Early weight weenie art - where has it gone.

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.]
