What's the range of tolerance on the heel? I am looking at buying a secondhand ski drilled for a 310 BSL, and my BSL is 303. I don't want to re-drill.
As a follow-up, what's the consensus on adding an adjustment plate after a mount? Hesitant to unscrew the heelpiece as I'm worried any part of the process of heelpiece removal/plate addition would botch the original hole and screw up the mount...
Dynafit Low Tech Race 105 Binding
How can you tell if the Low Tech Race 105 binding is for you? Well, if you own more than one full-body spandex/lycra suit, if you get upset when your fancy European imported cheese is 6g lighter than the package says, or if you obsessively time your commute each day, this binding might be for you. Weighing in right around 105g, this updated Low Tech Race 105 (the name makes sense now, right?) has a reinforced heel to provide more confidence for those hot and fast race descents without tipping the scales out of your favor. Available with either automatic or manual locking toe pieces, as well as with a fixed or adjustable plate mount (plate sold separately), this binding can be customized to fit all your skimo racing and training needs. Whether you're lining up at the starting line or still just training for race day, the Low Tech Race 105 is a near-perfect binding for lightweight performance on the course.
- Optimized drilling pattern aims to decrease the chance of bindings pulling out of skis by evenly dispersing force among all four holes via hole placement and binding construction.
- Auto-locking toe piece has a smaller, forged aluminum release lever that does what its supposed to do very well-- automatically locks out when you step into it.
- Manual locking toe piece has a larger, plastic lever that functions identically to most other Dynafit toe pieces, to be skied flat or locked out.
- Reinforced heel unit should inspire confidence while descending, now able to withstand rough, off-piste descents.

Hi Nick,
When we're mounting race bindings fixed in our shop, our tolerance is +/- .25mm. Some manufacturer tolerances may be slightly looser than that, up to .5mm in either direction. But 7mm will not be possible to accommodate with a fixed mount. You need a 4mm gap between the heel of your boot and the heel piece - substantially more or less will compromise the release and/or retention. You may not even be able to step into the ski with the difference in BSLs that you are describing.
The good news is, adjustment plates are easy and don't hurt the ski! It's not a big deal to re-mount a ski with a plate, as long as you plug the old holes and leave at least 1cm between new and old drill holes. The adjustment plate will have a much larger pattern than the heel, so it's usually no problem to bridge over the old holes.

(Thanks a lot Jeff for the previous answer!)
I was trying to find the riser height (I mean how many mm) of this heel piece but couldn't, not even on dynafit's website. Do you guys know? Looks like around 30-35 but would be good to know for sure.
And the heel piece is identical to the Low Tech Race 115, right?

Hi Daniel, we measure all the riser heights. The 115 heels are quite similar but have no warranty support in the US.

Do you guys know where the guide leash can go on the toe piece of the automatic version? Or the manual version?
2/21/2023
Daniel, The binding includes a ring to attach a leash to. Comes in the packet with screws and crampon adapter. It would be added when mounting. If you look at a picture of the Superlight 150 you can see a picture of it installed.

Would this binding be appropriate for a Blizzard LT 80, 171 for a 175lb 50yo doing some rec Skimo racing, fitness skiing and Colorado 14er skiing and similar in the level 4 out of 5 range. Meaning- used to ski hard, currently washed up has been ;)

Hi Greg,
The Low Tech Race 105 is an ultralight race specific binding. For training and racing, it is a great option.
A 14er attempt could impart more force on a binding as compared with a skimo race. Based on your dimensions, I might go with something more robust for that application. Depending on your estimate release value, something like the ATK Trofeo could be a good option. If you would like to discuss bindings in more depth, I would recommend filling out a Binding Finder.

I have these bindings and the race brakes and I was wondering if the heel lifter can be removed so that they look like the ones that come with the brake here https://skimo.co/dynafit-low-tech-race-plus? If they can be removed, how would I go about it? Thanks!
2/25/2022
Thanks for reaching out, Ted. The heel flap is not designed to be removed and removal is not officially recommended by Dynafit. If you do decide to remove the flap, you would need to cut the pin holding the heel flap in the binding. The Dynafit LTR 105 brake can be used with this heel piece.

Did you do it? Did it work? Did the heel piece break apart?
Thank you very much!!!
Thank you very much!!!

Are these significantly burlier than the LTR 2.0 bindings and how does no flat mode affect crampon bite (I have never been able to get my crampons to bite in when risers are engaged)?
1/8/2022
Hi Dave,
The LTR 2.0 and the LTR 105 are both very much race bindings. Depending on your definition of burly, I would not use that label for either, as that is not their intended purpose. However, as a race binding, the LTR 105 is stout. On even the burliest race descent, you will be in good hands (or pins?). At 106g, they are pretty close to as light as you can get.
As far as ski crampons are concerned, the one riser option on the LTR is not particularly high. You should still get some teeth engagement. Nothing like flat mode, but it will be sufficient depending on the rocker (or lack of rocker) on your boots.

Absolute gems! I like the simplicity of the setup as I find it a breeze to snap in and out of and go from climb mode to ski mode. If you enjoy geeking out on light gear then these are for you. I chose to mount my Movement Race Pro 85's with these and they drive nicely paired with my Aliens. Lastly, others seem to marvel on how simple the setup is.

Hi, is there no way to add breaks to this binding? And what crampons are compatible with this binding? Thank you.
12/30/2020
Hey David, the only options would be to use the Kreuzspitze Tech Brakes that you would slide into your crampon receptor for the downhill and remove for the uphill or to use the ATK Universal Ski Brakes that use a leash release to engage the brake. As far as crampons go, dynafit, ATK, Hagan, and Black Diamond crampons are all compatible with this binding.

It sounds like it's a different mounting pattern than the previous LTR? On both the heel and toe piece or just the toe?
Thanks!
Thanks!
11/21/2019
Patrick, the toe is new. We are not sure about the heel. Still waiting to get our hands on it too.
Answer this question:

How would these compare in terms of durability to the Black Diamond Helio 110?
11/4/2019
Sean, that is pretty difficult to say. For the new LTR we can say the heel is stronger then before, but the toe is all new and only time will tell. As for comparison, they are both equally light and meant for race and training. Daily use and on big skis would be beyond its design.

When will this binding be available for purchase?

Paul, soon we hope. We just saw it today and it looks so nice. The look, design and finish is Dynafit's best yet.
10/23/2019
Hi Paul, we're told it could be as late as December unfortunately. Hopefully it will come sooner.
