Lineups were also more extensive. A look on BicycleBlueBook of eg. Tarmacs in 2014, shows 4 models available with CF frames that fell in a price range of $2100 to $2950. (the progression is from Tiagra/105, to 105, to Rival to Ultegra). Today, the 4th model up from the lowest, costs $4,000 more ($3k vs $7k).
