Perfect match for lower gearing

I just replaced all the components on my 15 year old Seven Axiom frame. Since my frame has S & S couplers, I wanted wireless electronic shifting so I went with SRAM e-tap wireless shifters and derailleurs. All the other components are Shimano Dura Ace 11 speed including the crankset which came with 53/39 chainrings. The lower gearing was a little too high for my liking so I changed out the 39 tooth chainring for the 36 tooth chaniring I ordered from Bike Tires Direct. The change out was very simple and took no more than five minutes. Now my lower gearing is perfect!
