Maybe we need to spend less time on this forum and more time in the workshop like they did in the 70's and 80's

Work done to these calipers saved 175grams off the original stock calipers. see it here: http://www.velo-pages.com/main.php?g2_i ... ewsIndex=1" onclick="window.open(this.href);return false;

BRAKE CALIPERS:
Campagnolo Record (modified) - 48 mm to 56 mm "standard reach" aluminum alloy calipers - Clear anodized finish (removed) - non-recessed acorn nut mount - post 1973 and pre 1985 third generation chamfered center bolts marked "PATENT" (which were replaced - see notes below) - post 1976 C.P.S.C. compliant "cupped" style quick release levers and Black plastic wheel guide covers - pre 1980 quick release cam plate lettered "BREV CAMPAGNOLO" - pre 1981 without rubber bump stop on the backside of the front caliper arm - pre 1983 block lettered "CAMPAGNOLO" and "BREV. INTER." markings on the outer caliper arms (removed) - custom milled openings along the inner and outer caliper arms - custom milled relief slot at the cable adjuster end of the inner caliper arm - custom drilled holes on the front and rear end facings of the lower slotted section of the arms where the brake shoes attach - pre 1983 dome shaped center bolt cap nuts and quick release cam lock nuts - pre 1983 chrome plated brake shoes - model 2000 (front) / 2001 (rear) : post 1970 and pre 1981 Rondella Dentata tooth washers - marked "PATENT CAMPAGNOLO" - model 2041 : O.M.A.S. brake bolt kit - titanium center bolts with aluminum alloy fixed blocks - models 152 (front) / 154 (rear) : E.T.A. brake hardware - Black anodized 7075/T6 Ergal aluminum alloy - M6 center bolt cap nuts / M6 center bolt fixed cap nuts and flat washers / M6 brake pad holder hex nuts and flat washers - grouped model ETA-500 : E.T.A. brake barrel adjusters - 7075/T6 aluminum alloy - model ETA-501 : Scott / Mathauser brake pads - iron oxide compound - model "C" ... [In stock trim, these race proven Campy Record brake calipers would be correct and original as far as what would have typically been found on a Graftek G-1 sold as a "factory complete" bike. However, the particular versions seen here have been significantly altered by Jeff Rumbold of Oak Harbor, Washington (...who is well on his way to earning the mantle of "drillium specialist" extraordinaire in the finest tradition of Art Stump and Frank Spivey) and then further customized with decorative paint infill appearing inside all of the various "holes" and "slots" and thereafter fitted with an assortment of vintage appropriate aftermarket upgrades including some relatively rare O.M.A.S. titanium center bolts, an E.T.A. competition brake kit comprised of various Ergal alloy nuts, washers, aluminum alloy brake adjusters, and finally, a complete set of Scott / Mathauser brake pad inserts, the likes of which debuted midway through the year 1977. When compared with standard issue Campagnolo model 2010 brake pads, the Scott / Mathauser inserts alone provide a significant increase in braking power by decreasing the mean stopping distances achieved with these same Record calipers by a full 19 percent on dry pavement and 16 percent under wet weather conditions. And as for those nifty titanium and aluminum bits, while they certainly enhance overall corrosion resistance, when considered in conjunction with all of that "drillium" work, it all adds up to an aggregate 175 grams of weight savings between the two calipers when compared to their original "stock out of the box" state.]

Respect to those that can do that to components - definitely an art form, but the fact of the matter is most people can't ....and don't want to. At least I couldn't...without a lot of training, trial and error, bloody fingers and the correct equipment. :lol:
And if I could, I wouldn't feel safe riding with swiss cheese components.

I'm not sure I'd say it's gone there, but there are certainly some folks keeping it alive at light-bikes.de.

It's mostly in German, but in the "Selfmade" section you can find tons of awesome pics and projects.

I like to go back to this one when all the bikes work and are clean and there's nothing on the tele.

That´s the lowest weight I have seen for dura ace derailleur. The only thing I have against it is that the guy could have used more time to polish it then it would have been even more perfect

I know what you saying. But I think a lot of it, has to do with the manufactures of today. They are pushing the limits pretty good now on stock parts and of course after market companies.

It easy to to build a light road or mountain bike. Look, you can buy a stock bike under the UCI limits now. Order a few already made parts and you are under 13lbs easy.

That's the reason why I eliminated by gallery on the site a while back. No need any more. Or as you said, the art form is dying/died off.

Love the brakes. And honestly, we used to ride stuff like that and no one spontaneously self destructed because some of the parts were less stiff/more brittle etcetera.

All it meant was that you needed to be more careful under braking.

Careful about what exactly.

Start braking a wee bit earlier in tight, steep hairpins. But then again, we were younger and certain of our immortality.

I remember mounting a set of Galli brakes (then a popular "specialty market" brake set from a smallish manufacturer in Torino) replacing my Campa set, because they were... lighter.

The braking, IIRC, was not as good. But fine for a young racer with delusions of grandeur, and they served me well in my esordiente and juniores racing. Never won a race, but not for lack of stopping power... :mrgreen:
