2. Rottefella offers four different Power Tubes, which are selected based on a color code:
White: extra soft
Green: soft
Blue: medium
Red: hard
Rottefella recommends white or green for small boots (25.5 mondo and smaller), and green or blue for large boots (26.0 mondo and larger). Garmont Prophet boots have the recommended binding size stamped on the boot shell. Indicated as NTN-S for boot sizes 25-25.5 and NTN-L for boot sizes 26-31.5. The bindings (small and large size) are sold with these Power Tube options as standard. The red Power Tube is for skiers who prefer hard springs.
3. Release Settings Rottefella recommends dividing skiers into three groups:
Beginner: Skis conservatively/low speed. Set value one below scale.
Average: Skis moderately/variety of speed. Set value according to scale.
Expert: Skis aggressively/high speed. Set value one above scale.
Note: If skiers age is above 50 years, set value one below scale.
4. Adjustment of Power Tubes Adjust Power Tubes by turning them to the correct setting, using the printed scale from 1-5 on the Power Tubes as reference. See NTN technical manual for details regarding correct adjustment.
