The best advice I ever got as a budding cyclist had to do with cadence. The local shop owner, after watching me during a club ride, suggested I try to up my cadence a bit.
He likened pushing on the pedals to lifting weights.
When it comes down to it, it’s easier to ride at 20 mph with a 90 rpm cadence than it is to ride 18 mph with a cadence of 60. Don’t take my word for it though, try it.
One final tidbit, many cyclists come over from running… Runners tend to mash a harder gear at a slower cadence. I was once one and I rode that way because it more closely mimicked the pressure applied during a run…
