I dont see the problem with this FD. What are your questions which the Speci Support couldn`t answer?
it is installed correctlyerichwic said:Anyone have any definitive info on how to install the S3 XX direct mount front derailleur on the 2011 S-Works Epic 29er frame? I have it mounted but want to make sure I have it correct before I put any signficant shifting force on it. Specialized doesn't have ANY info on the issue and I just want to make sure I get it correct. I was able to speak with tech support and they were unable to answer all of my questions. Thanks for the help.
Well, the frame came with 2 little bags of bolts and washers, along with a FD mounting bracket. When I contacted Specialized support they asked for pics....I sent them what I had. They told me I had the wrong bracket and needed a new parts kit. The bracket the sent was the same and the part kit was totally different. So, I'm just making sure I have the right stuff. Just amazed that Specialized didn't provide explicit instructions on what washers and bolts are needed and where.S-Worker said:I dont see the problem with this FD.

Yeah, I've seen that. But it doesn't provide adequate information. You would think a $4500 frame would come with some decent manuals.Swami Scott said:

And maybe this is for convenience since every Epic owner gets the adapter, why not mount it instead of putting it in a baggie?), but SRAM makes its S1 derailleurs with exactly the mounting hole distance (42.7mm) that the Epic rear triangle has without an adapter http://cdn.specialized.com/OA_MEDIA/pdf/manuals/0262_IG_SRAM_XX_FD.pdf. I am wondering why this hasn't come up in the thread, and if someone could clarify please? I don't know if the x0, x9, ... lines are (or were late last year when 2011 bikes were being built up) available w/ S1 spacing, but the XX definitely is.
Thanks, hope this helps (someone other than my curiosity).
Sorry to awaken an old thread, but I'm struggling with S2/S3 right now, and trying to confirm.The SRAM FD's also come in S1, S2 & S3-specific fittings. The fitting (and the chainring-specific sizes) are stamped on the back of the FD.
S1 - Easy to recognise, as it is the only one with a 42.7mm gap between the centres of the 2x mounting holes!
S2 - Has a smaller 22.1mm gap between the centres of the 2x mounting holes. These 2x holes are also offset by aprox 5mm, with the front one being set further out (i.e. closer to the derailleur cage). The front mounting hole is almost flush with the inner cage of the derailleur when fully retracted (i.e. as it comes out of the box)
S3 - Also has 22.1mm gap between the centres of the 2x mounting holes. However, these 2x holes are flat, not offset. The inner cage of the derailleur sits a fair way out from the mounting bracket (aprox 16.75mm measured from the inside of the mount bracket to the outside of the INNER cage) when fully retracted (i.e. as it comes out of the box)

I suspect skiwi may have this reversed, in that S2 has the bolt holes flush, while S3 is the one with the front mount 5mm closer to the drive side.
I'm looking at a 2011 Stumpy carbon frame (26" HT) right now, and the holes are flush. In order to run a Shimano FD (which uses the S3/E2) standard, I'm waiting on an adapter (shim/spacer) from Specailized that effectively moves the front mount by 5mm.
Also, the Shimano docs all visually indicate the front mount as closer to driveside, so assming this also confims that S3/E2 a.k.a. "without backplate" is the one that isn't flush.

That said, wanted to doubly confim because even Specialized (Canada) was previously unaware of the mount on my specific frame, and was surprised when they ultimately looked it up in their database. Confusion to say the least.
