Record-12 brake clearance update

hi charlie, i dont think that would buy me much at all, there is very little clearance as shown.

to be fair, as donevwil pointed out, i think if this frame was designed with brake bridge placement to optimize for these calipers, it does look like there would be gobs more clearance, but as i sit, i'm definitely better off with the old units.

that's all OK too, the old ones look better and this is the biggest tire i'm likely to run on this bike too.

thanks paulo, i'll do some experimenting in the morning. i doubt it will make much difference on this particular frame, but we'll see!

Roger that.

you might gain some additional clearance by adding another serrated washer or two ?

My Record 12 brakes have less clearance, using Pro4 25s, than Chorus 11s. However, I do find the Record brakes seem to have more braking power. Agree they don't look as good.

Again, that’s disappointing to hear.
I have Campy 11 speed on my bikes; I had actually given thought to replacing the brakes with 12 speed. Not going to do that now.

So this not so much a comment on the brakes. Wow you have quite the wheel stash in the back ground of the picture.
Have a great day.

Lots of extra clearance with Record 12 if you want it, by adjusting the screw on the side.....

my rear brake clearance was tight so I tried Record 12 and here is what I found.

All of the below photos are on my Seven 622 SLX, all with the same brake shoes and pads. All are held fully closed against the same Zipp 303 FC wheel with a Veloflex Vlaanderen 27 tubular tire at 80 PSI.

1st photo is Record 11, (I could not fit a 2mm allen in, so maybe there is 1.5mm space)
2nd photo is Record 12 with the adjustment screw fully in (this is touching the tire)
3nd photo is Record 12 with the adjustment screw fully out (I did fit a 4mm allen in)

This is the post I remember.

Good work

Thanks Karl!

OK, just to close the loop on this one:

just went outside and fiddled with that adjustment screw. definitely helped! In the end it didnt buy me any additional clearance on this frame, so i'm going to stick with the 11-sp units.

i do think that if a frame were optimized with regard to bridge placement, the 12-sp would provide more clearance, but that's just not the case with this particular frame.

Just curious: are 11speed brakes compatible with a 12speed group, or has campagnolo engineered in some sort of modulation hurdle?

[Pastashop]

Am I missing something, or could a slightly higher brake bridge placement have worked with virtually any caliper to give substantially more room for a fatter tire?.. I really don’t understand why so many frames appear to have the brake bridges purposely placed to minimize tire clearance. (I could see how pads higher in the slots could give a bit more mechanical advantage for braking, but it really is inconsequential with rear braking.)

11 speed brake calipers are fine with 12 speed levers. As are 10 speed/9 speed/8 speed/etc calipers.
