Got a Henge carbon rail saddle for my S-works Epic. Only problem is that specialised tell me they don't make a clamp to take carbon rails that fits their MTB stems - where the clamp fits is a larger diameter than the road bike - so the clamp they sell for 7*9 rails doesn't fit the MTB post! FFS Specialised are really p*****g me off.

Anyone got a suggestion as to what seatpost will fit the epic and take the 7*9 rails? Or do I hand back the saddle and get a refund. I mean WTF are specialised doing making MTB saddle that you can't fit to their bikes - DUMB

No It dont

soz but got one of those and it does NOT fit the seat post fitted to the SWEpic. Also specialised have told me it doesn't and that they do no make one that does fit that post. The diameter where they fit into the post is much larger on the MTB than the roady (a Roubaix). The 7*9 clamp fits the Roubaix but not the Epic.

PS that clamp is alos under the roady seatpost section not the mtb seat post section on specialised webpage, ands it s name suggests it is made for the Pave seat post, which is 27.2 in diameter, smaller than the 30.9 of the mtb SW carbon seatpost.

What does the first part of your response say? You may be right that it doesn't work but I was told by specialized customer service that it will. They went and actually got the seatposts and a tech, I don't think they were just jiggling metal around in the background.
Pave is just the name, it's also the name(or was the name) of the 30.9http://cdn.specialized.com/OA_MEDIA/pdf/manuals/06_309_Pave_Carbon_Seat_Post_instructions.pdf

Seems to be a bit of miscommunication between Specialised and its customers! Hopefully they've miscommunicated to me.

I'm looking at my anodized Pave seat clamp 7*9mm ( Specialized Bicycle Components : Anodized Pave Clamp 7+9mm) and my S-WORKS Carbon MTB Seat Post (Specialized Bicycle Components : S-WORKS Carbon MTB Seat Post). The the clamp does not fit the seatpost. MY LBS rang Specialised whilst I was there, specialised also went out the back and tried to fit the clamp to the above seatpost - the result was they couldnt make it fit. They then looked through their parts catalogue and said there was not one available anywhere in specialised parts and they didn't make one. The LBS has offered to refund the cost of the saddle.

If yours does fit I'll be ecstatic, just post here and let me know. However, I'm a bit sceptical as this is not the first problem I've had with Specialised - great bikes but the company - hmmm? Also the fact that the clamp is in the road seatpost section of the website and not the MTB seatpost section may be an indicator.

the first bit? Soz = sorry - i Got one of those clamps. Hopefully they have made some and you are getting one that fits the SWorks mtb seat post. certainly hope so.

Re the video - yes it does but on what post and have they made a clamp specially for it?

Well if you've got one in your possession that is more facts than I have.
That is the s-works mtb post in the video but specialized could have had those clamps custom made if yours don't fit.

Tonight I pulled a Pave clamp out and tried to use it on my S Works XC post and it was too small,
Yup - and they don't make any clamp to fit the S-works MTB seat post - In addition the rails are not 'standard' at 7*9mm. Others make theirs 7*9.8mm. So we have wonderful carbon rail Specialised seats with no way of fitting them to our wonderful S-works MTB's. :madmax:

Maybe their carbon rail seats are too weak to be used on MTB's so they make sure you can't fit them to their bikes - wouldn't mind betting thats the problem.

Specialised are often just bloody stupid IMO. Although I like their bikes I've had it with this company that seems to indulge in false advertising IMO.

You may also want to check that your S_Works MTB came with ceramic BB bearings as advertised. According to my info NO S-Works MTB is fitted with ceramic bearings, so it is NOT a change of specification as they claim. They fitted with steel ones that often seem to lock up. :madman:

I might as well add fuel to the fire. You can buy the same style adapters for bontrager seatposts for $12. I think Specialized is using titanium though. Bontrager: Seatpost Head Parts (Model #06096)

Anyway, I don't think they'll fit, but I only have a bontrager seatpost on my road bike and the diameter of that cone is significantly smaller than the ones on my s-works seatpost.

As for the S Works SJ HT that post will be fine with the carbon rail saddle. I assume that seat post is the same as the road post on my Tarmac.

Even if they fitted the Specialized seat post the rail sizes are different - Bontrager uses 7*10 rails, specialized 7*9 rails and others 7*9.8. FFS!! :madman:

Buy a Thomson masterpiece, throw a couple Ti nuts,bolts on it.

Then it sits around 180grams or less & is quiet, reliable & 60+ grams lighter than a specialized seatpost.


I have two of them with carbon rail seats, Im sure there are a few people who have lighter, but a Thomson masterpiece is somewhat cheap, light & you can get almost all your dough back, if tis not needed.

Thomson is alloy, the spec seats I have used are carbon railed 7mmx9mm.

as long as the post clamps to the top and bottom (such as Thomson), its fine to use with any carbon rails. Correct?

Problems are run into when its a post that clamps from the side.

and FWIW, its spelled SpecialiZed.
