Dynafit Tech — Range of Adjustment and Screw Patterns

Bookmark and Share            By Lou

We get tons of emails and blog comments asking about Dynafit bindings boot length adjustment range and screw patterns. Instead of acting like a lame college professor giving a cloned lecture dozens of times a year, I thought I’d stick the essentials in a blog post (and make sure they’re in our Dynafit Binding FAQ), so here goes Part Two in “A Week of Dynafit.”

Dynafit binding adjustment range.

Dynafit TLT Speed heel unit base.

Photo above shows for/aft boot length adjustment mech for Dynafit TLT Speed. Range is 6.4 millimeters. Mondo boot sizing is done in centimeters, so range of this binding is around 1/2 size Mondo. Thus, consider TLT for/aft adjustment to be more for tuning to a given boot than for swapping various size boots.

TLT Vertical Rental, heel base underside.

Now about those screw patterns.

All Dynafit binding toe units use the same screw pattern. Speed, Comfort and Vertical all use the same heel hole pattern. Vertical Race, Low Tech Race, Vertical Lite all use a tighter hole pattern and require machinist level mounting skills because they have no for/aft adjustment. TLT Vertical Rental has its own unique heel hole pattern because it is so much longer.

Any questions, class?

    Thanks for the info Lou! I am a long time reader, first time poster… I really enjoy the thought and effort you put into your blog….

    Since this is Dynafit week, I had a quick question… I just bought a pair of Mansalus, and I really want to use them with my G3 alpinist skins. I heard that you basically took the rubber tips of your skis… care to go into a little more detail on how you did that?

    Thanks.

    Just got my skis back from the shop. I had the heel re-mounted so that I can adjust between my old 28’s (~316mm?) and my new 27’s (~306mm). Unfortunately, the original mount of my TLTs couldn’t move forward enough for the new boots. Two comments:
    1. Switching between boot sizes also affects the correct DIN setting. Follow Lou’s wisdom and don’t make DIN an ego thing or suffer the consequences. The difference is minimal for small differences in boot size, but it accumulates.
    2. Moving the midsole forward on the ski (switching to a smaller boot) should theoretically affect the way that the set-up skis. I don’t expect this to be noticable, but then again, I’m not the best skier on earth either.

    Thanks for the comments Pat, yeah, if you go to a smaller boot you in theory need less DIN. What I’d do if I were you is just set your bindings to the lower setting and use that with your longer boots and see if it works. Probably will.

    If you’re not a super experienced skier you probably won’t notice the change in boot/foot position on ski, but it can make a difference.

    Lou, thanks for being the Guru, and sharing the dynafit knowledge. her’s my question, is it possible to buy the vertical rental heel base separately, and swap it out for the ft12 base, so that I have an ft12 rental? or can you special order a ft12 rental? I plan on mounting them on DPS lotus 120’s and having the 12din + rental plate will make it easy to share the stoke.

    Thanks, Tom

    Tom, though it may appear I’m on Dynafit’s sales support payroll (grin), I’ll have to refer you to Dynafit for that one.

    Lou and Tom,

    Any word back from Dynafit as to the availability of just the rental heel plate? I want to be able to adjust the Dynafit heels 3 1/2 sizes so the rental plate would be sweet. My comfort bindings only adjust 21/2 sizes. We are looking to set my girl friend up with some ‘Good-” skis and I want to be able to “borrow” them. I plan to position her 20 mm forward of boot center, which will put me 15 cm behind boot center. Sound like a plan?

    William

    William, just call ‘em.

    I just got a pair of TLT Vertical Race Ti bindings. Does anyone know where I can download a mounting template for the heal? I’ve used the templates on this site to mount Comforts, and I’ve thought of just altering that template, but given the presision need to mount the heal piece, I’d like to get hold of the actual or a scan of the template that ships with the binding.
    Thanks!

Got something to say?
