Minimum cost to upgrade to SRAM doubletap?

Doubletap is starting to interest me, and I'm wondering if anyone has worked out the minimum cost to upgrade to something with doubletap from an existing Ultegra 10 setup.

From what I can tell I need: (Along with the best price I can find)

* Force shifters: $330 - Ebay
* Force Fr. Derailleur: $45 - Performancebike
* Rival Re. Derailleur: $105 - Performancebike

Is there anything else I'd need to change out? I'm assume brakes, crankset, cassette, chain and all fine from Ultegra?

I think you can find new Force stuff on eBay for the same price as the rival stuff you listed.

And to answer your question, I'm pretty sure you should be good to go.

I think that the front derailleur is not needed as well. Just the shifters and the rear derailleur. You can use your existing front derailleur. Someone correct me if I'm wrong.

I googled SRAM reivews since a friend of mine was thinking of SRAM components for his Pinarello.....the reivews that I found were NOT impressive. The problems ranged from the finish coming off the components after a short time to basic workmanship issues. There were about 16 reviews many of which were not positive. Just something to ponder and GOOGLE.

Is that from actual experience?

Allegedly both front and rear SRAM shifters have a different pull ratio than Shimano, which would necessitate a new FD & RD but I am just going from SRAM's website so I don't know if that's just propaganda or what.

I did a bunch of research on this and concluded that the front FD pulls are probably different, but not enough to matter. That being said, I went with SRAM Rival shifters and a SRAM FD shifting an Ultegra crank in my recently-ordered build just to reduce risk, especially with the lack of trim on the large chainring with the front SRAM shifter. Basically, I decided SRAM Rival everything was fine except for the crank where I much preferred Ultegra. But I was having to buy a FD anyway - if I were you, I'd see how your Ultegra FD does and replace it if you have to later.

As I'm sure you know, the RD and shfter definitely have to match.

Well, it is probably true that you can get away with different pulls on FD, especially just a double. If you were really hard-up you could probably do the SRAM-shifter-with-Ultegra-FD with no worries. But FDs are probably the cheapest component of the mix in question...I would probably just go ahead and get the Rival FD, too.

You may as well go Red brifters; small price diff from Force. I'd go Rival on everything else except FD.

I am running a Rival FD with a Tiagra FD and Sugino double cranks. Everything up front gets along just fine. Not sure if they are millimeters different or identical, but it definitely works. I have been told you definitely need a SRAM RD to go with SRAM levers however. So the cheapest route would be Rival shifters and Rival RD.

I have a DA FD on one of my bikes with SRAM shifters. Works fine.

RED brifters would be interesting (but yes, definietly not the "minimum cost"). There's significant improvements in the red shifters though, especially with adjustability for reach.
