2 more double chainring combinations to consider ..

Popular 50-34, and less common 46-30. both involve buying a whole new crank-set and BB.

52 36 would be buying a crank-set as sold, 46-36 or 50-34 and buying the other sizes of chainrings..

decades ago I built up a 52-36 combo... the top gear on the rear, was a 13t, back then..
