Now 51. Ridden off and on for years. Looking for new bike. Trek 7200, Giant Cypress, or Specialized Crossroads? Tested all 3. Liked the comfort of Specialized Crossroads the best. Want to ride 3-4 times per week. 5-15 miles each time. All 3 are hybrids. However, after reading too much, I question my selections. Will this bike be too difficult to ride from a comfort standpoint after 45 minutes?

Each model has upgrade with supposedly better components. Are they worth it in longt run. Trek 7200 over 7100, Specialized Elite over Sport, Cypress DX over Cypress.

All suggestions would be helpful. Looking for quality, comfort, less back strain, & fun. I live in SE Florida where there are no hills.
