I have two road bike frames. One is a 58cm 1972 Masi Gran Criterium, a stage racer with fairly slack angles and long stays, sort of sport touring. The other is a 60cm 1985 Trek 760, a criterium bike with a 74deg headtube, 73deg seat tube, high bb, tight clearances, basically the antithesis of a touring bike. The frame to build up for my tour should be obvious right?
Trouble is I've never gotten comfortable on the Masi and I absolutely love the Trek. I use the Trek as my daily commuter and have taken it on 100+mile rides with no problems. My hands, butt, and back are hurting after riding the Masi 40miles. I've tried setting up the Masi with the same (or even more relaxed) position as the Trek so it should feel similar right? I've been trying for weeks to get a comfortable position but it's not happening. I'm leaving for my tour next week and am really tempted to swap my components over to the Trek.
So is it crazy to do extended touring on a criterium bike even if it's really comfortable? Should I keep trying with the Masi?
Pertinent info about my setup: I'm using a seatpost mounted single wheel trailer so the bike will have no racks or panniers. The Masi has 32mm tires with room for fenders. The Trek has 28mm tires with BARELY room for fenders. I'd have to ditch the Trek's fenders to fit my new 32mm touring tires.
The Trek is currently set up with bullhorn handlebars, which I love. The Masi has ergo-bend drop bars with brifters, for which I'm uncomfortable on the hoods. (Yes I've tried many handlebar/brifter position combinations.) I'm fine with older road levers on drop bars. I'm tempted to ditch the 9-sp brifters and go with friction bar-end or downtube shifters so I can use the bullhorns, though I appreciate index shifting. I have 4 favorite positions on the bullhorns, 6 for drops. Are the 2 extra hand positions on the drop bar worth the lessened comfort of my favorite position on the drops versus the bullhorns?
I know it's really bad to have so much flux in bike setup so close to the tour, but the bike setup I prefer (singlespeed race bike with bullhorns) is supposed to be a terrible idea for touring so I'm franticly trying to find an alternative setup that will work for me and for touring.
