Shimano 5700 vs r7000

Hello all,

I am currently running a 5700 set on my bike that works 75% of the time (10 speed). LBS told me I'd see performance gains re shifting performance if I swap out to the r7000 (11 speed). Does anyone have experience with the two that can confirm what my LBS is saying? Or am I being sold snake oil.

There have been improvements to the Shimano 105 line of products. Most professional reviews agreed that even Shimano 105 5800 which was the first 11 speed 105 group shifted as well as the Ultegra group of it's time. Weight was the only tangible difference between the two groups.

So there probably isn't any snake oil to the claims as much as it's probably just that your 5700 group that only worked 75% of the time is probably more of an indication that you continued to use it even after it was asking you to get it adjusted. So now it's beyond simple adjustments and no one sells new 5700 components any more. If they do, they probably want more than the price of new currently produced component groups.

I your bike only works 75% of the time, would be working out why, and fixing and replacing as necessary.

For 5700 vs R7000, not seeing how you can compare these too much today, 5700 is 10+ years old, and long OOP now; add to this, different cassette specs, if you have wheels which were on a 5700 bike from 10is years back, chances are they won't even be able to fit a 11 speed cassette.

For 'performance gains' at a consumer level, if well set up (which yours currently doesn't appear to be) it will be minimally noticeable if at all. For being sold 'snake oil' more a case it's going to be a lot easier to get compatible part for R7000 today vs 5700, as 10 speed Shimano road has compatibility issues with older and currently available parts if you don't know what your looking at.

Shimano 105 7000 is far superior to 5700. I have both group sets, the 5700 is ok, the 7000 is really good. IMO, the 4600, 5600, 6600 are better than the 5700, 6700 groups. The new 4700 gets really good reviews, but the lack of compatibility has to be a factor, for me, at least. If I had to choose, 7000 would be 1st, then any of the earlier 10 speed over the 5700/6700 group. It is a hard choice for me between the 6600 and 7000: 7000 gets the nod for tech and performance, 6600 performance is very good, but aesthetically, it is much better. Especially in the Ice Grey color. I am a bit partial to that group and own one.

IMO, your LBS is making a legitimate point and suggestion.

For the 5700/6700 (and also the 7900) these were the first under bar gear cable shifters from Shimano, and it was defiantly a learning groupset from them, For the 6700, did a lot of distance on that groupset, the shifters would fail at the 7-10000 km range, only have one set of 5700 left on a CX bike, whichare lightly used, will they fail? who knows.

I have 6700 and have posted that groupset can be finicky to dial in although I can get it but not much margin or error. I have 6800 on the other bike it shifts perfect 100% of the time and much easier and cleaner. In your case I could not deal with a bike shifting correct only 75% of the time period. You don't mention what model of bike this is one but if you like the bike to me this is a no brainer go R7000 even though you should be able to dial in the shifting. R7000 I would say will be much superior and just getting your shifting to close to 100% each time would be worth it. I don't have DI2 and as long as the mechanical 6800 shifts like it does I would have reason to ever go Di2.

My take is the r8000 would be super but probably not any real shifting difference. Go get the R7000 and then give me an update. That is because I will then do this and update my 6700 if you like it. It has been on my mind for sure.

Can you explain how it fails the other 25% of the time? As mentioned above, the 5700 shifters have a lot of cable friction and tends to be kind of vague feeling. Provided the shifters are not gunked up, you could try replacing the cables and carefully routing them to avoid any sharp bends. When I was running 5700 groupset on a Giant bike I had, I dripped some oil into the rear shift cable and solved a reluctant upshift issue.

You'll have to make the move sooner or later and it's not like your 10 speed is something wonderful like 6600 or 7800. If you can get 7000, go for it.
