On pre-drilled roller skis, like the new Swix Triac Carbon Classic, one can choose pivot point placement by using different binding brands and models without drilling new holes. This is so because different bindings use different screw hole placements in relation to the pivot point.
Swix Triac Carbon Classic shall not, according to Swix, be mounted with NIS bindings, and there are no pre-drilled holes for NIS or any other mounting plate system. The way to choose binding position is by selecting different screw mounted bindings. There are two sets of pre-drilled toe piece holes (the three holes stemming from NN-75 bindings) in Triac Carbon Classic. By using the two sets of holes and the bindings Rottefella Rollerski and Salomon Prolink, one can have the pivot point circa 10, 25, 35 or 50 mm behind balance point. Rottefella Rollerski gives the 10 and 35 mm options, and Salomon Prolink the ones at 25 and 50 mm. I would probably choose Rottefella Rollerski in the foremost position rendering the pivot point 10 mm behind balance point. I don’t see any advantages in the 35 and 50 mm positions, only disadvantages, so it is a little strange that Swix didn’t drill the holes 10 mm further fore, permitting a balance point mounting with Rottefella Rollerski.
