Interesting bikes! Wish I had pictures of my bikes (maybe later).
I probably could ride anything on a century as long as it has a Brooks saddle. This year I've ridden all three of my bikes. The first is my 1999 Mongoose Ti RX100 (2 Centuries), the bottom bracket broke and I switched to my 1991 Trek 1100 (3 Centuries). I broke that bottom bracket and purchased a 2006 Giant TCR Composite 2 (CF). I broke that in with 3 Centuries, 1 double metric and a double Century in 29 days (total 1090 miles for those 29 days). I now have 6 Centuries, 1 double century, 1 double metric and a hilly metric. I'll lead another century tomorrow (90F tomorrow in the flats of the Barrens of NJ).
I'm currently torn between the Ti bike for it's handling and the CF for it's sheer comfort. The CF is too quick in the handling department. All my bikes have a Brooks down with a severe nose down attitude.
