Peter,
I love the Masi I have. It's the Premiare frame rather than the Evoluzione frame. Closest thing to it ride-wise is probably the Specialized Roubaix. When I bought it I forced myself to admit I was 50+ years old, and had no desire to do any road racing. Unless I enter the Merckx class at Texas ITT championships maybe, and the bike would be super for that. So, geometry is a little more relaxed than the Evo frame, and the carbon is a little more pliant. But, it's really responsive, the first time I got out of the saddle and jammed up a hill it just jumped. It's beefy around the BB, and I think that, combined with external BB keeps it really stiff. Handles well, stable on fast descents, and quick enough through hairpins and chicanes. Not winning any crits on it, but for long fast cruises it's the most comfortable bike I've ever ridden. Smooth, soaks by bumps that beat me to death on my old frame, but without a nasty dead feeling. Putting the Ksyrium SLS wheelset on made it even better. With Mavic or Michelin tires on it's perfect for what I wanted. The Kenda tires were an emergency backup when I found I'd cut both tires on a bad road, took them off a spare wheelset. Ergo bars took a little getting used to. One of the problems is they don't always mount the brakes as they should, and if you ride on the hoods a lot (I do) it's hard to get comfortable. Adjusted that and have been happy with them ever since.
Sorry to hear about the injury. Coming off an 11 month injury timeout myself, and that much time away from the bike is awful. I'm finally 100%, now just the small matter of this excess 20 lb (that's 9.1 kilos to you ha ha) hanging around my waist to deal with. Hope you're fully recovered and able to use real pedals soon. I've been riding Look pedals on-road since 1986 or 1987, have never cared for the Shimano SPD. I use Crank Brothers for off-road and urban bikes, I like the float, and I've never pulled out of one.
Looking forward to seeing your bike photos. I have others I'll post soon. My new project bike is a 1990 Cannondale Series 3.0 Criterium frame that I stumbled on. Really cool, even has a replaceable rear der hanger, unheard of back then. It's an SR600, so 105 equipped. BUT. I had pretty much retired my 1991 Ultegra 600 equipped Trek 2300 because I was worried about when the delamination was going to start. Think I'm going to move all of the components to the C'dale. Including the hand-built wheelset (Stan's 400 with DT Swiss Revo 2.0 spokes) that's on it. Should help the ride of that harsh frame. Oh, and the bike you see just below mine is Kim's Orbea Diva. She wanted to know why I didn't take photos of her bike. I told her that was her job ha ha! You might see it posted up soon.
