Newest Campagnolo Brakes

[Lovetoclimb]

All things being equal, has it been determined that the newest dual pivot skeleton brakes provide more tire clearance? I would like to fit in a slightly larger road tire and am currently limited by my old Athena brakes (dual front, single rear).

I ride with 28mm Vittoria Corsas / Bora 35s (17.4 internal width) and campy CHORUS dual pivot calipers...plenty of clearance.

Seems Chorus and below, both dual pivot, seem to have more clearance.

Just sold a new pair of Record brakes due to lack of clearance.


Replaced with a pair of Dura-Ace 7800 brakes which give me oodles of clearance. Oodles, look it up.

anyone have a direct comparison they can offer? I may have to pull the trigger on some new Potenza brakes as an experiment to see if these 32mm conti 4-seasons will clear.

Non skeleton black record 27 mm tubies, I still have some room, so now the thing is that I might run out of room at the fork side

THe other thing to take in consideration at the time to put wider tires is that not all the time they are too rounded and is pretty easy to run out of room because of a tiny bump in the tire.

Current SR/Record are the same as the first Record Titanium which came out in 2007.

dumb question - what are "skeleton brakes" - are they just what Campagnolo calls their brake design after a certain model year?

Yes. The potenza style will give you more clearance than the record and up style of the current line up. I have both and there is a real difference.

Exactly.

I do not recall the intro year, but essentially like previous Campa dual-pivot/mono-pivot brakes but with cut-outs on the brake arms, like this, hence the "Skeleton" designation:

One of the big factors is rim width. If you run wide rim with the dual pivot brake the brake needs to be set open wider and this in turn brings the one long arm down closer to the top of the tire. The limiting factor becomes the tire height and not so much width.

The single pivot do not have this issue.

Can you run an older, single-pivot skeleton rear brake up front? Or is the mounting post too short in that case?

Some measurements for reference:
Conti GP4 Seasons 32 on a HED Belgium Plus rim (25mm ext.):
tire height = 31.2mm
tire width = 34.0mm

On another bike with a first-gen Chorus 11 skeleton dual-pivot rear caliper with pads at mid-slot and 17mm internal/25mm external width rims:
rim to bottom of brake arch = 28.6mm
A Compass 28 barely fits with ~2mm at the top (tire height = 26.6mm)

On the front, the 28 works fine on an ENVE 2.0 fork

With the early Chorus 11's the OP's frame is going to have to be set up to run the pads near the bottom of the slot for the big Conti to have any chance. I should have single-pivot measurements later this week.

This is the case. It is a custom built frame and fork, built to maximize the space under the Campy calipers I had at the time. Now I feel the NEED to run 32mm tires, 28 just isn't doing it for me ...

And it is ok on the rear, but about 3-4mm too low in needed tire height on the front. The brake is limiting, not the fork crown.

So it is either a newer style skeleton caliper like Potenza, or an older non skeleton caliper like a set of Record brakes for sale on here ... and failing that perhaps Paul Racers.

It is too short but use a way long brake 'nut' and it'll work.
