Thank you for the thoughtful replies. More time in the saddle is important, & as fall comes around it will be harder to find. Finding the cadence which is right for "you" is as some of you pointed out is very individualistic. The mid to high 80s feel pretty good to me. TimothyH, I was using an old pulsar HR but my sons who also bought me the bike for Fathers Day gave me an Garmin vivoactiveHR my birthday. While I like it and it's features I find the HR is somewhat in accurate when I am on the bike. (20-30beats to high). If anyone else has one what did u do to correct the issue. Once again thank you to all of you
