I'm sure this subject has been overdone, but....I'm mid-50's, became fanatical about rod biking last summer, want to upgrade from Cannondale (a fine bike but too harsh). Will never race, want to climb better, go distances longer than 25-30 (4-5x/wk.) and be less fatigued at the end. Am getting conflicting info/advice on carbon vs. titanium. Good LBS's promote what they sell...so, they don't help much. Am not expert/experienced enough to know what's what. Am 6', 215. Looking at Kestrel Talon, Litespeed Tuscany or custom (which raises a whole different set of questions) Seven or Sampson. Advice/opinions eagerly sought and appreciated.
