Oh yeah, slight adjustments sometimes make wonders.

I still have that "sliding down seatpost" problem on my hybrid. Took it on a tour this weekend with my husband, and on the second day I just could not climb any hill. Granted I was carrying a lot of weight on the bike and I was tired from the day before, but things didn't seem right.

At one of the rest stops I checked the saddle. It had slid down almost a whole inch!!!! I was climbing like a champ again as soon as I fixed it... (until it slid down again. have to fix that this week).

Glad you found your sweet spot!
