I remember when I got into cycling 15 years ago and my LBS suggested that my cadence should be between 90-110. I couldn’t do it and I thought something was wrong with me. I gave up and just pedaled at what felt right for me, my cadence is at 70 Rpm on average. I have completed many centuries and have done hundreds of 30 mile rides and let a 40 year old Clydesdale give you his 2 cents, if it doesn’t hurt and it works for you, do it. Another example, is when I used chamois butter on one time and I got horrible saddle sores. I know many people swear by certain things in life, sometimes the majority, but if it’s not right for you, that’s okay. Trial and error is a part of life.
