Seems like Dura Ace 7800 is one of those
products that has users that swear by.

What do you love about your 7800 bits?

What don't you like about your 7800 bits?

Grumpy McTrumpy

the only thing I dislike is that they stopped making it.

What's this? Some Campy curmudgeonosity wearing off on some of the Shimano folk?

I have some 7400 8spd in stellar condition for you Shimano retro grouches.

BTW...for anybody with compatiblity between 7800 & 7900, here is a good link: https://lib.store.yahoo.net/lib/trisp...patibility.pdf

I think Shimano perfected shifting with the 7800. The only complaints I heard about it was the cables not tucked under the wraps and the frrehub being exclusively 10-Speed. Let us all hope the second generation 7900 can get over the huddle of the "kinks" it has in the shifting.

And I like the 7800 cranks better than the 7900.

I think 7800 is one of the most beautifully built groupsets ever.
I especially love 7800 derailleurs.

For aesthetics I like 7900 shifters & brakes. Would look awesome on my BBQ CAAD.
I think 7900 shifters' adjustability and integral cable routing are big +'s.

Either crankset is out the window for me.
I just don't like them.

Surprisingly, 7800 prices were not far below 7900 prices.
I'm totally happy that I was able to piece together a 7800 group.

7800 is the cat's pyjamas and the dog's bollocks. I love that this stuff is nearly indestructible--still using the same cranks, derailleurs, brakes & levers from 2005. I've used up a few cassettes, probably more than a dozen chains, and a few re-cablings, but the stuff just doesn't wear out. I started buying replacements for when it does, but it's been languishing in my garage for just over two years now. If there is one nit worth picking, it's that the chains & cassettes don't last as long as the old 7400 stuff, but when you consider how much lighter it is and what a PITA it is to go back to riding an old 8-speed freewheel...

The 7800 crank is the sexiest aluminum thing since the late-80's C-Record.


7800's classic lines made it the obvious choice for my '86 Schwinn Peloton build (will probably be replacing the Sante calipers with 7800 this winter):

There's no way this bike would have had the classic look with that new, wonky, Lego-ish 7900 group Shimano came out with.

From an aesthetics perspective, 7900 is Shimano's Godfather III IMO. I've read a few folks in here who've said disparaging things about Shimano's rushing 7900's release. And I've heard a few @$$ram-fanbois tout their stuff, but even the Sram Red lacks 7800's buttery smoothness. Forsooth, both of the Sram-Red riders I've ridden with have a nasty KLONK when upshifting.

I had been thinking of putting Tiagra on my commuter, switching the road bike to a Sram mix, and selling the 7800 it has now. Lately, however, I kinda want to keep the 7800 and use it for the commuter (whether I keep this frame or build up a new one). The shifters really are buttery smooth.

2ndGen

A) Nice Scwhinn!

B) Do you replace cassettes/chains with 7800/7801?
Have you ever used Ultegra 6600 cassettes which
are said to last much longer than 7800's?

2ndGen

If I remember correctly, I think someone used Dura Ace
7800 Series chainrings on an Ultegra SL crankset.
Does anybody know of such a combination?

If I can accomplish that, I think it would give me the benefits of Dura Ace crankset
shifting with my 7801 chain/derailleur while keeping the crankset beautiful.
I'm going to assume that I'd drop some weight as well and, I'd retain the Ultegra SL's stiffness
(which is better than the Dura Ace's).

calamarichris

a) Molte grazzi signore!
b) Yep, been using 6600 cassettes on all but my event wheels, which really don't see enough miles to ever wear out.

2ndGen

Prego!

About how many miles do you get out of that set up?

(I specifically went with an Ultegra 6600 cassette for my Dura Ace build because of it's longer life than 7800 cassette.)

FWIW, I have 7800 brifters, RD and FD; 7950 crankset; 7901 chain; 6700 cassette.

It all works very well together.

Could do with ditching the crappy Cane Creek brakes though. 7800 would be nice.

botto 

pretty much.

I don't like having to trash a perfectly good shifter because of a ten cent spring.

mzeffex 

I like my 7800 crankset and cassette.

2ndGen

Why not just buy the 10 cent spring and keep the shifter?

I love this:

I opted for 7800 over 7900. The only downside I see is the weight difference and hidden cables look better.

rat fink

I was using 7800 rings on a Ultegra 6500 crank (now they are on a Dura Ace 7700 crank). It's a wonderful combination that looks and functions really well.

2ndGen

Thanks RF.

Would you happen to have a pic by any chance?

rat fink

I just did the 7700 crank last night, but let me look for the 6500 pic...

Here it is:



Don't mind the RD housing, I changed that right away.

cycle17

IMO, the 7800 Groupset is the perfect Shimano setup. Other than hidden shifter cables...it looks and performs great. I do use an Ultegra or 105 rear cassette for long life, but give me a full 7800 group over 7900 any day. One of the nicest looking cranksets ever made!

2ndGen

Thanks!

2ndGen

I only need to more things to complete my bike (groupset-wise):
Dura Ace 7800 Brakes and Dura Ace 7810 Pedals.
