Getting the right ramp angle on your bindings can make the difference between skiing on-point or in the backseat with tired quads. B&D makes shims for almost every occasion. Choose a shim based on your binding and desired pin height delta, which can take some experimentation. Shorter boot sole lengths are more affected by delta because they end up with a higher ramp angle, thus look for thicker shims. Shorter skis also may benefit from thicker shims. For long skis and long feet, go thin to win. Some folks who shim their toes also increase the height of their heel risers to compensate. Do this with B&D Nubbins.
►ORDERING NOTE: All shims are sold in PAIRS, while the screws are priced INDIVIDUALLY.

18mm Pozi Screw - If you add some shims, you're going to need longer screws. These are alpine screws with a large head that works well with Plum bindings.
19mm Torx Screw - These are good for shimming lots of toes with 6.4mm shims. Small Torx head works especially well with Dynafit bindings. Find the screws here.
21.5mm Pozi Screw - Another alpine-style, large-head screw that works best with G3 ION and Plum models.
23.5mm Pozi Screw - Perfect for 4.7mm shims under Radical 1.0 & Vertical toes that already have baseplates. Medium size head.
28mm Pozi Screw - These are for raising the Radical ST or Vertical ST toes past 4.7mm, amongst other uses. Watch your depth, you may need to grind 'em down.
Hey Erica, thanks for reaching out, you'll want to get the "Classic" shims!

Question from
Derek
Due to a bad femur fracture many years ago I lost 7/8 in. in length on one leg and need to install a binding shim on one ski to balance me out. It would need to be at least 1/2 in. in height. Could someone point me in the right direction for which shim I could use? Thanks
Hi Derek, sorry to hear about the accident! The thickest shim we have for under the toe of tech bindings is only 1/4" inch thick, and we don't recommend stacking them. We have a few heel plates a touch thicker, but it sounds like you will need a custom job.
I purchased the classic 6.4mm shims with extensions to reduce the delta with Dynafit Vertical ST bindings and 28mm pozi screws as recommended. Unfortunately the 28mm Pozi screw head is too large to fit within the 5th screw (top screw) toe lever. 23.5mm screw fits but left me with not enough threads to feel it would be a secure mount.
The shims themselves match nicely and do reduce the delta to what I was looking at. Although with the 28mm screws, shims and extensions the added weight would be about 120 grams. Which is fairly heavy for an already fairly heavy binding.
Hi John, when you get into shimming you have to be ready to modify screws as necessary, including length and head diameter.

Question from

I am upgrading my old touring setup and was always unhappy with the uncomfortable combo of forward ramp and aggressive lean of speed radicals and my boots. My new bindings are the speedfit 10, which seem to have a lower (7.5 vs 16 mm) ramp, but intuitively I don't know how much of a difference this will make to feel and therefore don't know if shims will still make the setup more comfortable for me. Specifically, I hesitate changing my mind and having to reuse the same mounting holes if I add or remove a shim. Is this something I should be worried about? Any recommendations for me?
Hi Ben, the difference in the two bindings is palpable and there is a good chance it's "enough". Most skis should be able to handle the experimentation, especially if they have a metal topsheet.
Hello. Sorry. Auto correct made question unreadable. What shims would I use to reduce the delta angle on dynafit speed turn 2.0 by at least 3mm. Thank you.
Hey Matt, any of the classic shims will work for you, they will change the delta angle by 3.2mm, 4.7mm, or 6.4mm. If you want to change the delta angle by 6.4 a Radical ST 1.0 Toe plate under the Dynafit Plates & Bases will also work and in addition will look really svelte!

I have Dynafit ST rotation 10s and i bought a 6.4mm shim. I did not buy the screws with this. What screw size do i need? Do i have to buy these screws from you? My skis area currently in a shop ready to be mounted, but thye just realized they dont have long enough screws.
Hey Nick, yes the normal mounting screw for the Rotation 10 is a 15.9mm screw, and so if you add the 6.4 shim to it you need a screw that is 22.3mm. You'll want to buy the 23.5 screws and probably grind down the ends a bit so they don't risk puckering the ski bases.

Do you have a shim that would fit the Hagan Core 12 Pro?
The Torx 19mm screws would be the right size for a Marker Kingpin M-Werks 12 with 4.7mm shims. If you do not have the M-Werks version, I would recommend double-checking the length of the toe mounting screws.

Andrew Sargent
If I went with the 3.2/4.7mm shims for the Ion, and I was using them with QK inserts, I'm guessing I would probably want to go hunting for a 20mm M5 screw?
Hey Andrew, the screw that QK recommends for the Ion (without shims) is a 14mm flat head. Adding a 3.2mm shim comes out to 17.2mm, and I think an 18mm flat head screw could work alright. Adding a 4.7mm shim comes out to 18.7mm. There's a chance that the 18mm screw may be too short here, so carefully grinding down a 20mm flat head may be an option.
Went with the 4.7mm Shim and was using Binding Freedom inserts and a 20mm flat head screw worked perfectly. Only Bummer is I couldn't find it in Pozi, but my multi-tool has a No.2 Phillips that works perfectly for those toe screws.

Question from
Patrick
Is it accurate that the 19mm Torx screws are currently sold out? Looking to put the 6.4mm classic shims under my Speed Rads, and that would be the right screw, correct?
I have 4.7mm shims and 23.5mm screws that I am installing on the Radical ST. Due to the head being fatter than the stock Dynafit screws I will only get about 5mm of screw penetration into the ski instead of 8mm which is one less screw thread embedded in the ski. As a solution I am considered buying the 28mm screws and grinding them down. I'm just wondering how long the threaded portion of the 28mm screws is since i will be removing material. Also, just want to confirm they have the same thread pitch as it looks a little bigger in the photo. Thanks Skimo!
Hey Firnspeigel, the threaded portion of the 28mm screw is 12.5mm long. The thread count is just a bit less in the 28mm than the 23.5 and the width is 6mm instead of 5.4mm, but that screw should work just fine! You'll need to grind it down by about 3mm but it will still be very secure.

Max
I have a pair of Dynafit Radical ST bindings, and my boots my boots already have a lot of forward lean. I'm considering the 6.4 mm shims, and was wondering which screws to buy them with? First, do the bindings come with screws, and if not, which length would be optimal? I appreciate the help.
Hey Max, you will want the 28mm Pozi screw. They may need to grind them down a little so that you don't get any dimples on your ski base. It will mostly depend on what ski you have and you may not have to if you have a thicker ski. Lay everything down on the ski and see how far the screw will go into the ski and grind down accordingly. If you need any further assistance we are always more than happy to help, email us at help@skimo.co for any more questions.
Hi, I want to get a 4.7mm shim under my bindings on the ski as pictured. So far I’ve twice ordered what seem to be the wrong shims to fit these bindings. Do I need the the Radical 1.0 shims? Am I better off buying the Dynafit Radical ST Toe Plates to achieve the same rise? Thanks, Lewis
Hey Lewis, sorry to hear about the purchasing issue! The Speed Radical/Speed Turn toe pieces pair well with the B&D classic shims, which you can order in a 4.7mm. Don't hesitate to reach out to us by phone or email if the situation continues to confuse!

Steve N
I'm looking at toe shims for G3 Ion 12 bindings. Will the 4.7mm shims work with 21.5mm Posi screws? 6.4mm shims with 23.5?
Hey Steve, the Ion 12 toe stock mounting screws are 16.6mm long flat head screws. Adding a 6.4mm shim, you'll need the 23.5mm screws and possibly grind them down 0.5mm to match the stock screw protrusion.
My apologies, we don't carry any shims for the Alpinist binding.

Jeremy
Hi. I'm looking to put a 6.4mm shim under both Dynafit Radical ST 1 and ST 2bindings (2 sets of skis). Which screw lengths and head types do I need for each of these set-ups?
Thanks.
Hey Jeremy, for the Rad ST 1.0s you'll need full 28mm Pozi screws. For the 2.0s the 23.5mm screw should be more than long enough, since the stock mounting screw is 15.5mm in length (and you'll need at least a 21.9mm length with your 6.4mm shims). Happy de-ramping!
Jeremy, For your ST 2.0 use the 23.5 Pozi. The Radical ST (if also using the plate it comes with) you will need the 28mm, but check the length of your current screws, because you may need to grind off about 1mm.
