I give up...

knownothingbozo

I have finally given up with my Planet X CNC brake calipers as no matter what I do I cannot get them centred. Ebay for them it is.
I am now left needing to get new brake calipers that will work with my Shimano STI levers - older style external cables.
Is there any reason why Shimano 105 5700 calipers won't work with these levers? Ribble say that they must be used with 5700 levers, but I can't see any reason why they wouldn't also work with the older ones. I have checked the compatibiloty chart provided with Shimano which seems to suggest the same thing.

Has anyone had any experience of trying this?

They'll work but they're just a pain in the ass to set up and they need centering far to often for my liking, you put a set of dual pivot on and the only time you have to touch them is to replace pads, Ebay them and go back to dual pivot.

The 5700 brakes will work but the cable pull actuation ratio is slightly different so set up is a little more critical i.e. new ones designed for more cable pull.

Since the cable pull is different you might find they're not great. I'd go for some 5600 brakes. Plenty on Google -

I haven't used Slane but Edinburgh Bike Co have always been good (I used to live there and had them as a local shop).
