Scarpa NTN Power Tube
Where to Buy
Here's what other sites are saying:
Choose the right color Scarpa (Rottefella) NTN Power Tubes to add or reduce tension, or to just replace your NTN Binding's spring cartridges. The micro-adjustable tubes are color-coordinated to correspond to different levels of spring resistance--so you can achieve the level of stiffness you need to carve up the mountain the way you want.
The NTN Freeride has a lateral release function, in addition to multiple Power Tube options, allowing adjustment of the forward flex to skier preference. Recommended power tube selection depends on skier’s weight, boot size, age and ability.
