"Bicycle Quarterly has done a lot of research on
what makes an optimized randonneur bike, but you can
use any bike for randonneuring. One of my friends
rode several seasons, including PBP, on
a carbon-fiber LeMond (above). Another friend rode
a 1980s Trek on many brevets, including a 24-hour
Flèche Vélocio.

I'd like a steel frame but thanks anyway.
