On one of my less frequently visited forums, there's a "Craigslist posters have gone nuts" -type of thread. If the 41 had a similar thread, I'd certainly have a candidate CL ad.
I've been using the Domane's stock rear wheel for the trainer, so I've been keeping an eye out for deal on a replacement. Just came across an ad for a take-off Bontrager wheelset from a Checkpoint ALR (aluminum frame, 105 groupset). The wheels are one or two steps below my stock wheels, which weigh in at ~2kg. The guy is asking $450.
