Over time I've developed a fairly specific riding style. My rides are generally in the 15-25 mile range. I have no interest in speed and usually ride in the 10-15 mph range. I don't shift much and am generally in either 3rd or 4th gear (out of 7) I pretty much never use 1st or 2nd and 5-7 only on long flat straight stretches that are few where I ride. I do change PAS quite often but mostly in either 2 or 3 with 4 & 5 for steeper hills. I was just pondering whether my style is more or less harder on chains than if I shifted a lot or doesn't make much difference at all.
