For the ride home this morning, this week's trend of pushing myself to the end of my reserves on each ride was made all the more difficult by the fact that my seat post slipped down 2 inches. I felt like I was riding a BMX bike rather than a 15-year old MTB...
Bizarre.
I guess I have to readjust and really crank down on the seat tube quick release. I may have to switch out for a traditional hex screw/bolt combo on the seat post tensioner to hold up my Clydesdale frame.
