Hello all. Over the past several months I have collected various parts for different bikes. They are from different Shimano lines and year. I have a long challenge ride coming up and I'd like to replace the gears and chain before the ride with the parts I have, but I am having a heck of a time finding compatibilty charts for all the pieces.

I am trying to mate new FC-5650 chainrings with a CS-5700 cassette and a CN-6701 chain. I have found documentation telling me that this will as well as won't work. The documentation in the cassette says that any super narrow chain will work so that looks good. I found one shimano document saying that the CN-6701 is compatible with the chain wheels, however I found a second document that listed the CN-6700 as compatible with the chainwheels, but did not list the CN-6701 as compatible.

Confused. Any help would be appreciated. Thanks!

This is the compatibility chart you want https://www.shimano.com/publish/conte...ty%20Chart.pdf

Mixing the components you have listed will work, less possibly the chain; the 6701 chain is symmetrical, when the 5650 doesn't need this, and you really should be using a regular non symmetrical 10 speed chain like a CN-6600.

Thank you for the quick reply. That is the exact chart I saw that said the 6701 (via a dotted line,... whatever that means) would work with my crank. Unless someone else can refute that chart, I'm going to give it a shot. Thanks again.

Does this matter, at all? I don't run 10-speed but I mix all sorts of other stuff. I do have 8 speed chain on a 10 speed crank and that works fine.

As long as the speeds of the chain/cassette/shifter match isn't that good enough?

Generally speaking, yes, the cassette/shift lever chain is what's important here. The chains get narrower with 9, 10, 11 but the interior of the link doesn't change, so it will ride on the chainwheel without issues. But the back end, the cogset, that's where the narrower chain counts. And of course the shift levers need to have 8 clicks for 8 speeds, etc. Other than that, people have run 11 speed RD's on a 10 speed machine, no issue, and plenty of people have run 11 speed chainsets up front with an otherwise 10 speed drivetrain, no issue.

It matters when you are giving advise based on info given remotely, A lot of components will work together out of their design parameters, but if you want to try this, your on your own. In your case an 8 speed chain on a 10 speed crank may work, personally I wouldn't, and wouldn't suggest it to anyone else.

Shimano give their compatibility charts for a reason; to give optimum performance from their products, if you like to take the risk of getting sun-optimal performance, go for it.

I've already cut the chain, so I'm committed at this point. I have this same chain on a Microshift Arsis setup I was testing. It shifts great but its noisy. I thought maybe it was the hollow style chain wheels on the FSA Energy crank, but maybe its the chain. This time its going on my daily ridden training bike, a 105 setup, that is usually silent. I really hope it remains that way.

Thanks for the replies guys.

Seems to be okay so far. I did throw the chain off the big chainring once, but I tired to duplicate it again by any means I knew of and couldn't. Hope it was just a fluke.

If it happens again, tighten the high limit screw a slight amount, maybe 1/8 turn.
