I-beam seat rail to standard twin rail post adapter wanted!

Any guys out there savvy enough to design and make one of these for me?

 

I've been running SDG i-beam seat/post combos since I started MTB riding a couple years back.  Love the setup, light, strong and never had a problem with a seat moving.  I bought a Fox DOSS dropper a while back and had to shelf my i-beam setup but in turn traded my seat for a Fizik Gobi with carbon rails - so pretty good trade.  Last night I see both rails are broken off where the carbon is bonded to the seatpan... 

 

So now, I am longing for my i-beam seat on my DOSS and a quick google reveals people have thought of this - but no one is actually selling them as far as I can make out. 

 

So, if anyone is sharp enough to make me one - obviously I'll pay you for it, maybe it's also a good idea for you for a small side business.  The last link is the one I really want!

Looks like the DOSS and the Thompson is identical in clamp setup, so should be a direct fit.

I've mailed SDG directly this morning, but in my experience, companies like that seldomly respond...

So basically you like the ibeam seat itself because with an adaptor and on a normal post/dropper there is no advantage to the ibeam part of an ibeam saddle?

Maybe try Wtb saddles - win!

Whilst clamping system won't be as robust and simple as a regular i-beam seatpost, there is still the advantage of no rails to bend when landing hard on the saddle.

 

I also prefer the i-beam system.

 

To the OP... maybe ditch the Fox DOSS if you can source one of these...

I've never seen an i-beam seat break or bend. And I myself have bent and broken 3 or 4 normal railed saddles, so I prefer to stick to I-beam if I can.

Thanks Patches, but that's just throwing loads more money at the issue than I have available.

Can't Mr. C Swart help you out? As far as I can remember he has the resources for the design part (which I am sure you are more than capable to do too actually) and he must have good contacts with cnc capabilities...

Sorry for the late reply, yup you're spot on, I could design it myself... haha

Mr Swart is designing ships whilst being a new father, so rather leave him to tend to that.

Cape Tech Plastics' tool making shop is making the part for me, 70m from my office - so just a lunchtime wander away.

haha, haven't discussed it yet with the guys, will have to see...  Gave them a heads-up before they started to the max I'm willing to pay for the part, and so they knew that going in.  More than that I have no clue yet.

I must have a proper look. The seatpost that I am wanting to use should be able to take an Ibeam clamp. Then it is just a matter of swopping them around.

 

 

Naa, not what I was thinking
