Anyone riding the new 105 11-speed grouppo?

I've had 105 10-speed on my cross bike for the last 5 years and it works just as good as my Dura Ace road stuff.

11-speed Shimano requires a new cassette body. When I got my Indy Fab Gravel Royale last year I made sure to get White Industries 11-speed hubs. Likewise, this year when I got my Giant and installed new stuff I got ENVE wheels with 11-speed DT-Swiss hubs.

Campagnolo hubs are 9/10/11 speed compatible and I've heard that 11-speed Shimano and Campagnolo are interchangeable, so if you have Campagnolo hubs you can use a Campagnolo cassette on your Shimano groupset.

Clear as mud, huh?

Given the praise for 11-speed 105, I'm sold. I just got a new (to me) bike with 10-speed 105 and I've been considering upgrading to 11, primarily so I can get the new mechanical/hydraulic disc shifters in the future. (From what I've read, they'll be 11-speed only.) If the quality is what it sounds like here, it'll be a great upgrade.

Ah bummer that is what I was afraid of. I guess blocking out one gear and running ten speed would work tho.

I took my 12t off and ran spacers behind the cassette till I could find/buy enough 11sp wheels for CX. Works, but its a spendy way go get that new front derailleur.

I just inherited a more-or-less new 5800 rear hub. Now I gotta decide what to put in in. Edited to add: There's a set Major Tom wheels that are hanging in the garage with crap hubs in em. Time to fix that small issue.

Is there a definitive answer yet on whether the 5800 group suffers from the same cable fraying/breaking problems as the 9000 and 6800. With the caveat that I might have missed something, my research suggests that there were problems with original 9000 shifter cable routing. Shimano attempted to fix that for 9000, and the 6800 group was not supposed to suffer from it. But, searches on the web turned up 6800 owners with early cable fraying / breaking problems. I find the 5800 group very appealing, but would be turned off by cable failures in <2000 miles.

Ribble is selling 5800 groups for about $365 which is the best price I've seen. Just a heads up.

Just FYI, Ribble is having a groupset sale today, just ordered a silver compact 5800 group for $358 delivered. Even if I wind up paying the $22 in duty and fees, still cheap.

Similar savings on 6800, Sora and Tiagra.

Perfectly adjusted SRAM Rival does not feel or shift as crisply as perfectly adjusted Red.

The differences between 105 and Dura Ace are in weight, price and finish (not insubstantial, mind you), but not in shifting performance or feel.

I suspect shimano is making some good $ on 9000...looking at some 9000 OE bikes, it's as if the frame or the group, is almost free.

But performance? ala SR/Record/Chorus..samo-

All of you failed to read what I wrote. I said the difference was in FEEL, not PERFORMANCE.

May need to correct your prescriptions...

With the Ribble sale coming to an end tomorrow, I just thought I would bump this to see whether anyone has any input on the above.

Um, perfectly adjusted Athena does indeed shift as crisply as Chorus/Record/Super Record, which all feel and shift the same.

[beeatnik]

Black Dog, don't know anyone who has gone from SR/R/Chorus down to Athena and thought, "um, feels the same, works as good." However, the reverse may be more common.

I only see a difference in weight and aesthetics when compared to Dura-Ace/Ultegra. I am a big fan or the Dura-ace hood design though. Feels right to me.

[ahumblecycler]

I can only contribute to the 6800 vs. 5800 debate as I have a few thousand miles on each.

5800: shifters, FD, RD and 6800 46/36t
6800: shifters, FD, RD and FSA SL-K 52/36t n10 rings

Both with Shimano housing/cables

Honestly, I have been unable to identify any real performance differences other than front up-shifting, which I attribute to the larger difference in teeth count. I liked the 5800 so much that sold off my Red22 and Force22 groups. I will take the hit in extra grams to keep extra dough in my pocket.

My only complaint is that Shimano limits the cassette range options in the 5800 family. I prefer 11-23/25 but instead will use 6800 going forth.

[Deucer01]

I just refreshed my 2013 Scott Foil 40 with 5800. Shifts and brakes much better than the original 5700 ever did. And the extra gear is nice. Also like the feel of the new brake hoods.
