Used Pilot SL ski wear pattern

This ski, with 2,222 miles, was ridden in both the 2009 & 2010 seasons in the UP of MI.

Not only was there heavy wear on the center of the keel, but excessive wear on the insides of the host bars. Note the insides are worn more than the bottom.

This wear pattern was inevitable! Just like dual runner rods, and the 2005 to present Polaris IQ skis, debris gets funneled through the channel, blasting away at all three surfaces.

Note how the rear of the rubber stop has collapsed, on the bottom, above the shim. The two larger pockets in the rear have no positive effect, only negative. (less mass = less support) You might think they reduce weight but the whole stop weighs only .2300 lb. Only the narrow center pocket serves a purpose, because it centers the shim.

To avoid the excessive wear of the Pilot SL skis use a single rod, on the inside, with a Ski Saver that completely covers both wear rod pockets.

Keep in mind dual runner rods/skis get their results because they have different profiles. The list below demonstrates how similar the profiles actually are.

Dual Runner Gaps between carbide:
Accu-Trac – 1 1/8"
Dooly – 7/8"
Duece Bars – 7/16" - The main reason for its function is the host bar is 15/16” wide.
Pilot SL – 15/16"
Polaris IQ ski – 1-1/8"
Slim Jim – 1-1/16"
Double-Down – 1-1/4"

The Precision ski gap is (4-1/2") and Simmons ski gap is (5-3/16") and yet they followed each other even with an 11/16" difference.

With all these similar products, it shouldn’t be long to reach the point of critical mass where darting will become widespread for them.
