Hey guys. I'm pretty new to cycling and I could use some clarification on this. Please forgive my simple newbie talk.

The way I understand what you've been saying is that if i'm in the 2nd gear upfront and the 4th outback, I will feel a bigger difference if I stay in 2nd up front and swith to 5th outback... rather than switching to 3rd upfront and staying 4th outback. But I've always felt like swithing the front gears makes a huge differnce, and switching the rear gears only made a small difference.

Could you please explain this some more.
