I got a bike with 105, its pretty excellent considering I paid $15 for the fd and $23 for the rd. Its good stuff for the price

Tough to beat the bang for the buck of 105, and that's been the case for a long time.

[quickfeet]

I saw the newest version in a LBS recently and was shocked at how close it is to DA and Ultegra. Whatever my next crit bike is will likely have 105 and upgraded wheels.

I have 5800 and the performance is flawless and leaves nothing to be desired. It just plan works and it has never so much as missed a shift. My girlfriend's bike got a 5800 group when they first came out and hers is still perfect after lots of miles. Besides the weight I don't really see what more you could ask for.

It's long-term durability. DA shifty bits and bearings simply hold up better over time.

If you haven't already, try a 5800 group with coated da cables. Shifts better than 7900. At this point stiffness and brake power are all on par. Increasingly hard to justify a da group if you're not a gram counter.

16 ounces is a lot though. Is the difference mostly in the crank and cassette?

[bitpuddle]

Shimano has consistently trickled-down technology to the 105 group. The latest 105 is surprisingly good.

I think that front shifting is better on Dura Ace, but not drastically. Dura Ace levers feel a little nicer (more precise?), but that might be psychological. Dura Ace, in theory, should be more durable, but I’ve seen plenty of unmaintained 105 chugging along.

You mostly pay for weight and a nicer finish (though you can still get 105 in a polished silver color, which I thinks looks nicer than black).

16 oz sounds better than 1 pound.

After seeing and installing 11s shimano..105/ultegra/DA...not sure if 105 and ultegra way under priced or DA way overpriced..think it's the later..VERY little on DA(materials) to make it twice the $ of Ultegra and LOT$ more than 105..

These days, great choices..105/ultegra
Centaur/Potenza

[R3awak3n]

I was going to mention...

chorus to me is every bit as good as record/super record and costs hundreds less. Actually, I prefer chorus because it does not have the red in it. All the functionality for only a few grams less.

Potenza/Centaur is great too but powershift so I would not compare with the top dogs. That said, I guess a all Potenza and Chorus shifters would get you an affordable awesome grouppo

I own both 105 and Dura Ace. The functional difference is so marginal as to possibly be in the head. That said, it’s interesting that both reviewers picked out the D/A stuff blindfold. I possibly could top but the difference is truly small and even less if we invest in premium cables.

The difference in my case is aesthetic. No doubt the D/A looks better, especially after a few thousand miles and washings.

I can’t comment on durability as both of mine have been fine. Zero issues with D/A durability including their lightweight cassettes.

For the money 105 wins every time. If aesthetics matter, go Dura Ace. My 5-year old 9000 stuff still looks great and that is sort of satisfying I will admit.

[R3awak3n]

no question there, dura ace looks much better.

Even Ultegra, some of the finishes leave a bit to be desired. Dura ace polishes everything up but at a price.

Thinking about it it is more this, is Ultegra really worth it over 105?

[eddief]

453.5 grams.

16 oz of water = 473 grams.

I think I should drink less beer.

[sfo1]

Dumbest thing I’ve heard all morning. :beer:

Di2 Ultegra all the way (unless someone else is paying).

I don’t know if this matters these days, but DA has a 3 year warranty, while all other Shimano parts have only 2 years. Made a difference when Shimano STI shifters use to have problems, like back in the 9 speed days, and couldn’t be repaired. However, you rarely hear of STI shifters failing so it might not be a big deal anymore.

Of course, YMMV!

Good Luck!

PS - I agree, Ultegra di2 is the way to go!
