I've got a modern carbon aero bike with Di2, disc brakes, 17 lbs, all the bells and whistles. I also have a 1964 Legnano, old school Campy, 12 speed friction shifters, 26 lbs. Guess which bike has my personal best avg. on my Malibu run on PCH? The Legnano. Surprised me too. I love tech, and I love old steel, but it's not all about the bike. Ride what you love, love what you ride. 😃
