Frequently asked questions
Why split this from /outdoor?
Bike, running, golf, and ski tools are used in a different workflow than hiking, fishing, and camping prep. The old /outdoor links remain compatible.
Can I use the ski DIN result directly?
No. The DIN value is a reference calculation. Binding adjustment should follow a qualified shop, gear manuals, and physical checks.
Is calculation data sent to the server?
No. Inputs are calculated in the browser only.
