Longer, shorter radius ski vs. shorter, longer radius ski

post #1 of 6
Thread Starter 

I'm curious about something.  I've seen the specs for two kinds of DH skis:  Fischer RC4, 211cm, R=45m; and Atomic 217cm, R=40m.  Does this mean one would expect to be able to make tighter turns without skidding on the 217's, because they have a smaller radius, even though they are longer than the 211's?  Just wondering confused.gif

In a word, yes.  Will you be able to tell while making turns the size of Texas?  No.  cool.gif

Turn radius: when the skis are tipped to the same degree, the shorter turn radius skis will be cutting a smaller arc, eg, fully inclined just before boot out will let you make a smaller turn at full speed on the 40 m ski than on the 45 m ski.

 

Length: The longer the length, the more spread out your weight and turning forces are. If your are too light and the surface hard, you may not have enough down-force to make a longer ski dig in and hold the line. On the other hand, on a platform of snow with a little give to it, the longer ski will let you turn harder before the snow gives way.

It sounds like the Atomic is an older generation spec ski while teh Fischer is more current.  With speed skis some of the newer designs are more manageable and can provide better turn in despite an ostensibly larger TR.  This is quite noticeable in the Atomic range going form teh older metallic top sheet to teh Aerospeed 2. SR55 is a good source of information on these.

One more thing, two actually, all else being equal (it never is) the shorter turn radius will be easier to cleanly engage the tip, but the longer turn radius will allow greater speed around the same corner assuming you have no problem getting the ski engaged.
