Of course, but I only mention it because sitting side by side they are identical in appearance and measurement. Both have 16 inch stays, same bottom bracket height, same trail, same rake, same top tube length, zero offset seat post. Near as I can figure, the Scat has a 74 degree seat tube, a little lower bars, is just heavier overall, and all that combined weights the front wheel more. (As close as I can measure, of course) The Cervelo is harder on the sit bones. Maybe it was coincidence that the 2 bikes that fit me happen to have nearly identical geometry. In any case, "the wobbles' is something I am trying to take great care to avoid.
I didn't know that they made clamp-on racks. Up until now, I thought they needed attachment bosses. When I actually get far enough on this project to start packing, I'll take it under advisement. I imagine there is no end to the refinement when you actually start putting something into practice. No, I have never gone on tour.
You say people actually try to move weight up front? Now that is interesting...
I'll get some frame pics up when I have something picture worthy. I estimate pics in a day or 2 for the head tube work, and a week or so for the dropouts. Maybe a month or so on the other braze on type stuff.
