I know people who can (and do) get lost despite having GPS.
I went for the new bike fitting last night, after looking at it next to the old Madone WSD and deciding I probably needed to switch it for a smaller size (52). So the first thing I said to the fitter was that I was worried that the frame was just too big and the reach was too long to be fixed with a shorter stem.
I brought the Madone with me, and he started by putting the new saddle on the new bike based on measurements from the Madone. Then he compared some measurements between the two bikes (end of saddle to different points on the handlebar) and felt that the 54 would be okay. I rode it on the indoor trainer while he took some video and used some kind of software to measure a few angles. If you draw a line up the side of your back to the shoulder and then down to the hand, the angle should be between 85 and 90 degrees, and I was at 88. So we agreed that I would go out for a test ride and see how things felt. If necessary the next step would be to try an 80mm stem (down from the 90mm stem that came on the bike). And if I really don't feel right after additional adjustments, I can still turn in the bike and get the smaller frame.
We also adjusted the shift/brake levers. At the farthest out position I could barely reach them in the drops, but now they are close enough, I think. I might even be able to move them back out a bit. It looks like an easy adjustment to make.
BTW one big reason I decided the new bike would be a useful investment was that it is supposed to hold 4 water bottles -- three in the triangle and one more on the front of the down tube. There is a video on the Trek website showing the bike with 4 water bottles. Unfortunately it turns out that this is only true for frames that are 56 or larger. If you scroll down to the Q and A's, they admit that 54 and smaller can only fit the usual two bottles in the triangle. There are holes for a third cage on my bike but not enough room to fit the top bottle under the top tube. I might be able to squeeze it in but wouldn't be able to take out a bottle and drink while riding. It really amazes me that they would make a point of showing this feature on the video when it only applies for tall people. It's insulting.
Tonight I am going out to ride, but on the old bike. My wrist is much better after the crash on Saturday but still not 100%, and the route is too hilly for a first ride on flat pedals. And I just prefer to do the shakedown on a new bike in daylight and closer to the bike shop in case anything needs adjusting. So tonight, for old time's sake, I will ride the Madone.
