I saw Coach Dave Jordaan for a bike fitting as I had been developing chaffing on long rides. It turns out that as we get older some flexibility we always had is reduced (age 75). I rode my bike on his trainer and he observed my position. He was able to determine that the saddles I rode for 40 years were causing the problem. Dave had multiple saddles and he gave me one referred to as a "cradle" to try. It resolved a problem I had for 2 years. I am again able to do 100 mile rides with thousands of feet of climbing and am pain/chaffing free. If you have fitting issues he has the years of experience with high level cyclists and beginners to make your bike work for you.
