I was feeling really tired and almost talked myself out of riding but I knew I needed to test the corrected bike fit. So here's what happened on the last bike fit adjustment... Everything was correct except the saddle height was 3/16" too high but that wasn't the issue, during the ride the rear of the saddle had dropped over an 1 1/4" down. This caused all the major muscles and back issues I had yesterday. the saddle drop could have happened within the first mile as there are a number of pot holes and bumps. So today I started out slow and 2 miles in was forced to speed up at a traffic light, so this was my first chance at putting down some power. About a mile further down o had to speed up out in the traffic lane to avoid drain grates and manhole covers on the shoulder. I notice I was able to get up to some speed and that felt good! So I picked up the pace from 16 mph to 20+ just to see how it felt on with the bike fit. Then I tested it out on a short series of rolling hills as tired as I felt, the rush of this fluid power and speed had taken me over. I was intending to go back into easy/recovery mode but that never happened. I just kept going, I did one smart thing, cut the ride short by 3 miles. I remember why I was so excited about this bike, it responds to your every move!
