I'm not sure how to thank all the repliers for the tips. But thanks. What I did was 'not let my speed be that important. I was conscious of cadence, or rhythm, since I'm a musician, breathing and keeping the shifting more in the middle, that may not make sense even to me as i re read it. I have not lowered my seat yet, just did 20miles, little wind but several 20-45 degree hills, took me 1.30hrs. but as I sit here writing, my knees did not, are not hurting. Save'd a trip to the shop and a fit fix charge. Thanks again and if every I can help, i will.
