Trek comparisons
What makes a Trek 7.7 FX worth $760 more than a 7.6 FX?
I know that there are about $250 to 280 worth of upgrades like Ultegra VS Tiagra front derailleurs, Shimano R770 10 speed VS Shimano SL R440 9 speed and Shimano crank VS FSA but as far as I can tell the differences are worth less than $300. What am I not seeing??
