Brake caliper compatibility

[PaulSecteur]

Hi,

Does anyone know (Not speculate please!) if it will be ok to use shimano 105 5700 calipers with 105 5600 shifters?

I have tried to contact shimano to ask, but I cant find a contact.

according to ribble the 5600 shifters don't have the pull ratio for the 5700 calipers

After looking round the net it would appear they are not compatible CRC says this

"Must be used in conjunction with ST-5700, ST-6700 or ST-7900 STIs for correct leverage ratio"


Can't you just use the 5600 calipers thats what I have and they are fine.

You could try here -> CLICK ME dont know if they will help but maybe worth a try.

In case you need any specs etc for the Shimano 105 the Tech Docs and exploded diagrams with part no's -> CLICK ME

I could use the 5600, its just that Ribble has the set for £40 but only in silver, they have the black 5700 for a few £ more.

I read similar when I got mine, decided not to risk it and bought the ones I knew would work.

Ah right ok I got that problem when I got mine I wanted black and I got mine of ebay, it was either absolutecyles or highonbikes I can't remember which. When I got mine the 5700 had only just come out and I remember everyone saying they didnt think they were compatible with the 5600 levers.

Just had a quick google and these guys are showing the 5600 set in black -> CLICK ME and also there is a set on ebay here -> CLICK ME

I recently bought and put Shimano 5700 calipers on my single speed bike.
My brakes work fine. Don't know what make my brake levers are, Techno or something.

And thats the sort of thing thats confusing me!

It seems they wont work with the 5600 shifters, BUT lots of people have them on with other levers, not even shimano. Im half thinking its a shimano ploy to get people to buy new shifters too.

What to do, what to do..?

 

[phil_hg_uk]

Have a look at the tech docs in the link I gave you there is the parts diagram in there and compare the two side by side see if you can spot any major differences.

Basil is probably using Tektro levers.

 

[Basil.B]

Sorry to confuse you even more!

 

[Basil.B]

Tecktro, cheers! Got them off a mate.

No problems, work a treat.

In the back of my mind I think you could be right but it's if you want to risk £50 on it or not.

Sure. Paul the official answer is no, unfortunately, due to different cable pull ratios.

 

[phil_hg_uk]

Thats a useful chart I wish I had found that when I was upgrading my chainset would have saved me ages

Just looking on another forum where someone was looking at using the 5700 levers with 5600 calipers and the shimano tech guys said this:

"The new Shimano 105 ST-5700 model STI levers are suitable for use with the older RD-5600 model rear derailleur. The 5600 series front derailleur and brake callipers are not compatible, as they use different cable pull ratios".

Which backs up the different ratios theory.

And youtube agrees...
