My understanding is the larger chain ring is for going downhill, middle was basic and the smallest was for wind/going uphill. Sometimes I just feel like you are spinning and going nowhere on the 2nd chainring at a set speed and if you go into the highest and keep the same cadence and speed you feel so much faster. But then are you working too hard on your knees and legs?

I find myself in the largest gear a lot of the time as the middle seems like I'm spinning and going nowhere. Just wondered if in reality I'm mashing w/o realizing it on the 3rd ring even if I'm keeping cadence.

Are you able to customize the front rings to accommodate for your needs?
