Where can i buy some screws like that?
I made a carbon fiber seat and i want to mount hallen screws because are more confortable. I wrote you a mail asking information
Thank you.
Soon i will show you my seat. I has an improvement.
I see T-nuts on the top of the seat but what did you attach to them on the bottom of the seat (that look like flat washers)?
Also, how did you get the prongs on the T-nuts to embed into the seat material?
I used regular stove bolts/machine screws and T-nuts with the teeth flattened. I could not find any T-nuts in 6mm so went with 1/4". You should be able to find them at any decent hardware store.
Edit: I flattened the teeth with pliers, they do not engage the carbon fibre. Those are flat washers on the underside. I glued everything with a generous amount of two part epoxy to hold everything together and help distribute the load to the whole area of the t-nut/washer. Not light but it should be strong.
I went for a ride yesterday with the saddle and I love how much stiffer it is compared to my old one.
Thank you
I will looking for them.
I used 1/4" T nuts on my carbon seat as well. I’d like to use KH hardware on my next carbon seat.
So is anyone making a carbon seat that has a built in “ramp” so I KH adjustable seat post or similar can be used? I use a Thompson after I broke a KH, works pretty well, light and strong.
One I done over a year back.
Custom CF base
Hi all,
Got this base made about 12 months ago, a friend of mine is a boat builder who does a lot of work with CF.
We made it to similar dimensions as the newer style KH seatbase, and after the first prototype we ended up coming up with this refinement that i’ve been riding ever since.
I’ve had the saddle on my 26" GUNI, which i rode on the Mongolia tour, and before hand during training. I’ve now put the seat on my 24" muni, and it’s still going strong.
Kris rode my guni with the seat base in Mongolia and commented how stiff the saddle was, even without any reinforcement. I’ve always had a KH touring bar mounted to it, and any flex when you really heave on the handle it quite minimal.
It’s all CF, with the exception of a thin layer of polyurethane honeycomb foam sandwiched into the front end of the base, with another layer of CF boxing it in. Makes for a light, super stiff saddle.
Cheers,
Dmacuni:)
Dmacuni, can you get more of those seat bases made?
If there was a big enough demand to justify making a batch of 10 or more, then my friend would be keen to make some more. The construction process is a little tedious, but we still have the moulds from the first couple of bases we made. 
^^^ I have an axel base and it’s amazing. 
Where can you get and Axel Base?
Mmmmmh… from Axel maybe? 
-> akaestle is the one youre looking for
what? so i can get a cf base from akaestle?? 
It’s good idea square.
But for me in this kind of screw (not yours that i don’t know, I speak about what i see in my place) quality is a little bad. Here in spain only are carpenters screws on iron and it breaks easily.
how much is the Axel Base, they come predrilled?
100$ + shipping
Do they come predrilled? How can I get one?
Hey Tim,
they are drilled, 2009 or 2010 saddle?
I can send you together with the frame;)
cheers Jogi
Unfortunately, I have to wait on the frame. I’ve had a few things come up and I also welded a MountainUni brake tab on my Surly frame. Will these seat bases work well with a rail type adapter. I have a custom handle that’s weed to a rail type adapter.
