CTDThanks! Weight is on par with trekkers now, we are finalizing the design for manufacturing and will be doing quite a bit of finite element analysis to maximize weight reduction of the cut out designs, should be able to bring it down a good deal more as we refine it! They are alot more compact than trekkers and are massively stiffer.
treebeardLooks like you guys have solved pretty much every problem of the trekker, nice job. I know trekkers are a little finicky with certain bindings (fks/pivots), will yours solve this issue as well?
Ahmets_BrotherIt's about 3.75lbs right now for a pair. Keep in mind these things are burly and have literally zero play in them between links and the extra attachment point to maintain torsional rigidity.
Glansbergin907Stupid question but has anyone in here had the at style dynafit mounts pressed in their boots?
pros an cons much thanks winter is almost here!!
iLLbiLLySo around 1800-2000g per ski (depending on which binding you go with). It's a bit heavier than the cast system (only adds about 200g per ski), but a good bit cheaper (300$ VS 500$), and you don't have to modify your boot.
treebeardare you asking about retrofitting toe pins into a normal alpine boot?
Ahmets_BrotherYeah, The Daymaker Alpine Adapter is 800g per ski + your binding which is typically 1000-1200g so you're spot on. 1800-2000g per ski.
The cast system is 180g + 250g dynafit toe + your binding heel (500-600g) AND your toe piece in your backpack. so that's 930-1030g per ski and 250g in your pack while touring.
overall, you're looking at the daymaker adapter having 750g more weight than the cast system. The Fall/Early winter 16/17 run will likely drop our weight of 800g to 650g for Stainless Steel version, and 450g for the titanium :)
However some pros of the daymaker
1) transferable between all your skis
2) Standing height + 2 other incline heights VS 1 hiking height. more adaptability to the terrain.
3) Transferred carrying load to more under your tibia reducing the moment arm (torque of your ski depending on the placement of where the binding rotational point is) placed on your quad. This reduces fatigue
4) An increased normal force to the snow during uphill travel while your body is shifting into its next step. The 4 bar creates a larger platform to stand on and shifts your pivot point under the balls of your feet rather than your toe or in front of your toe. Moving this point back allows more of your weight to be above the center of your ski while taking an uphill step.
3 and 4 are direct results of a 4bar linkage versus a traditional single pivot design. I'll be updating with graphics and technical drawings in the near future!!

Glansbergin907yea treebeard wondering how that is figure i might as well switch to a boot that comes stock with them but still curious
Do the Daymakers stay in the binding better then my OG trekkers ive had a few traverses where i dropped a ski an looked like bambi on ice about 300ft from a summit haha but stoked on these Daymakers might give them a try... ...( trekkers for sale cheap cheap) haha
iLLbiLLyReally interesting stuff. I've been using the Solomon Guardian the past 4 years with mixed satisfaction. They do well downhill (except for changing the skis flex pattern) but I've broken 3 pairs going up. Haven't dropped into a tech setup yet because most the tours I go on are

Ahmets_BrotherYeah they will, especially if you have an fks binding they are bomber. very torsionally rigid with the 4bar linkage because of that 5" gap between pivot points on the ground link, and 2" gap in pivots on the boot link.
Ahmets_BrotherRather than producing the same thing that breaks, we will be continously innovating our product every season.
Come out west to slc and try a pair! or hell maybe we will do a demo pair that if the customer pays shipping they receive it and are charged on their CC if its never returned or small charges for late fees.... what do you think of that?

iLLbiLLyWeird! My post got cut short for some reason, but you managed still answered my question (I attempted to ask if guys would be open to sending a demo pair up to Jackson if I paid for shipping).
My only concern with the design is that the pivot angle looks to be a bit limited. I'm wondering if this would force you to pick up your skis and prevent a smooth sliding motion.
Ahmets_BrotherI'll have to post more videos on the website for you to see. I don't think the pivot angle limits your range of motion for a smooth glide, the pivot allows you to go just past what your normal knee/boot flexion would allow, but as for your ski dropping on kick turns at such -- There is a certain limit to the motion there, but nothing I've experienced to be limiting in my kickturn.
for instance, in the trekkar your boot would smash your toepiece of the binding at like 40 degrees of flexion. we never hit your toepiece, but with the 4bar i think our flex maxes at about 60 degrees.
Connor29have you guys heard of FT making a truing boot? When the rep came through town its something that he touched on lightly. He may or may not have said that they have a prototype haha
