From 1994-1998, I logged about 50000 km on my T700 while touring, commuting and training. My riding since 1998 has been sporadic but next summer I would like to do a 1500km tour from Red Deer, Alberta to Mission, BC - about 1200 km. I want to upgrade and fine tune the T700 which pretty much has most of its original components. (I have replaced the gearing a couple of times and the rear wheel once. It's currently a 21 speed with bar-endshifters (which I really like). Any suggestions?
