The abbreviation EPF stands for "Extended Powder Frame". The basic construction of the Marker Duke has remained the same, but the frame and the mounting points have been visibly widened. The minimum ski width with which the Duke EPF can be used is only 88 mm, but especially wide freeride skis with a center width of 115 mm and more should benefit from the increase in width. This shows that this is a strongly downhill-oriented binding that is suitable for ascents.
Since March 2012, the binding has collected a good 15 freeride days in test operation, mostly in terrain accessed by lifts, although some ascents up to 1000 meters in altitude were also included in the program. The downhill-oriented freeride days went to our complete satisfaction. The touring days, on the other hand, went as expected with a lot of uphill sweat with the heavy binding on our feet.
Positives
The most noticeable change in the Duke EPF compared to the previous models, apart from the design, is the increased width. Another positive aspect is the more comfortable operation of the climbing aids. A gentle push or pull of the pole and you are in the desired step of the climbing aid. The climbing aid can be operated quickly with the tip of the pole and then with the pole plate to the highest climbing level. You can return just as quickly and easily using the pole plate.
