The radial tune typically has 0.75 to 1.0 degree base bevel on the shovel and tail, and 0.5 under the binding, with a standard 3.0 edge bevel for racing.  This allows for easier turn initiation (don't need to be as precise) yet still the quickness of of 0.5 degree base bevel.  The radial is being used on both slalom and GS instead of the typical slalom (0.5 base, 3.0 edge) and GS (1.0 base and 3.0 edge) setup.

For base edge maintenance you can use a 1.0 degree tool and polishing/surgical stone, or free hand it.

Thanks, never seen that version of base bevel before, seen it on the sides, but never on the base.
Will give it a go next season on my old volants.

 Stockli has been doing this for years and years - nothing new.

Speaking of this -- and this may be a novice question -- but what are the exact (or approximate) demarcations for changing the file angle along the ski base? Is there a science to it, or do people just kind of eyeball what's considered front/middle/back?

Thanks,

When I was maintaining the radial tune on my Stocklis I would go with the .5 base bevel under the length of the binding.

I decided though that it was more trouble than it was worth and I haven't noticed any decrease in edge hold using a 1 degree for the entire length of the edge.

Question for the radial tune success stories:

Have you skied a ski that you've thought was really rigid underfoot (underbinding) and did the radial tune change that feel?

On a GS ski the radial tune will give you a feeling or more "rigidity" or better hook-up with out making it harder to ski.

I don't ski slalom so I can only speak theoretically - a radial tune on a slalom ski it should feel just as "rigid", just a little more forgiving.

Funny...this is pretty much what we used to do, long ago, by hand with just a file. In the early '80's, a Dynastar tech rep did a tuning clinic for us at Breckenridge, showing us to hold the file with our thumbs over the ski edges to prevent the file from bending for flat filing, but to hold it at the ends to bend it for a few strokes on the forebody and tail of the ski. It was all done by hand and eyeball, but the effect was to increase the base edge bevel on the tips and tails. He recommended it instead of the usual "detuning" of the tips and tails that most tuners did. With this tune, the ski was still easy to turn, but with edges sharp tip to tail, it would hold much better than a "detuned" ski once tipped on edge.

Today, I question the virtue of this tune on many of our shorter skis. All skis twist at least a bit, which will have the effect of decreasing the edge angle--and increasing the effective base bevel--at the tip and tail anyway. Increasing that further with a "radial tune" seems counterproductive, at least for a highly skilled skier and a race ski. Surely, though, it will still make a skie easier to pivot, and more forgiving for less-skilled skiers. And it might be worth considering on a speed event ski....

I'll stick with my minimal (0.5) base edge bevel tip-to-tail. I like my skis to feel "edgy."

Best regards,
Bob

Here is my take on it and what ski's I have with a radial tune.

Fischer SL hole ski "54"- The tune is awesome ski is very quick and easy to initiate and release the turn, Unlike the 1 degree base bevel it had before.
Blizzard WC GS- I didn't notice a major difference between this and the 1 degree base bevel except it seems to hold better on ice.

Blizzard GSR-  The same as the Fischer

Volkl Racetiger SL- Same as the Fischer

I know quite a few people who have the radial tune and like it alot.

thanks for the feedback. might give this a try on my VR SLs

Is this what Montana touts on its robotic tuning machines? Any opinions on the robotic tuners from Montana and Wintersteiger that do a grind and then an edge tune? 
post #17 of 18
Have only seen the robotic base grinder. Holds skis with vacuum clamps, then moves it over the stone. Computerized settings to dress the stone for different structures. It can bevel the base too - for snowboards.
I know that the computer "upgrade" for that thing was almost $20k and the stones are about $5k.

Here's a few comments on the "new" radial tuning from Montana.
From the Montana website and their Montana News, 3/08:

(note: Does Epic have the worst text editor ever?? It sometimes acts in bizarre ways like it did here. It took forever to just try and get this pieced together)


Philippe Roux: ex worldcup downhiller and owner of Philippe Roux

Sports in Verbier, Switzerland

“During the winter season I go skiing 3 to 4 times per week to test

different types of our rental fleet. Since we have had our MONTANA

Saphir with the radial tuning I can feel a much better turning capacity

together with easier handling. I can actually feel my skis and they

react like my race skis used to and those were prepared elaborately

by hand by my ski man according to my needs. Because of the very

positive feedbacks all our skis and boards are prepared with radial

tuning. It is an investment to the satisfaction of our clients and it has

already paid off.”

Andrea Zinsli: Former Swiss Worldcup Slalom athlete

 “I have tested the Radial Tuning at large and it is awesome. The

radial tuned skis are extremely smooth to ride, steering is easy and

safe. The edge grip, in particular under the bindings is fantastic.

It is easy to control the outer edge, all in all an outright quiet and

stable handling is guaranteed.”

Mike von Grünigen: Former Worldcup champion

"One of my tasks in the race department, among marketing,

developing and testing material is the continuous search of new

technologies. In the further development of our products I was able

to know Montana’s Radial Tuning and I have done a lot of tests on

different models, all prepared with Radial Tuning. The skis are

extremely good to turn, react more accurate and receive a balanced

and fluent dynamic. The results of the tests have completely

convinced me: all my test and racing skis are going to be prepared

with Radial Tuning from now on.”

In the continuous search of the

optimal ski preparation

MONTANA works very close with

well-known specialists of the ski

and snowboard Worldcup. Out

of one of those connections

MONTANA developed the Radial

Tuning which was only used for

racing in the beginning.

Doing different test rides with

different skiers we found out

that not only the racers can

profit from Radial Tuning.

Because of this dynamically

adapted base edge beveling

system, the riding comfort is very

harmonic and less aggressive.

The turning capacity of the ski or

board is increased and the grip

on icy slopes is much better

under the binding. Speaking

from experience this is a big plus

for active safety along with

optimized riding properties.

Thus an initiated turn can be

interrupted any time now even

with full speed without risking a

fall with bad injuries.
 

How do we get radial tuning

onto skis or boards?

With the ordinary tuning the

base edge is being ground in the

same angle over the whole ski

length.

With Radial Tuning however we

get different angles; that means

the angle gets wider towards the

end and tip of the ski or snowboard.

Based on a program the computer

calculates the optimal tuning

parameter for the ski.

After that the ski is guided over

two grinding rings by pressure

curve controlled pneumatic

cylinders, so the ski is getting

worked from underneath. The

result is an optimal angle adapted

to the ski’s geometry and

radius with smooth transitions.

The MONTANA Radial Tuning is

an option available and can be

modified in all the service installations

of the new machine

generation.
