Okay, here's your chance to speak up!
We will soon be heading off to Acadia Natl Park and will take the tandem plus one of my solo bikes. The question is, which one? I'll probably ride at least one long day, 2 loops around the Park Loop Road (each loop 1200ft climbing, 16miles) plus a run up Cadillac Mt (1000ft, 3 miles up and one awesome ride down). I've done that run on the Raleigh, the Bianchi, and last year on the Masi. I'm tempted to take the Centurion this year. It's a bit heavier than the Bianchi or the Masi, but has a deeper low gear IIRC, and a 72.5mm crank which makes a 28T cog feel like a 29T.
I've decided that the priorities are different for this run than for most road riding. For example, the light feeling of the Masi doesn't mean as much as it would on, say, a ride of 75+ road miles. The pavement is perfection smooth so a soft ride isn't important. Climbing ability is essential. Stability at speed is essential. Oh, and did I mention brakes? The turns are sweeping, never tight.
But when you get down to the bottom of the brass tacks, the real issue is all about style.
