Hi all, another old fart new to pushing the pedals. My present bike has a triple 48/38/28 in the front and 14-34 cog in the back. I’m finding using a gear combo of 2/4, with a cadence in the mid-eighties. My legs seem to be wind milling or I’ve run out the useful rpm range for that gear. Up to now my reaction has been to up shift to 2/5 or 3/4 to get a firmer feel from the pedals. Of course my cadence drops off and I’ll need to down shift back down for a bit to rest. Back and forth I go. Am I doing the right thing moving away for the wind milling sensation, or is that the sweet spot?
