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!

Tried and True
Not much to say, tried and true chainrings. Converted back to 2x for my gravel rig, too much tarmac between gravel sections where I live, so went with 50x34 which was the sweet spot on my previous gravel bike. Lives us to Dura Ace standards, can�t go wrong.
