Replacement for 6600 rear mech
Comments
-
6700 will work fine - have replaced a 6600 with a 6700.
alternatively a 105 5600 would do fine too0 -
I took the 6700 off my summer bike as a replacement (thinking i would replace it at leisure) but it won't index. I was told today by LBS that the pull ratio for 6700 was 1:1 but 6700 was 1:1.2
Can't get official information from Shimano as 6600 has now been discontinued and tech docs page links have been discontinued.
I wondered about 5600, but that appears to be the same design as 6700 not 66000 -
shimano tech docs say lots of their gear is incompatible - the 6700 mech works with 6600 shifters, i've done it!
5600 is the same series as 6600, 7600 so would also work fine
5700 is the same as 6700, 7700
shimano brings out a new dura ace, next year ultegra is the same tech, year after 105 ...
(9000, same as 6800, 5800)0 -
Any 10sp Shimano - DA, Ultegra, 105, Tiagra - 7800, 7900. 6600, 6700, 5600, 5700, 4600
Your LBS is wrong (which should ring alarm bells...) : all have the same pull ratio - it is different for 11sp (and 9sp, 8sp, etc)0 -

Get those series right!
5600, 6600, 7800.
5700, 6700, 7900.
7600 is a Dura Ace track groupset.
7700 is concurrent with 5500, 6500.0 -

Should that last 6700 be 6800?
6700 is 10 speed and 6800 is 11 speed.
That means where a 6600 came off the bike a 6700 can be used or a 6500 just not the 6800.
Isn't 6500 those ancient "Tricolor" ones?
Shimano 600. 0 -

Sorry for the typo. I meant I was told that 6700 was 1:1 but 6600 was 1:1.2
Thanks dgunthor and andy_wrx for your input.
Full story
October 2010, I replaced the Sora Groupset on the bike with Ultegra 6600; 6700 had just come out and the price was very low.
Last weekend the gears were skipping a little on 4,5,6. When I checked closely the cable adjuster on the mech had sheared. I assumed this was allowing a little movement and preventing proper indexing.
I couldn't find a direct replacement, but I did a lot of googling and decided the 6700 mech would work. I had 6700 on the summer bike, so thought to save time I would borrow this one and order a new one to replace it. I kept the same outers, but the inner was a bit chewed, so I replaced it.
I had difficulties indexing; if it moved smoothly from 8 to 7 and then back, I would need to add tension to get a clean change from 7 to 6. But then it would not move easily back to 8. This suggested to me a problem with cable pull.
Yesterday, I had to go to a meeting in a hotel just round the corner from a fairly new, but well respected LBS, so i called in for advice. Which appears was incorrect (but it seems there was a change in brake cable pull).
I had not had a recent off, so I don't think the hanger is bent; it looks OK. So I think the next step is to try new outers, as the ones on the bike are getting very old. I had intended to do this before summer anyway.0 -
There's at least four 6600 rear mechs on eBay right now.0

So the fully story is:
The indexing went out on the bike, so you went to adjust it with the adjuster on the derailleur and found that it was broken. So you replaced the rear derailleur with one from another bike (you realise you can buy just this part on its own?). But the cables are a few years old.
If I were in your shoes I would replace the cables now and try again. I get between 12 and 24 months out of the rear derailleur cables. If yours have been on there since 2010 I'd say you've done well!- - - - - - - - - -

Those are both 10 speed though.
So a 10-speed road cassette might not necessarily work with another 10-speed road component... now hang on a minute Charlie! :shock:
I would think any road rear mech would work except 11-speed (where the cable pull changes).
Now a guy says one ten speed mech is a 1:1 ratio and another 10-speed mech is 1:1.2, doesn't add up.0 -
The faulty mech was on my winter bike. I use this in the dark during the week. My nice bike doesn't have the same level of lighting, so can't use this is in the evenings. So I took off the mech to replace the one on the other bike for a quick fix. A new one was ordered, it arrived and was fitted today to the nice bike.
I went to my normal LBS, (not the one that gave me the bad advice) and bought a new set of cables, brake and gear. Fitted today to the winter bike, and all now works perfectly.0 -
Yeah but was that bad advice, thats what I was wondering, I don't know the cable pulls on them.
Why is Ultegra 6600 and 6700 both 10-speed? Are they really the same cable pull?0 -
There's 4 on ebay...0

6600 had external cables from the levers, 6700 has gear cables beneath the bar tape (6600 works better IMO).
not a lot of difference in the groupsets apart from that - think the 6700 chains were directional for a while, brakes a little better. generally wasn't worth the 'upgrade' to the new 10 speed if you had 10 speed.
yes, they are the same cable pull0
