Campy brake release?

I was at my LBS after work to pick up a new tube. While I was at the counter a guy brought in a really pretty Colnago outfitted with Campy. In looking at the brakes it didn't look like they have a release mechanism so you can get the tire off. Am I wrong? are all Campy brakes like this?

There's a release on the brake lever with Campy, no release on the brake calipers.

You looked in the wrong place. Campy puts the brake release in the lever. It's a small button that sticks out of the lever near the top. It slides right and left, and the lever body is two notches to accept it. One sides notch is deeper, so the lever opens farther releasing the brake.

One benefit of on-lever releases as opposed to on-brake, is that brake function is never compromised. The lever opens more, and so does the brake, but it still works normally when the lever is squeezed.

As noted above, Campy puts it's brake qr in the levers, not on the calipers. This leads to some interesting mix-and-match possibilities.

If you use Shimano brake levers or brifters with Campy brakes, you have no qr at all.

If you use Campy brifters with Shimano calipers (I do on two bikes) you have two quick releases and the brake will open wide enough to clear nearly any tire.

my girlfriend has campagnolo chorus brakes and dia comp levers. with 700x23 tires its manageable. my guess is a 700x25 would work if you used the barrel adjuster (campagnolo has a ton of thread) but anything larger would probably require taking air out of the tires.

Right, with thin tires and relatively wide rims, a qr isn't needed at all and a long threaded adjustment barrel can serve as a substitute for slightly wider tires.

Yea Its an Era thing , back a ways Campag started the QR lever on the caliper ..

If you Puncture the tire will always be easy to remove ..

waiting to pump the tire up until after on the bike is also simplifying the installation
If its missing any QRs...
