Shimano 105 FD 5800 compatibility with 5700 shifter

Alek

Is anyone using this combination?

My front derailleur is on its last legs (thank you cyclocross) and I like the longer arm and looks of the 5800 series one. Will there be enough movement from a 5700 shifter to run a double?

I don't think so. A longer arm means more of a cable pull.

Yes, but currently (5700/5700) I have to stop the movement outward with the screw. If I undo it the FD goes further than necessary - maybe it will be just-about enough to operate the 5800 mech?

There is one short product review on the internet that says it works ok (evanscycles Q&A on the product).

Sounds like a stretch to me

Did this work for you ?

At the end I have found an old and cheap Sora 8sp mech and it works better than the original 5600 No chain rub in any gear combination, as it is designed for slightly wider chain.
