I've got my old GT hybrid for longer/messy trips, and my Brompton folding bike for the relatively short commute to work. The Rivendell was to be "do-it-all" bike that replaced the hybrid mostly.

But geez... the old GT sure doesn't ride like the Rivendell! Rivendell doesn't' really produce a hybrid per se, but I have the Sam Hillborne model, which is probably more like a relaxed cyclocross.
