Lightest double step sticks to date 1.2lbs

How about combining carbon bolts and a climbing stick? Instead of a double step just run CF bolt thru a stick top and bottom.

I think you could add a carbon step to a stick but the standoff is trickier
A carbon tee joint glued to the post might work with steps

If you could get a metal end cap and attach the steps to that you could drill a hole in them and run, either a cable with eye bolts on each end on a all thread through it and bolt it down! It might even help with the flexing by compressing the fibers, not sure how that works just brainstorming and not sure how much weight that might add just a thought!

More weight... might as well go Aluminium... welded aluminium sticks are very light.

Good to know the only sticks i have ever used are the old school metal ones! There is a store by me that sells them for $9.95 a piece! Cheap enough to leave on some pre-sets!

Proof that holes in carbon fiber are feasible

Just wanted to add that the way the CF is plyed for prosthetics(and other flat surface applications ie: see aerospace) is a little different than how it is for tubing applications. They orient the ply directions to create the desired support and strength versus less fussing with the ply direction because the tubed structure will have inherent support properties by nature of it's geometry. So not really apples to oranges... BUT... raises an interesting idea: you could probably have incredibly strong and thin CF ply that would withstand shearing forces of steps and bolts if someone were to engineer the plys properly. Caveat to all of this: $$$$$

I worked on a running blade project at my dayjob for a project sponsored through paralympian Blake Leeper. Pretty interesting project. I can tell that the running blades are incredibly strong, but also designed to withstand other dynamic forces such as flexion and torque, not static rigidity.

I did. I had a 12”X12” sheet of carbon custom built for me. I plan to use this for the steps. Still working on a design for stands off
 
I apologize as im late to this but have you tried a filler like the balsa wood previously mentioned earlier around step,standoff and versa button areas?

I ordered several pieces of balsa wood and by the time i got it in my hands I knew that it wasn’t going to be the answer. It’s very light but not something that’s going to hold up over time.
 
I'm glad this thread came back up. I bought a piece of aluminum from Dano at Saddle palooza to work on the carbon fiber sticks I have. The wall is extremely prone to Breaking from any force exerted by the bolts holding the steps are standoffs. What I had planned to do is cut a small filler piece of aluminum and insert it inside the carbon fiber tube. I was also going to drill the carbon-fiber hole slightly larger than what the hole was necessary in the aluminum. The real trick comes in getting the holes lined up exactly right. I was just going to make sure the aluminum fit snugly inside the carbon fiber cut grooves around the outer diameter and as the grooves passed by the bolt holes I was going to squirt epoxy in them and as much as I could inside the stick. I was doing going to line up the holes bolted down tight and allowed my epoxy to dry before putting any weight on it. I was hoping the epoxy would locked up aluminum inserts into the carbon fiber and not allow them to slide. Then all the bolt force would be exerted on the aluminum not the carbon fiber and the only thing the carbon-fiber would be doing is stopping flex and holding vertical Force. I don't know if it'll work or not. But the idea came from the original balsa wood idea I just figured like Swamp Fox Said the balsa-wood won't hold up where is the aluminum May. Small inch and a half inserts would not add that much weight. As soon as I get a chance that was going to be what I was going to try. What do you guys think?
