Thanks all for the suggestions. First thing I intend to do is install a bike computer and see if I continuously maintain 90rpm. If not will start making investments one after the other on tires and SPD to help me achieve it.
Currently I have Bontrager H5 hardcase ultimate 32mm. Little bit on heavier side. Love its puncture protection and comfort. 25% of my ride is on packed gravels and crushed limestone. So 32 is minimum I need. H5 hardcase does appear to have some rolling resistance for its size though. Appreciate recommodations that would also help me with both road and forest preserve trails
