I tried more bikes on Saturday.
They tried to upsell me to a Serotta titanium Fierte framed bike. The big difference, I noticed, was in the Shimano Ultegra components (vs. 105's or Tiagras).
I think I've narrowed it down.
I like the Trek 2.1 WSD (50 cm), and I also liked the Bianchi Imola (49 cm), but after feeling the smooth shifting of the Ultegra components, I think I want something that has those in it!
I went to Sammamish Valley Cycles, in Redmond. The salesguy I talked to there was a little pushy, initially, but he was great and gave good information. And he gave me great perspective: For every $1 you spend on a bike, you just ride a mile to compensate. Seems easy enough!
Anyway, I'm not in a big rush, and the SVC guy told me that once I had narrowed it to 2 or 3 bikes, to come in for a professional fitting ($200), and try all those bikes, and $100 of that fitting would be applied to the bike I chose.
I also want to try the cleats and pedals Melinda uses. They look more convenient than SPDs. I did some looking online and found out they were called Speedplays. The advantage I see is that they look smaller, lighter, AND you don't have to knock the pedal around to find the right side to clip into, which seems a lot safer than my SPDs that I currently use.
...more food for thought...
