I've been trying to research the reasoning or the marketing scheme for pantographed components but having trouble doing so. I typically come across on my late night eBay searches components such as a lever that has 'Somec" engraved in it or a crank that has 'Ernesto Colnago' all over it. My real question is what were these components for. Were they sold individually at bike shops as an upgrade or were these special orders from customers who wanted a little "bling" for their bike. And lastly, does it devalue a bike if installed. Let's say you have a complete 80s Campagnolo Record group set on your De Rosa and you remove those Record brake levers to install pantographed De Rosa brake levers. Is there any devalue or increase in value in doing so??
