Just a note on the importance of getting saddle height perfectly dialed in.
I haven't been riding much this summer (new city, new house, tough at work, etc) so in the last 3 weeks with the drier weather in the PNW I start riding my 2 older road bikes. Something wasn't quite right, I didn't attribute it to my riding position but to a lack of fitness. Developed soreness on the front of my right kneecap after a few miles of riding at a moderate pace - nothing serious, but definately worrisome. Did I strain it with all the moving?
To make a long story short, I hopped on one of my newer road bikes this afternoon and went for a 20 mi ride - no knee pain at all. Tonight I found out that my son had lowered the saddle for his own comfort on the older bikes - "...only a few mm, Dad, I swear - it shouldn't make any difference".
Well only a few millimeters of saddle height adjustment can make a big difference. Thought I'd share.
