I have Marker dukes and my DIN is 6,but I would like to let a friend try them who uses a DIN of 4. Would it be too big a risk,or is there a way to get it lowered ,perhaps by a softer spring?
No, there's not. It is what it is. If you're friend's boot sole length is the same, he/she can pop them on for a few runs, but if they're small enough to be at DIN 4, they may or may not come out of them when needed. Your (and their) call. If you need to adjust the binding at a shop, if they'll do it at all, they'll have you sign off on it so they won't be liable for potential injury.
Definitely not possible, besides 6 is already too low, bindings shouldn't be set at the lowest (or highest) possible din setting, they should be set at least 2 or threes settings from the max or min setting. Out of curiosity who needs a 4 din? seems extremely low to me
I also just set a din of 4 for a 110lb girl who is a complete beginner the other day, you must have a very small friend.
Uh, no. As long as they are adjusted in the manufactures approved range they will perform as advertised. A din of 6 is a din of 6 on a duke or baron or Solly Z10 if they are functioning correctly.
Agreed, but the reason for purchasing a binding that is at least two DIN # above/below your DIN is in case your DIN # changes. e.g. skier goes from type II to type III or III+, or reaches age 50.
