This should increase control of the bike-sledge combination during hard decelerations instead of the current instability due to the sledges lack of direction control.
Just my $.02 thinking out loud.
Best of luck to you Sjaak.
+1 on the skis. And directional capability a must.
with a rope, when he hits soft snow or a ridge, or anything that brings his bike to a sudden stop and that sledge with all the momentum of its weight in fuel and supplies is going to hit his bike pretty good.
