Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Sora --> Ultegra/Dura Ace

I was given a set of Ultegra FD and Dura Ace RD recently. I don't know if whether should I go through with replacing my current Sora ones. The Sora set seems to do its job fine.
Would it be enough of an improvement though? Also the current Sora set up is 3X8. These Ultegra/DA are for doubles I think.

I can sell it, but would prolly hurt the giver.

Why not slap them on your bike. You'll need to take apart your chain though. Shouldn't take anymore than 30 minutes to get them installed and tuned.

As far as I know, the RD and FD will work fine.

I don't think the FD will work. From what I remember, they aren't designed for that much travel.

I've got Sora on my road bike and on my TT-bike (with bar-end shifters), Dura-Ace. Sure, the DA shifting is somewhat smoother and tolerates shifting at higher force, but I've been really impressed with my Sora. After getting used to that thumb-shifter, it's flawless, even under reasonable pressure.

But for sure, Ultegra and DA should offer smoother, longer-lasting, and better tolerance shifting in the long run. I personally wouldn't shell out extra for it on my road bike since I'm so happy with Sora, but if I had the components in hand already as you do, I wouldn't hesitate to thrown on the upgrade. As good as Sora is, I don't think anyone can deny that Ultegra and DA are better and lighter. I don't feel that it's hundreds of dollars better by any means, but I wouldn't hesitate to upgrade it for free.

I doubt you can mix match Sora with Ultegra/DA parts especially with triple vs double though - probably should get help from experts with that if you're not upgrading the whole thing.

I may be mistaken, but I believe that you would have to at least change your left shifter as well for that combo to work. You can probably get a decent used pair of 6600 shifters for pretty cheap on the eBay.

I think the first issue is - would it work?

I've been told repeatedly that you can't mix 10 speed stuff with 9 speed stuff, and while Ultegra and Dura-Ace are 10 speed (the modern stuff at least), Sora and Tiagra are 9 speed.

And there's the "double vs triple chainring" thing in front - I believe Ultegra use different deraillers for double and triple, while 105 uses the same derailler.

I don't know what that guy is saying about getting "decent used pair of 6600 shifters for pretty cheap on the eBay" - when I was looking for a pair of Tiagra shifters, I had to pay around $100. And those are a level below 105, two levels below Ultegra. On midrange road bikes, shifters can easily be the most expensive single component on the whole bike.

This is not as simple as just changing the DR's. The DA RD is probably a 10 speed a, and the Ultegra is probably for double. To go from the triple/8 speed setup you have, you would need to change the shifters, chain, crankest, cassette, and BB for this stuff to work.

Probably not worth it if you are happy with what you got.

You can move the pulley wheels from the DA RD to your Sora RD-->they're much smoother than the ones on the Sora.

As it relates to derailleurs, you've been told wrong, repeatedly.

The rear derailleur will work fine, all of them are 8-10 speed compatible. The FD would require more research, the amount of movement is determined by the shifter not the derailleur, as long as the FD has enough range of motion it should work.

Thanks! I understand the DA rear der. should work no probs. However given that I have a 3X8, that means the chain capacity will exceed the DA which is a short cage.

The Ultegra FD.... I think is a double.

So bottom line seems like I would have to remove the granny ring to get it all to work which is not an issue as I've not used the granny ring ever. Hmm....

Save these parts for a future build. You can always use a backup bike and if the backup bike turns out better, then your current ride becomes the backup bike.

I already have a "backup bike". It's my hardtail mtb with slicks.
Oh you mean another backup road bike.... I don't think that's gonna fly with my wife.
As it is, my wife is already questioning why I have 2 bicycles.

You didn't say which rear DA derailer you have. The 8 speed DA is compatible, but you need to read Sheldon Brown on how to set it up to use with non-DA brifters. It's not a simple swap. If its a 9 speed DA there should be no issues. If it's 10 speed, I don't know if your chain will work properly (assuming you have 8 speed SORA).
If the front DR is for a double, it probably will not work with your triple.

Umm.... Used 6600 shifter sets sell on eBay for $150-ish all day long. Sometimes you can even get a pair for well under $150. Ditto for Craigslist, depending on your local market. Compared to the $350 that the current generation Ultegra shifters go for, I'd say that qualifies for "pretty cheap".

The granny ring shouldn't present too much of a problem with proper adjustment of the limit screws on the FD. Since you already aren't using it, you would just continue riding as if the 3rd ring wasn't there. It's the shifter that isn't gonna work with the FD, not the crank.

No way. That's at least 1,000% more expensive than the derailler(s) the guy got for free. Waaaaaaaay more expensive.

I tried doing a search "dura-ace 6600 shifters" on ebay - 0 results. Tried searching for "dura-ace" - got 2,183 results so I assume I'm not typing it wrong. "6600 shifters" returns both 105 and Ultegra results. If I do "Completed Listings Only", I get $199, $257, $117, $201, $250, etc.

Firstly, 6600 is Ultegra, not Dura-Ace.

Secondly (hopefully the link works):

https://completed.shop.ebay.com/i.htm...=p3286.c0.m282

Thirdly: I'm in no position to say whether it's a sound investment in order to get the OP's new Dura-Ace and Ultegra working, that's for him to decide. I'm only pointing out an option for him should he want to use those derailleurs on his bike. Perhaps a Tiagra or 105 set would be a better option, but since I have no experience with those and do not know their compatibility with his Sora/Ultegra/DA gear I can't personally make that recommendation.

That's because 105 is listed by "5xxx", Ultegra is "6xxx" and D/A is "7xxx"

May I know why wouldn't my front STI shifter won't work with the Ultegra FD? Sure it is designed with triple in mind. Won't that just mean, the 3rd click will just mean no reaction from the FD no?
