Please refer to the NTN Boot FAQ for common questions about NTN Boots.
Why is NTN better than 75mm?
For now, this is the question. It's a hot debate that's being waged between those who've tried it, and even those who haven't. The arguments usually touch on releasability, lateral rigidity, activity level, weight, and cost of converting.
See the NTN vs 75mm comparison chart for more detail.
Where is 75mm better than NTN in it's current state?
Generally, 75mm bindings tend to be lighter, and those that a free-pivot touring mode tend to have much more range of movement than NTN's touring mode.
Should I switch my current setup to NTN?
The current consensus among Ttips users is that switching from an existing downhill oritented Telemark setup may be somewhat expensive, especially if your current gear is good and you like your current setup. The expense may not be justified unless some of the NTN creature comforts are a must-have or if you simply enjoy trying out the bleeding edge technology. Otherwise, it's highly recommended that If you are looking for an entirely new setup, especially if you're coming from an Alpine skiing background, NTN is specifically targeted towards those who are new to telemark skiing and spend time at resorts.
Will there be a lightweight NTN binding in the future?
As of the 2009/2010, there hasn't been any news of a lightweight binding from Rottefella.
Can I ski low (knee to ski) style with NTN?
Yes. It helps to use stronger springs at lower preload settings for maximum range of movement. See Selecting Powertubes.
How long does it take to adjust to skiing with NTN?
For most users, it takes a few days of resort skiing to get used to any technique changes. Some people adjust immediately to new gear, others can take up to a week or two.
Can I ski Parallel on NTN?
Yes, with the amount of lateral torsion and hold-down from the springs, it is quite easy to use parallel turns on NTN gear. However, NTN skiers won't be able to pressure the boot cuff as with Alpine bindings since the boot is made to flex. Parallel turns are possible, but the parallel performance will not be as good as a true Alpine system.
If you want to even go further, some users combine an NTN binding with a Dynafit heelpiece for use with Scarpa boots with dynafit fittings. See FrankenTele for more details. Again, this will still be subject to some amount of boot flex.
How do I step in?
Stepping into NTN bindings is easy. It does not require users to stoop down to engage any levers. Skiers just need to use the handle end of a pole for the second ski.
Refer to the NTN Tips and Tricks section for more details.
How do I avoid "tippy toe"?
Tippy-toe while skiing NTN is caused by lack of boot cuff pressure. If the skier solely relies on lifting the heel to flex the bellows and produce a telemark pose, they will often get a tippy toe effect. To prevent this, drive the cuff of the boot downward, and let the boot naturally flex. You'll get the boot to flex properly while providing more weight and power to the inside ski.
Are the brakes on Rottefella's NTN bindings interchangeable?
Yes. With a little fidgeting, you can swap out the standard 95mm brakes (which work up to widths for 100mm skis by bending) for the 110mm versions.\
Can I purchase NTN plates separate from the binding?
Yes. 2nd ski kits (which include 2 sets of binding plates, heel, and screws) are avaiable from most NTN retailers.
Can I mount NTN by myself?
Yes. If you're careful, you can the baseplate as a template and mount your skis. See the section on Mounting NTN Bindings.
How does the NTN mount point compare to 75mm bindings?
NTN mounts using a four hole Rottella pattern which is slightly wider than the standard 4-hole pattern. However, the base plates can also support the standard four-hole patterns. In this way, they are also compatible with Voile or the old K2 inserts. As suggested by Rottefella, mounting NTN is better where the boot center mark is matched with the boot center mark on the ski. In this manner, they mount more like alpine skis, though some folks like it better just slightly back about 1cm or so.
Can I use a Dynafit heel to look my boots down?
Yes. See FrankenTele
What is FrankenTele?
FrankenTele uses an NTN binding with a Dynafit heel. More details here.
Can I snowboard in NTN boots?
Yes. See the FrankenTele section.
